Question

Diagnosis

• A. GCT
• B. Osteochondroma
• C. Osteoid Osteoma
• D. Ewings Sarcoma

Answer 1

The Correct Option is A

In this problem, we are asked to identify the correct diagnosis from a set of options based on an image, which is not visible here. To solve this question, we need to consider the typical characteristics of the listed conditions in the context of radiodiagnosis.

Giant Cell Tumor (GCT): Typically arises at the epiphyseal ends of long bones, often around the knee in young adults. On X-ray, it appears as a lytic lesion.

Osteochondroma: A benign bone growth projecting from the surface of a bone, typically seen in adolescent patients. It shows as a bony outgrowth with a cartilage cap on X-rays.

Osteoid Osteoma: Characterized by a smaller, painful, bone-forming lesion, frequently less than 2 cm in size, seen as a radiolucent nidus surrounded by reactive sclerosis.

Ewing's Sarcoma: A malignant tumor often seen in children and adolescents. Radiographically, it presents as a permeative bone lesion with an onion-skin periosteal reaction.

Given the options and the condition described by the image (which needs evaluation based on the common characteristics if accessible), GCT is the likely diagnosis because it typically presents as a lytic bone lesion in the epiphyseal region of long bones, matching the context and description we can infer from the problem statement.

Thus, based on the characteristic features described, the correct answer is GCT.
