Alveolar soft-part sarcoma (ASPS) is a rare tumour. Certain distinctive clinical and radiological features suggest the correct diagnosis. There is moderate predilection for young women. ASPS almost always arises in skeletal muscle and occurs most frequently in the lower limbs. There is often a long clinical history and a large mass at presentation. Two young females with ASPS presented with very vascular tumours in the thigh, with prominent intra- and extra-tumoural blood vessels. The imaging findings and the existing literature are reviewed.
肺泡软组织肉瘤（ASPS）是一种罕见肿瘤。某些独特的临床和放射学特征提示正确诊断。该病对年轻女性有一定偏好。ASPS几乎总是起源于骨骼肌，最常见于下肢。通常有较长的临床病史，就诊时肿块较大。两名患有ASPS的年轻女性大腿部出现血管极为丰富的肿瘤，肿瘤内和肿瘤外血管明显。本文对影像学表现及现有文献进行了综述。
