Osteoid osteoma

Case contributed by Dr Mohammad Taghi Niknejad


Nocturnal right thigh pain.

Patient Data

Age: 12 years
Gender: Male

Increased cortical thickness involving the mid femoral shaft on the medial aspect with associated sclerosis and narrow zone of transition.

There is also focal round lucent/lytic lesion within the center of the sclerotic portion of femur suggestive of nidus of osteoid osteoma.

Case Discussion

Findings are compatible with right femoral shaft osteoid osteoma.

CT scan is excellent at characterizing the lesion and is the modality of choice. It typically shows a focally lucent nidus within surrounding sclerotic reactive bone. A central sclerotic dot may also be seen.
