目的:探讨跟骨肿瘤及肿瘤样病变的影像学特征,提高跟骨病变的影像诊断水平。方法:回顾性分析经手术和病理确诊的30例跟骨病变的影像学表现,其中30例行X射线平片检查,19例平片后不能确诊再行CT检查,3例仍然诊断困难再行MR检查。结果:良性肿瘤10例,恶性肿瘤7例,肿瘤样病变13例;骨囊肿在跟骨体部与前部交界处发生率最高,且有特征性。动脉瘤样骨囊肿有分隔,可有钙化。恶性骨肿瘤骨质破坏明显,往往为全跟骨骨质破坏。硬化缘、骨嵴及破坏区密度对鉴别诊断有意义。结论:X射线平片、CT及MR综合表现结合病变部位,可以对跟骨肿瘤及肿瘤样病变提出准确的影像学诊断和鉴别诊断。
Objective: To investigate the imaging features of calcaneal tumors and tumor-like lesions and to improve the imaging diagnosis of calcaneal lesions. Methods: The imaging findings of 30 cases of calcaneal lesions confirmed by operation and pathology were retrospectively analyzed. Among them, 30 cases were examined by X-ray plain film, 19 cases were plain film and CT scan was not confirmed, and 3 cases were still difficult to diagnose MR examination. Results: 10 cases of benign tumors, 7 cases of malignant tumors, 13 cases of tumor-like lesions; bone cysts in the heel of the body and the front of the junction of the highest incidence, and has characteristics. Aneurysmal bone cysts are separated, may have calcification. Malignant bone tumor destruction of bone is obvious, often the whole calcaneal bone destruction. Sclerosing margin, bone crest and destruction of the density of the differential diagnosis of significance. Conclusion: The combination of X-ray, CT and MR combined with lesion can provide accurate imaging diagnosis and differential diagnosis of calcaneal tumors and tumor-like lesions.
