A sphenoid sinus mucocele is a location-specific subtype of a paranasal sinus mucocele From January 2001 to January 2007, we treated 75 patients affected by paranasal sinus mucocele. Out of this number, 8 patients (11%) presented an isolated localization in the sphenoid sinus. These patients were divided as follows: 5 involved the right sphenoid sinus and 3 involved the left sphenoid sinus Abstract Seven examples of mucocele of the sphenoid sinus have been described. The characteristic symptoms and signs have been described, and the diagnostic neuroradiologic features have been demonstrated. The condition is not a benign one, as is demonstrated by total blindness which occurred in one patient (Case 2) â€˘ Sphenoid sinus mucocele is a rare entity that can occur alone or as a result of ethmoid sinusitis and polyposis. A myriad of presentations is possible due to the presence of important contiguous neurologic and vascular structures. Past surgical approaches to the sphenoid sinus have problems..
The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material enclosed by cylindrical pseudostratified epithelium
COMMENTS A mucocele is a sterile accumulation of mucus in a paranasal sinus. Its occurrence is due either to cyst formation in a mucous gland or to blockage of the sinus ostium by injury, t u m o r or inflammatory changes. T h e y are most often found in the frontal and 991 992 AMERICAN JOURNAL OF OPHTHALMOLOGY DECEMBER, 1970 Fig. 2 (Stanton) Sphenoid sinusitis is an inflammation-related condition that can create uncomfortable symptoms and headache pain. Here, we explore what causes sphenoid sinusitis and how to deal with it
2) There is an incusion cyst filling 50% of the volume of the left sphenoid sinus and there is mild right sphenoid sinusitis. all other paranasal sinuses appear adequately aerated and non acute. 3) There is no calvarial fracture. currently attempting to locate ENT Specialist in Tallahassee Fl. Please explain how serious. Repl An anterior clinoid mucocele, known to be extremely rare, can lead to visual complications due to its proximity to the optic nerve. We report a patient who developed visual disturbance due to an anterior clinoid mucocele. Interestingly, the anterior clinoid mucocele coexisted with a sphenoid sinus mucocele
Sphenoid sinus mucocele is a rare condition, comprising 1-2% of all paranasal sinuses mucoceles Sphenoid sinus mucoceles are relatively rare, representing 1% of all paranasal sinus mucoceles.[3 4] They usually start unilaterally, but by the time of presentation, the entire sphenoid sinus complex may be opacified and expanded with thinning of its bony walls Sphenoid sinus mucocele is an infrequent but well-recognized entity in sinus pathology. The symptoms produced by it are related to the anatomical surroundings of the sphenoid sinus. We describe a case of sphenoid sinus mucocele presenting with ipsilateral oculomotor nerve palsy 10 years after endoscopic sphenoidotomy Mucoceles are benign, encapsulated, expansile, locally destructive masses within cavities, filled with mucous and lined by epithelium. Only 1-2% of all paranasal sinus mucoceles are located in the sphenoid sinus Mucocele of the Sphenoid Sinus published on Sep 1946 by Journal of Neurosurgery Publishing Group
The sphenoid sinus, the less commonly involved, represents 1% to 8% of the paranasal mucoceles (5). Despite it is benign, its expansive nature may slowly cause erosion of the paranasal sinuses osseous limits by compression and consequent osseous reabsorption, which leads to commitment of adjacent structures (6) Sphenoid sinusitis resolved in all seven cases. The formation of sphenoid sinusitis/mucocele is related to the size of the sphenoidotomy, frequency of postoperative nasal care, and foreign body accumulation. Early surgical drainage is necessary in patients with rhinosinusitis/mucocele refractory to medical management to prevent ascending. We report an extremely rare case of a fungus ball within a mucocele of the sphenoid sinus and infratemporal fossa. Case report A 62-year-old woman with a benign medical history, including no history of allergies, was referred for evaluation of a mass lesion in the left sphenoid sinus and infratemporal fossa
The rareness of paranasal sinus mucocele in children especially sphenoid occurrence prompted the authors to discuss the etiology, radiological imaging findings and the role of endoscopic endonasal sphenoidotomy.Keywords: Sphenoid sinus, Mucocele, Children [eastjmed.org Sphenoid Sinus Mucoceles.

The patient was successfully managed with incision and drainage. Although transsphenoidal hypophysectomy is a common operation, this particular complication appears to be rare or at least under-reported..
Sphenoid sinus mucocele is a rare occurrence. Since the original description by Berg in 1889, 1 81 cases had been reported worldwide in the literature by 1970. Etiology is controversial. Hypotheses have been advanced of slow and progressive accumulation of secretions due to obstruction of the draining ostium caused by chronic sinusitis, 1,2-4 cystic dilatation of glandular mucous cells, 3,5. When the contents of the cavity are purulent, it is considered to be a suppurating mucocele or a pyocele. 1, 2 The sphenoid sinus, which may vary in capacity from . . . Funding and Disclosure Mucoceles of the sphenoid or posterior ethmoid sinuses usually behave in a similar manner. Because of the thinness of surrounding bone and the proximity of vital structures, these lesions can expand aggressively at a clinically alarming rate. Presenting symptoms vary but characteristically include headache and ocular disturbance

Presenting symptoms vary but characteristically include headache and ocular disturbance. Careful radiologic evaluation helps in the correct assessment of.
