软组织肉瘤约占恶性肿瘤的1%,软组织腺泡状肉瘤(Alveolar Soft-Part Sarcoma)为最不常见的软组织肉瘤之一,作者报告了11例。男6例,女5例,平均年龄27岁,发生于大腿者4例,前臂2例,臂部、腹直肌和颞下窝各1例。5例发生转移,2例复发。传统放射学检查,2例出现中央区点状钙化,4例直接侵犯邻近骨骼。非增强CT检查,4例显示较肌肉密度为低的改变;5例增强检查与5例血管造影者显示肿瘤明显强化及多血管性。增强CT检查发现3例为等密度,2例为高密度(与周围肌肉相比),2例出现中央区低密
Soft tissue sarcomas account for about 1% of malignant tumors. Alveolar Soft-Part Sarcoma is one of the least common soft tissue sarcomas. The authors reported 11 cases. 6 males and 5 females, with an average age of 27 years, occurred in 4 cases in the thigh, 2 cases in the forearm, 1 case in the arm, rectus abdominis, and infratemporal fossa. Metastasis occurred in 5 cases and recurrence occurred in 2 cases. In traditional radiological examination, punctate calcification occurred in 2 cases in the central area, and 4 cases directly invaded neighboring bones. On non-enhanced CT scans, 4 patients showed a lower change in muscle density; 5 patients with enhanced examination and 5 patients with angiograms showed significant tumor enhancement and multivascularity. The enhanced CT examination revealed that 3 cases had equal density, 2 cases had high density (compared with surrounding muscles), and 2 cases showed low density in the central area.
