I think WHO grade I dysembryoplastic neuroepithelial tumor (DNT) is the most likely diagnosis, but one would like to see isolated floating neurons in the microcysts in addition to the small oligodendrocyte-like cells and neuropil-like fibrillary matrix. A differential diagnosis is pilocytic astrocytoma, which could look like oligodendroglioma focally. However, I do not see the characteristic features of pilocytic astrocytoma - biphasic growth pattern, microcysts, Rosenthal fibers, and eosinophilic granular bodies. I don't think this is a case of ependymoma or subependymoma or oligodendroglioma.

我考虑可能是WHOI级的DNT（胚胎发育障碍的神经上皮肿瘤）。但DNT中除了少突胶质细胞样的小细胞和神经毡样胶质纤维基质外，还应该见到微囊中漂浮的神经元。鉴别诊断是毛细胞型星形细胞瘤，它可以局灶呈少突胶质细胞瘤样。但我并没见到毛细胞型星形细胞瘤典型特征：双极生长方式、微囊、Rosenthal纤维和嗜酸性颗粒小体。不考虑室管膜瘤、室管膜下瘤或少突胶质细胞瘤。

 不像胶质瘤,如果是倾向少突,

另外考虑促纤维增生型髓母,但年龄大了

考虑可能性最大的:DNT

能有影像学资料更好!
