A 45-year-old male presented with sudden onset of severe headache. Computed tomography and magnetic resonance imaging demonstrated an irregularly enhanced suprasellar mass with intratumoral and subarachnoid hemorrhage. The mass was removed in two operations. Histological examination of the tumor revealed pilocytic astrocytoma. The relatively rich vascularity and perivascular tumor cell proliferation observed in this benign lesion were probably the causes of this extremely rare association.
一名45岁男性突发剧烈头痛。计算机断层扫描和磁共振成像显示鞍上有一不规则强化肿块，伴有瘤内及蛛网膜下腔出血。该肿块分两次手术切除。肿瘤组织学检查显示为毛细胞型星形细胞瘤。在这个良性病变中观察到的相对丰富的血管和血管周围肿瘤细胞增殖可能是这种极其罕见关联的原因。
