Abstract

Neurocytomas are rare neoplasms, composed of uniform round cells with neuronal differentiation. We report a rare extraventricular neurocytoma (EVN) in a 5-year-old boy who presented with headache and vomiting. His MRI brain showed a vermian mass. The histopathological examination and immunohistochemistry revealed it to be an EVN. We report this patient for the rarity of the condition and the EVN mimicking a medulloblastoma on imaging. This tumor needs to be differentiated from a medulloblastoma as the former has a better prognosis.

摘要

神经细胞瘤是一种罕见的肿瘤，由具有神经元分化的均匀圆形细胞组成。我们报告了一例罕见的脑室外神经细胞瘤（EVN），发生于 5 岁男孩，表现为头痛和呕吐。他的脑部 MRI 显示蚓部肿块。组织病理学检查和免疫组织化学显示为 EVN。我们报告这个病例是因为这种情况非常罕见，而且 EVN 在影像学上类似于髓母细胞瘤。这种肿瘤需要与髓母细胞瘤相鉴别，因为前者的预后更好。
