Abstract

Objective To analyze clinical character and the MR imaging features of osteoid osteoma in the femoral neck and the reason of misdiagnosis. Methods The clinical and MR imaging data of 17 cases of osteoid osteoma in femoral neck which were proved by surgical pathology were collected and analyzed retrospectively. Results Only 4 cases had the typical symptom which consists of pain that worsens at night. Duration of pain was 1 to 24 monthes (mean 9.2 monthes). Fourteen cases were diagnosed clinically as coxarthritis, the rest 3 cases as osteomyelitis of femoral neck. In MR imaging, nidus was demonstrated in 10 cases, and 17 cases had the associated marrow oedema in femoral neck and hip-joint effusion. Three cases were diagnosed correctly, and 14 cases were misdiagnosed as coxarthritis in MR imaging. Conclusions The clinical symptom of osteoid osteoma in femoral neck was atypical. Unable to demonstrate the small nidus and the associated joint effusion were the reasons of misdiagnosis in MR imaging.
