摘要
目的分析股骨颈骨样骨瘤的临床及MRI表现特点、误诊和漏诊的原因,进一步提高其诊断的准确性。方法回顾性分析了17例手术病理证实的股骨颈骨样骨瘤的临床和MRI表现特点。结果4例具有典型的夜间疼痛加重,13例为髋关节的疼痛,疼痛持续时间为1月～24月,平均9.2月。14例临床诊断为髋关节炎,3例诊断为股骨颈骨髓炎;MRI显示瘤巢10例,股骨颈髓腔水肿17例,关节肿胀17例,其中3例MRI诊断为骨样骨瘤,14例MRI诊断为髋关节炎,诊断的准确率为17.64%。结论由于股骨颈骨样骨瘤的临床表现不典型,瘤巢小而难以被发现且髋关节积液明显,是MRI误诊、漏诊的原因,提高对其的认识有助于及时的诊断和治疗。
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.