Purpose: Mucoceles of the sphenoid sinus represent 1-2% of all paranasal sinus mucoceles. The aim of this paper is to report our experiences in patients with mucoceles of the sphenoid sinus. Patients and method: In a period of 4 years, we observed six patients in whom a mucocele of the sphenoid sinus was suggested pre- or intraoperatively. Symptoms and signs included headache, visual loss. Sphenoid mucocele comprises 1-2% of all mucoceles. The first case of sphenoid mucocele was described by Berg in 1889. Sinc Mucoceles of the sphenoid are usually seen in 4 th decade of life, and usually does not have any sex predilection. Sphenoidal mucocele have varied presentations because of adjacent nonbony structures, namely first six cranial nerves, the carotid arteries, the The paranasal sinuses mucoceles are benign expansive cystic lesions that occur rarely in the sphenoid sinus and contain mucous material, enclosed by cylindrical pseudostratified epithelium . The treatment is surgical and currently, endonasal endoscopic method is the modality of choice  A mucocele of the sphenoid sinus caused persistent headache and destroyed the pituitary fossa before it was diagnosed and treated surgically via the transnasal route. The possible absence of clinical leads to the nature of this condition, and the importance of establishing a tissue diagnosis with destructive lesions in this area, are emphasized. Case description. This patient who presented with a left sphenoid sinus mucocele, has undergone spontaneous resolution and re-aeration of the left sphenoid sinus three months after the CT scan revealed complete opacification of the left sphenoid sinus
ALTHOUGH mucoceles of the frontal and ethmoidal sinuses are not unusual, they are rarely found in the maxillary and sphenoidal sinuses (1, 4, 6, 10, 12, 13, 23, 27, 30). Some authors suggest that mucoceles of the maxillary antrum never (26, 27) or rarely ever occur (4, 10) Mucoceles are benign, encapsulated, expansible, locally invasive masses within a paranasal sinus filled with mucus and lined by epithelium. Sphenoid sinus mucoceles are relatively rare, accounting for only 1% of all paranasal sinus mucoceles. Usually presenting with headache but can rarely result in visual defect, diplopia and at times, ptosis CONCLUSION: Sphenoid sinus mucocele is a rare condition. In this study, radiation to the head and neck appeared to be a predisposing factor, and eye symptoms were the commonest presentation. Endoscopic sinus surgery is a safe and effective treatment modality Chole, RA 1978, ' Sphenoid sinus mucocele simulating a malignancy ', Annals of Otology, Rhinology & Laryngology, vol. 87, no. 4, pp. 586-587. https://doi.org/10.1177. Sphenoid sinus mucocele is the most rarely afflicted sinus and comprise 1-2% of all paranasal sinuses mucoceles, 1 but when it is afflicted many vital complications may occur since several important structures including the dura, pituitary gland, optic nerve, cavernous sinus, internal carotid artery and cranial nerves (oculomotor, trochlear.
Mucoceles of the sphenoid sinuses are uncommon; 60 cases have been reported in the world literature to date. Signs and symptoms are caused by local expansion of the mucocele and include headache (the most common symptom), ocular field deficits, external ophthalmoplegia (particularly the sixth cranial nerve), and proptosis. Radiologic correlation in the form of plain films and polytomography is. Sphenoid Sinus Mucocele. Posted by Rathachai Kaewlai, M.D. Fig. 1: Axial unenhanced CT image shows opacification of the left sphenoid sinus due to a mass (arrow) causing slight expansion of the sinus. Some parts of the sinus wall are thin and some are thick. Fig. 2: Coronal T2W GRE MR image show the mass to be very hyperintense Sphenoid sinus mucocele may be asymptomatic. It is commonly discovered accidentally after CT or MRI of the head and neck region. 35 Patients with sphenoid sinus mucocele may become symptomatic when the mucocele compresses or displaces structures around sphenoid sinus. Clinical symptoms may mimic neoplasm The diagnosis of mucocele of the sphenoid sinus is usually made at autopsy or at surgery, when a transdural procedure often leads to a fatal meningitis. In the majority of reported cases, radiologic examination was not carried out; in those in which such examination was performed, it was inadequate or the findings were not appreciated and sphenoid sinuses exit into the nasal cavity by way of ostia; the ethmoid sinuses contain multiple tiny air pockets (air cells) and drain via the gaps between these cells. Also called sinus cysts, mucoceles grow slowly and can also affect the surrounding bone. Because a mucocele will continue to grow in size, it should be endoscopically.
