A case of osteochondroma developed in the femoral neck causing sciatic nerve irritation

Abstract

A 37-year-old man presented with a 4-year history of left hip joint and buttock pain. Radiographs, computed tomography, and bone scintigraphy revealed an osteochondroma on the postero-inferior aspect of the left femoral neck. It was thought that this lesion caused sciatic nerve pain such as the above hip and buttock pain.

Surgical resection was performed. Postoperatively, the patient reported improvement in buttock pain. Pathologic findings revealed a definitive diagnosis of osteochondroma. Only five literatures reports about osteochondroma around the hip joint causing sciatic nerve pain previously. Therefore, our case of osteochondroma on the femoral neck with sciatic nerve pain was considered to be rare.
