The computed tomographic (CT) findings in 118 patients with the diagnosis of leiomyosarcoma were reviewed. The tumor masses visualized in these patients were often quite large; extensive necrotic or cystic change was a frequent finding. Calcification was not observed in these tumors. The liver was the most common site of metastasis in these patients, with marked necrosis of the liver lesions a common finding. Other manifestations of tumor spread included pulmonary metastases, mesenteric or omental metastases, retroperitoneal lymphadenopathy, soft-tissue metastases, bone metastases, splenic metastases, and ascites. The metastatic lesions were often centrally necrotic. Although the CT appearance of leiomyosarcoma is not specific, these findings, when present, suggest consideration of this diagnosis.
回顾了118例诊断为平滑肌肉瘤患者的计算机断层扫描（CT）结果。这些患者中可见的肿瘤肿块通常相当大；广泛的坏死或囊性变是常见表现。这些肿瘤未观察到钙化。肝脏是这些患者最常见的转移部位，肝脏病变明显坏死是常见表现。肿瘤扩散的其他表现包括肺转移、肠系膜或网膜转移、腹膜后淋巴结肿大、软组织转移、骨转移、脾转移和腹水。转移灶常呈中心坏死。虽然平滑肌肉瘤的CT表现不具有特异性，但这些表现一旦出现，提示应考虑这一诊断。
