好久没看神经病理的病例了，一看就是没思路。待学习

 胶质细胞瘤，（肥胖细胞型）？

 今天晚上听讲座学习再看

 再来几个低倍视野看看就好了

 考虑室管膜下瘤，WHO I 级。

 GFAP（-），患者无结节硬化。还需要考虑哪些肿瘤？

This is WHO grade I subependymal giant cell astrocytoma, which does not have to be associated with tuberous sclerosis in the patient at the time of diagnosis. One differential diagnosis is gangliocytoma, but I doubt it is. Is there perivascular inflammation, necrosis or mitotic figure? Is there formation of eosinophilic granular bodies?

 学习了

 胶质瘤，左侧脑室占位，应考虑室管膜下巨细胞星形细胞瘤。不是所有的室管膜下巨细胞星形细胞瘤都发生在结节硬化的患者吧？
