enchondroma
An enchondroma is a cartilage cyst found in the bone marrow. Typically, enchondroma is discovered on a X-ray scan. Enchondromas have a characteristic appearance on Magnetic Resonance Imaging (MRI) as well. They have also been reported to cause increased uptake on PET examination. ==Presentation== Enchondroma is a type of benign bone tumor that originates from cartilage. The exact etiology of it is not known. An enchondroma most often affects the cartilage that lines the inside of the bones. The bones most often involved with this benign tumor are the miniature long bones of the hands and feet. It may, however, also involve other bones such as the femur, humerus, or tibia. While it may affect an individual at any age, it is most common in adulthood. The occurrence between males and females is equal. It is not very likely that the enchondroma will grow back in the same spot; the rate is less than ten percent.
