Computed tomography (CT) was performed in six patients with painful soft-tissue masses where sarcoma was suspected. Incisional or excisional biopsy proved all to be extraosseous ganglia. CT delineated the anatomic relationships of the masses. The CT density of four of the ganglia was 18 Hounsfield Units (HU), consistent with that of fluid-filled lesions. Contrast medium did not enhance the lesions on CT. Angiography was performed in four cases and demonstrated hypovascular masses with no vessel displacement. Plain radiographs and technetium bone scintigrams were nonspecific. CT was the best preoperative confirmation of the diagnosis of benign extraosseous ganglia and the best method of localizing the lesions with respect to surrounding bone and soft tissues.
对6例疑似肉瘤的疼痛性软组织肿块患者进行了计算机断层扫描（CT）检查。切开活检或切除活检证实所有肿块均为骨外腱鞘囊肿。CT显示了肿块的解剖关系。其中4个腱鞘囊肿的CT密度为18亨氏单位（HU），与液性病变一致。CT上造影剂未使病变强化。4例患者进行了血管造影，显示为血供少的肿块，无血管移位。平片和骨闪烁显像均无特异性。CT是术前诊断良性骨外腱鞘囊肿的最佳方法，也是确定病变与周围骨骼和软组织关系的最佳方法。
