[Atypical cerebellar neurocytoma resembling a hemangioblastoma. A case report].
Through August 2013, 105 cases of intracranial extraventricular neurocytoma (EVN) had been described; 6% were located in cerebellum and 22% were atypical EVN. A rare morphologic form of neurocytoma, atypical EVN has had only 24 cases reported to date. Its prognosis is poorer than the typical central neurocytoma. This case report describes an atypical cerebellar EVN, a form that has not been reported yet, hence the interest of this article. We emphasise its cystic nature and mural nodule, in an infrequent presentation. EVN are low-incidence tumours that we need to take into consideration when making the differential diagnosis of cystic cerebellar lesions with mural nodule. Given that the prognosis of atypical EVNs depends on the atypical nature and on the grade of resection, medical follow up has to be more constant, due to the greater degree of recurrence.
