Pleomorphic xanthoastrocytoma (PXA) has been considered as a low grade tumor of adolescents and young adults. Although this tumor often shows cystic component, the hemorrhage within the cyst is extremely rare. The authors report a rare case of cystic PXA with a hemorrhage within the cyst and the mural nodule in the left frontal lobe. A 64-year-old male presented with a week history of the right side hemiparesis. After gross total resection of the tumor, the patient was fully recovered from neurological deficit. It is suggested that this typically benign tumor could be presented with hemorrhage, causing a rapid neurological deterioration. Prompt surgical intervention, especially total removal of the tumor can provide an excellent functional recovery.
多形性黄色星形细胞瘤（PXA）被认为是青少年和年轻成年人的低级别肿瘤。尽管这种肿瘤常表现出囊性成分，但囊内出血极为罕见。作者报告了一例罕见的左额叶囊性PXA病例，其囊内有出血及壁结节。一名64岁男性出现右侧偏瘫一周病史。肿瘤全切术后，患者神经功能缺损完全恢复。提示这种典型的良性肿瘤可能出现出血，导致神经功能迅速恶化。及时的手术干预，尤其是肿瘤全切可带来良好的功能恢复。
