A nine year old girl presented with nausea vomiting and hydrocephalus. Imaging studies demonstrated a large right thalamic mass with areas of cystic change or necrosis. Sections of resected material showed perivascular pseudorosettes, necrosis, endothelial proliferation, numerous mitoses, densely cellular areas and numerous foci with a clear-cell morphology. This case is used to illustrate the features of anaplastic ependymomas and to discuss the relationship of the histologic features to prognosis.
一名9岁女孩出现恶心、呕吐和脑积水症状。影像学检查显示右侧丘脑有一个大肿块,伴有囊性变或坏死区域。切除组织切片显示有血管周围假菊形团、坏死、内皮细胞增生、大量有丝分裂、细胞密集区域以及许多具有透明细胞形态的病灶。该病例用于阐述间变性室管膜瘤的特征,并讨论组织学特征与预后的关系。