UNLABELLED: Mucoceles of the sphenoid sinnus are rare. 140 cases have been reported in the literature. PURPOSES: We review a case and discuss: 1) pathophysiology and diagnosis of mucoceles; 2) etiologies, anatomical variants, clinical manifestations and treatment of sphenoidal mucoceles An Onodi cell is a posterior ethmoid (sphenoethmoidal) cell that extends superior and often lateral to the sphenoid sinus (Figures 21, 22). Horizontal septations within the sphenoid sinus seen on CT represent an Onodi cell, with the Onodi cell being the posterolateral cell at the level where the horizontal septation is seen (Figures 21, 22). It. The most common causes of mucoceles are chronic infection, allergic sinonasal disease, trauma and previous surgery. The most common location of a mucocele is the fronto-ethmoidal sinus, followed by the sphenoid sinus. The least common location is the maxillary sinus. On the left a patient with an uncommon cause of a mucocele Sphenoid sinus mucocele penetrating to the orbit, anterior and middle cranial fossae and parapharyngeal space: a case report Sphenoid Ridge Lymphoplasmacyte-rich Meningioma Sphenoidal Sinus Mucocele presenting with acute visual loss in a scuba dive
Results Six patients diagnosed with fungal mucoceles of the sphenoid sinus were seen at UCLA Medical Center from 1980-1999. Endoscopic intranasal sphenoid sinusotomy was performed on 4 patients and a transseptal or transantral approach to the sphenoid sinus was used on the remaining 2 patients Mucocele. Sphenoid sinus mucocele compromises 1-2% of all paranasal sinuses mucoceles. 6 The pathophysiology of mucocele is retention of mucoid secretion within the sinus, leading to thinning, distension and erosion of the sinus bony walls. The most common location is the frontal sinus then the anterior ethmoidal sinus .Sphenoid sinus. sphenoid sinus mucocele in the differential diagnosis is an indication for surgical approach by the intranasal route. This is a much safer approach than the sub-frontaltranscranialtechnique, asit eliminates openingthedurato apossiblyinfected sphenoid sinus (Lundgren and Olin, 1961; Norman and Yanagisawa, 1964). sphenoid sinus mucocele in a North African patient treated some years before with radiotherapy for a nasophary-ngeal carcinoma (NPC). We extend the literature review about this infrequent finding, of which head and neck surgeons should be aware. Key words: Mucocele, sphenoid sinus mucocele, nasopharyngeal carcinoma, radiotherapy, North African August 26, 2019. We continue our series of short videos showing radiographic findings so you can learn more about a wide array of pituitary disorders and also see how an MRI is interpreted. This MRI was thought to be of a pituitary tumor, but it turns out it is of a sphenoid sinus mucocele, which is a cyst that contains mucous material
Sphenoid Sinus Mucocele. Angela Donaldson and Lee A. Zimmer. History. A 46-year-old black woman arrived at the clinic with a 3-month history of headaches and visual changes. The patient described the headaches as localized to the left frontal region, worsened by lying supine, and constant in nature The etiology of sphenoid sinus mucocele remains unknown, but three pathogenic mechanisms have been formulated: submuco-sal edema, obstruction of the secretory duct, and obstruction of the sphenoid sinus ostium. Several contributing factors can be cited: allergic rhinitis, chronic sinusitis, polyposis, etc. (5). Anothe Mucocele of sphenoid sinus is a rare cause of oculomotor nerve palsy. A 59-year-old male presented with a 2-week history of sudden ptosis of his right eyelid and right internal ophthalmoplegia. Laboratory examination and radiological evaluation revealed mucocele of the right sphenoid sinus with diabetes and chronic rhinosinusitis
On CT scan diagnosis was given as Sphenoid mucocele on right side secondary to fungal sinusitis. So based on clinical features & imaging study this condition was provisionally diagnosed as Sphenoid mucocele with optic neuritis. Functional endoscopic sinus surgery was done and pus was drained under general anaesthesia A sphenoid sinus mucocele can produce symptoms of sub occipital headaches and vision loss. Mucoceles are generally sterile although occasionally they can get infected and then they cause pain. It is possibly that your headaches and vision problems are related to the mucocele in the sphenoid sinus
Sinus cyst: A common finding in sinus fils or CT scan. Often seen in allergic patients. Mucocele (mucosal cyst) in sinus can be seen in 20% of asymptomatic normal patients. Mucosal edema is consistent with allergic patient and does not require surgery unless there are repeated sinus infection Cluster-Like Headache Secondary to Sphenoid Sinus Mucocele Contact Us Â©2020 Clusterbusters | The view, opinions, conclusions and other information expressed are not given or endorsed by ClusterbustersÂ® unless otherwise indicated by an authorized representative independent of this message Mucoceles are capsulated and locally invasive benign lesions expanding from paranasal sinuses, lined with respiratory epithelium. Mucoceles are commonly seen in the frontal sinuses. Sphenoid sinus mucoceles are rare [1-3]. Mucocele of the sphenoid sinus can cause bony erosion in the orbit apex, which can be seen preferably with CT scan of orbit.
