The imaging investigations in six patients with alveolar soft part sarcoma (ASPS) are reviewed. Five patients presented with a pelvic or lower limb mass and one with haemoptysis from pulmonary metastases. Magnetic resonance imaging (MRI), CT, Doppler US and angiography studies demonstrated the highly vascular nature of this rare tumour and the frequent occurrence of pulmonary and intracranial metastases. Previously unreported Doppler US and MR evidence of multiple enlarged vessels and high blood flow within primary and secondary ASPS tumours is emphasized. Imaging is of considerable importance both for pre-operative localization and long term surveillance of this slow growing but invariably disseminating tumour.
回顾了6例肺泡软组织肉瘤（ASPS）患者的影像学检查情况。5例患者表现为盆腔或下肢肿块，1例因肺转移出现咯血。磁共振成像（MRI）、CT、多普勒超声和血管造影研究显示了这种罕见肿瘤的高血管性以及肺和颅内转移的频繁发生。强调了先前未报道的关于原发性和继发性ASPS肿瘤内多条血管扩张和高血流的多普勒超声和磁共振证据。影像学对于这种生长缓慢但总是发生播散的肿瘤的术前定位和长期监测都具有相当重要的意义。
