血管平滑肌脂肪瘤是临床上最常见的肾脏良性实体肿瘤。血管平滑肌脂肪瘤曾经被认为是一种错构瘤，并且几乎总是通过基于图像的脂肪检测来诊断，现在已知血管平滑肌脂肪瘤由一组异质性肿瘤组成。虽然所有被认为是血管周围上皮样细胞肿瘤，许多显示不同的病理，影像学特征和临床行为。许多类型的血管平滑肌脂肪瘤几乎不含脂肪，尽管是良性的，但有时会逃避术前诊断，这一事实强调了了解这组肿瘤的重要性。这些类型的血管平滑肌脂肪瘤都可以考虑当遇到一个肾脏肿块，这是相对于肾实质高密度平扫CT和T2低信号，反映了他们的主要平滑肌成分的特点。我们回顾了最近的进展，并提供了一个血管平滑肌脂肪瘤的放射学分类，帮助医生了解各种类型，并学习如何诊断和管理他们。
Angiomyolipoma is the most common benign solid renal neoplasm observed in clinical practice. Once thought to be a hamartoma and almost always diagnosed by the imaged-based detection of fat, angiomyolipomas are now known to consist of a heterogeneous group of neoplasms. Although all are considered perivascular epithelioid cell tumors, many display different pathology, imaging features, and clinical behavior. The importance of understanding this group of neoplasms is emphasized by the fact that many types of angiomyolipoma contain little to no fat, and despite being benign, sometimes escape a pre-operative diagnosis. These types of angiomyolipomas can all be considered when encountering a renal mass that is both hyperattenuating relative to renal parenchyma on unenhanced CT and T2-hypointense, features that reflect their predominant smooth muscle component. We review recent developments and provide a radiological classification of angiomyolipomas that helps physicians understand the various types and learn how to both diagnose and manage them.
