Neurilemmomas are benign neoplasms presumedly derived from Schwann cells which rarely originate within the central nervous system. Moreover, their intraventricular location has been seldom noticed with less than 30 cases reported worldwide. Here, we add another case study to the record as well as the fifth one in Latin American population. A 16-year-old boy without significant past clinical data debuted with headache and progressive left eye blindness during six months. Neuroimaging scans showed a bulky, multiloculated, intraventricular tumour emerging from the posterior horn of the left lateral ventricle. Microscopically, the lesion put on view the classical schwannian histology: spindle cells arranged in both compact and loosely textured areas. Verocay bodies were not present but vessel hyalinisation, pericellular reticulin, and senescent atypia were observed. The immunoperoxidase reactions were also consistent with neurilemmal differentiation; however, glial fibrillary acidic protein expression was widespread and unexpectedly seen. Traditionally conceived as “nerve sheath tumours” the dual immunophenotype herein demonstrated points to a different histogenetical pathway other than sheer Schwann cell derivation. As previously advised by some authors, neoplastic transformation from a multipotent stem cell may explain the occasional finding of these tumours in unconventional intracranial compartments.

Background: Central neurocytoma’s are typically located in the lateral ventricles and are optimally treated with surgical resection. Surgical entry into the ventricles are associated with a number of complications, including subdural hygroma and shunt-dependent hydrocephalus. Methods: We report a patient who developed acute bilateral uncal herniation from progessively enlarging subdural hygromas following intraventricular tumour resection. Results: A 60-year-old female underwent minimally invasive transcortical transventricular resection of an intraventricular CN. The patient’s postoperative course was complicated by repeated presentations to the emergency department due to persistent and intractable nausea and headaches, without focal neurological deficits. Imaging demonstrated small bilateral subdural hygromas. The patient eventually presented with acute deterioration in her level of consciousness with clinical and radiologic evidence of bilateral uncal herniation, requiring urgent insertion of a subdural drain to treat elevated intracranial pressure (ICP). After insertion of a ventriculoperitoneal shunt, the patient was discharged in stable condition and is currently followed by the multi-disciplinary neuro-oncology team. Conclusions: Bilateral subdural hygroma could mask underlying external hydrocephalus post transventricular surgeries. Patients who are symptomatic from bilateral subdural hygromas after transventricular resection of tumors should be carefully monitored for radiographic or clinical progression, in order to avoid acute deterioration caused by elevated ICP.
