We report a rare instance of primary pulmonary angiosarcoma presenting as a large solitary mass in the left upper lobe with mediastinal invasion. In particular, we emphasize the magnetic resonance (MR) imaging features, which included a markedly heterogeneous pattern consisting of hyperintense areas scattered throughout a background of intermediate signal intensity, rendering the lesion a cauliflower-like appearance especially on T2-weighted images. Being unreported so far in primary pulmonary angiosarcomas, these distinct MR imaging findings may be helpful in the differentiation of these neoplasms from lung cancers.
我们报告了一例罕见的原发性肺血管肉瘤，表现为左上叶的一个巨大孤立性肿块并侵犯纵隔。特别是，我们强调了磁共振（MR）成像特征，其包括一种明显不均匀的模式，由散在分布于中等信号强度背景中的高信号区域组成，使病变呈现出菜花状外观，尤其是在T2加权图像上。这些独特的MR成像表现迄今在原发性肺血管肉瘤中尚未见报道，可能有助于将这些肿瘤与肺癌相鉴别。
