What is distal femoral enchondroma?

Enchondroma is a solitary, benign, intramedullary cartilaginous tumour occurring most commonly in small bones of hands and feet. Distal femur and proximal humerus are other less common locations. Enchondroma consists of 3-10% of all bone tumours, while they constitute 12-24% of benign bone tumours.

Does enchondroma require surgery?

In the majority of cases, enchondromas do not require treatment. In rare cases, however, multiple tumors may weaken the bone, causing it to fracture. When this occurs, surgery may be needed to remove the tumor and prevent additional fractures.

Can enchondroma become cancerous?

Key points about enchondromas An enchondroma is a type of benign bone tumor that originates from cartilage. It is not cancerous.

What does enchondroma mean?

An enchondroma is a type of noncancerous bone tumor that begins in cartilage. Cartilage is the gristly connective tissue from which most bones develop. Cartilage plays an important role in the growth process. There are many different types of cartilage in the body.

How big is an enchondroma in the distal femur?

There is an irregular sclerotic lesion in the lateral metaphyseal region of the left distal femur measuring 11 x 14 x 11mm. No cortical breakthrough, endosteal scalloping or periosteal reaction. No soft tissue mass. A: Popcorn calcification, suggests chondroid mineralisation. Loading images…

Can a bone fracture be caused by an enchondroma?

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. In rare cases, however, multiple tumors may weaken the bone, causing it to fracture.

Where is the distal end of the femur located?

Distal end of femoral intramedullary rod noted. A: Enchondroma. A: Almost all enchondromas are located in the medullary cavity of tubular bones: small tubular bones of the hands and feet (50%); large tubular bones e.g. femur, tibia, humerus. Distribution of enchondromas.

How does enchondroma affect the hands and feet?

In most cases, enchondromas are not painful and do not cause any symptoms. However, if the tumors appear in the hands or feet, or if there are multiple lesions, the bone can weaken and become deformed. This can lead to pathologic bone fractures and enlargement of the affected fingers.
