摘 要:目的分析腺泡状软组织肉瘤(ASPS)的影像学表现,以提高对该病的认识。方法回顾性分析5例经手术或穿刺病理证实ASPS的影像学特点,重点观察病变边缘、深筋膜完整性、密度/信号、瘤内和瘤周肿瘤血管情况及强化特点等。结果 4例表现为边缘不规则且深筋膜受侵,3例发生于下肢,1例发生于骨盆;1例发生于右肾者边缘亦欠规则。1例行CT检查,平扫表现为低、稍高混杂密度。4例行MR检查,T1WI为稍高信号,T2WI高信号,瘤内及瘤周均可见点条状流空信号影;增强扫描不均匀(1例)或均匀(3例)明显强化,瘤内及瘤周可见肿瘤血管影。5例均接受了手术治疗,3例发生转移(1例确诊时即发生转移,2例术后发生肺或肝脏转移)。结论 ASPS影像学表现具有一定特征,表现为CT平扫呈等/稍高密度,T1WI为稍高/高信号、瘤内及瘤周流空信号影、深筋膜破坏等,但确诊仍需组织病理学。Objective To investigate the imaging features of alveolar sort part sarcoma(ASPS), in order to further improve the understanding of the disease. Methods 5 cases with pathologically(surgery or biopsy) proved ASPS were analyzed retrospectively. Imaging features, including lesion edge, the deep fascia integrity, density/signal, tumor blood vessels in/around the masses and strengthening characteristic, were observed respectively. Results 4 cases were characterized by irregular edge and deep fascia invaded. 3 cases happened in the lower extremities, 1 case happened in pelvis.1 case happened in right kidney also had an irregular edge. CT was performed in 1 case, which showed low, mixed slightly higher density on plain scan. On MRI images of 4 cases, the masses showed hyper intensity on T1-weighted images and high intensity on T2-weighted images. And there were point-strip flow void signal in and around the masses. The masses showed heterogeneous(1 case) or homogeneous( 3 cases) enhancement after contrast. Tumor blood vessels could be seen in and around the masses. 5 cases were underwent surgery treatment, with metastases of 3 cases, 1 case metastasized at presentation, and lung or liver metastases were found after resections in other 2 cases. Conclusion ASPS has certain characteristics, which is slightly high density on CT plain scan, a bit higher/high signal on T1WI, flow void signal in and around the masses and the deep fascia integrity. But the final diagnosis still depends on histopathological examination.
