Enchondroma Radiology

Differentiating between an enchondroma vs low-grade chondrosarcoma can be challenging 1. Features that should raise suspicion of low-grade chondrosarcoma include a size over 5-6 cm, pain, and endosteal scalloping. Due to the size and pain, a bio.. Case Discussion. Overall features matching with a sizable distal femoral non-aggressive chondrogenic lesion, suggestive of a low-grade chondral lesion, almost certainly an enchondroma. Enchondroma is a benign cartilaginous lesion of the medullary cavity. Most enchondromas are asymptomatic and incidentally noted Enchondroma. General considerations. Benign cartilaginous tumor. Develops in the medullary cavity. Usually solitary, although they can occur as multiple lesions in syndromes to be discussed. Arise from ectopic rests of hyaline cartilage. Occur mostly in 2nd to 3rd decade. Most common site is small bones of the hands and feet The study of Herget et al. 28 showed that the time between the initial diagnosis of enchondroma and the diagnosis of malignancy varied between 6 months and up to 30 years. This indicates that enchondroma and ACT lesions might profit from a lifelong radiological follow-up Enchondroma is a benign neoplasm of the medullary canal com posed of mature hyaline cartilage.Enchondroma is one of the most common osseous neoplasms, representing 12-24% of all benign bone tumors and 3-10% of all bone tumors [1, 2].Of benign chondroid lesions, it is second only to osteochondroma in frequency [1, 2].Intramedullary chondrosarcoma is also relatively common, accounting for 20-27%.

Enchondroma. Enchondroma is a benign intramedullary tumor consisting of hyaline cartilage. It is the most common tumor involving the bones of the hand, accounting for up to 50% of all primary tumors in this anatomic region [5, 6].Enchondroma occurs most commonly in the proximal phalanges, followed by the metacarpals and middle phalanges Enchondroma and chondrosarcoma are both common osseous neoplasms. Enchondroma represents 12-24% of all benign bone tumors, and 3-10% of all bone tumors; chondrosarcoma accounts for 20-27% of primary bone sarcomas, and 8-17% of all bone tumors. 1 Distinction between benign and malignant chondroid neoplasms is essential for correct patient.

  3. Enchondroma with pathologic fracture. Left: There is a non-displaced fracture through the base of the proximal phalanx of the 4th toe (white arrow). Right: A well-defined, slightly expansile, lytic lesion is seen in the proximal phalanx (white circle) through which the fracture has occurred
  4. An enchondroma is a type of noncancerous bone tumor that begins in cartilage. An enchondroma most often affects the cartilage that lines the inside of the bones. It often affects the tiny long bones of the hands and feet. It may also affect other bones such as the femur (thighbone), humerus (upper arm bone), or tibia (one of the two lower leg bones)

Enchondroma. Enchondroma is a benign cartilage tumor. Frequently it is a coincidental finding. In the phalanges of the hand it frequently presents with a fracture. It is the most common lesion in the phalanges, i.e. a well-defined lytic lesion in the hand is almost always an enchondroma Incidental enchondroma of the femur is seen in 3% of the routine MR knee examination ( 10 times higher than autopsy series). The other common side are proximal tibia and proximal fibula. The incidence of higher prevalence of enchondroma on imaging as compared to autopsy series is due to increase sensitivity of MRI Enchondroma protuberans: rare, exaggeratedly eccentric enchondroma resembling osteochondroma radiologically (Hum Pathol 1982;13:734) Radiology description.

  1. Enchondroma is a benign indolent intramedullary hyaline cartilage neoplasm. Accounts for 10% of all benign osseous tumors. Limited growth, most lesions are less than 5 cm in maximal dimension. Bones grow from a cartilaginous growth plate that gradually lengthens and turns into bone as it lengthens. An enchondroma can be thought of as an island.
  2. Bone infarction is a term used to refer to osteonecrosis within the metaphysis or diaphysis of a bone. Necrosis is a type of cell death due to irreversible cell injury, which can be recognized microscopically by alterations in the cytoplasm (becomes eosinophilic) and in the nucleus (swelling, pyknosis, karyorrhexis, karyolysis)

  4. Enchondroma is a type of benign bone tumor belonging to the group of cartilage tumors. There may be no symptoms, or it may present typically in the short tubular bones of the hands with a swelling, pain or pathological fracture. Diagnosis is by X-ray, CT scan and sometimes MRI. Most occur as a less than three centimetre size single tumor. When several occur in one long bone or several bones.
  5. Definition / general. Usually asymptomatic or pain due to pathologic fracture. Age 20 - 49 years, no gender preference. May be due to displaced growth plate. Sites: small bones of hands and feet (rare in thumb or ribs) 70% solitary; 30% multiple. Multiple enchondromas: may produce severe deformities; associated with chondrosarcomatous.

Contrary to enchondroma, tubular bone (GT) enchondroma usually requires cross-sectional imaging like CT or MRI. CT is the imaging method of choice to detect chondroid mineralisation when it is very subtle on radiographs [23] Enchondroma. Enchondroma (en-kon-DRO-ma) is a type of benign (noncancerous) tumor that begins in the cartilage found inside the bones. Enchondromas rarely cause pain or other symptoms, so most remain undiagnosed until x-rays are taken for an unrelated injury or condition. In the majority of cases, enchondromas do not require treatment Enchondroma is the most frequently encountered tumour. Since the vast majority of enchondromas are asymptomatic, they are typically discovered as incidental findings or along with a pathologic fracture. The authors propose a pictorial review to illustrate the imaging features of cartilaginous bone lesions of the hand and their specificities.

Actually, that is exactly what the patient presented above has been going through, he has done 4 x-rays of his hand in the last two years, and no changes were noticed since the first one The purpose of this review is to help radiologists confidently diagnose enchondroma and distinguish it from other entities, such as bone infarct, bone graft, and low-grade chondrosarcoma Purpose: To minimize systematic bias and optimize agreement on imaging criteria in order to better define the accuracy of imaging criteria in the diagnosis of grade 1 chondrosarcoma. Materials and methods: Study was IRB-approved and HIPAA compliant; informed consent was waived. Records were reviewed and disclosed 53 cases (38 women, 15 men ages 21-76) which were diagnosed as enchondroma or. The Enchondroma is a common, benign, cartilage forming tumour. They usually occur as a single, asymptomatic lesion. Occasionally patients present with multiple enchondromas which is generally defined as enchondromatosis.

Enchondromas aswell as low-grade chondrosar An enchondroma is a type of benign (noncancerous) bone tumor that originates from cartilage. Cartilage is the specialized, gristly connective tissue from which most bones develop. Cartilage plays an important role in the growth process. There are many different types of cartilage throughout the body An enchondroma is a benign tumor found inside of bone. The typical scenario is that a patient had an x-ray for an injury to a joint, commonly the shoulder, knee, or ankle. While the joint looks normal, an abnormality is seen inside the bone. Often these are completely unrelated to the cause of pain, and one of the most common reasons is an. Six centimeters lesion of the proximal humerus with lobulated contours and very high signal intensity on T2-weighted images with fat suppression ( @2.9 ).

Most expansile, lucent lesions are located in the medullary space of the bone. However, we can further define the location of the lesion by noting its relationship to the physis.

Low-grade chondrosarcoma can be difficult, if not impossible, to differentiate from an enchondroma, which is the primary alternative consideration in the differential diagnosis.

In middle-aged or elderly patients, enchondroma should be differentiated from low-grade chondrosarcoma. Clinical distinctions can be made on the basis of pain, and radiologic distinctions are based on preservation of cancellous bone or adjacent cortex.
