Sonography of the popliteal space was performed in 28 patients with a history of a popliteal mass, verified by physical examination in all but 7 patients. The final diagnosis was established by needle biopsy or surgery. Three main types of lesions were found sonographically. A thin-walled echo-free cyst was present in 16 patients. The diagnosis in all of these cases was Baker's cyst. Two patients had a mixed cystic and solid lesion, which was found to be a Baker's cyst, with a loose body in 1 case and a soft-tissue sarcoma with hematoma in the other. Three patients showed solid lesions subsequently diagnosed as an old rupture of the semimembranosus muscle, lipoma, and soft tissue sarcoma. Sonography was normal in the 7 patients without clinical evidence of a popliteal mass. Sonography of popliteal masses is useful to distinguish benign cysts from other lesions.
对28例有腘窝肿块病史的患者进行了腘窝超声检查，除7例患者外，其余均经体格检查证实。最终诊断通过针吸活检或手术确定。超声检查发现了三种主要类型的病变。16例患者存在薄壁无回声囊肿。所有这些病例的诊断均为贝克囊肿。2例患者有混合性囊性和实性病变，其中1例为贝克囊肿伴游离体，另1例为软组织肉瘤伴血肿。3例患者表现为实性病变，随后诊断为半膜肌陈旧性破裂、脂肪瘤和软组织肉瘤。7例无腘窝肿块临床证据的患者超声检查正常。腘窝肿块的超声检查有助于区分良性囊肿与其他病变。
