Awake craniotomy in an adolescent patient with an extraventricular neurocytoma
Outcome MRI was performed at 3, 12, 24 and 36 months after surgery and showed no evidence of residual tumour and no recurrence (figure 4). Since GTR was obtained and no atypical elements were found on histological examination, the patient did not undergo radiotherapy. Discussion Extraventricular neu...

Summary: | Outcome MRI was performed at 3, 12, 24 and 36 months after surgery and showed no evidence of residual tumour and no recurrence (figure 4). Since GTR was obtained and no atypical elements were found on histological examination, the patient did not undergo radiotherapy. Discussion Extraventricular neurocytoma (EVN) is a rare tumour with similar histopathological characteristics of CNC that occurs in lateral ventricles.2 Usually, these tumours are large lesions with significant overlap in imaging appearance with other brain neoplasms. [...]it is difficult to make an accurate preoperative diagnosis. According to 2016 and 2021 WHO classification, EVN is generally considered as a grade-2 tumour, except for those with atypical histological features that include increased mitotic figures, focal necrosis, endothelial cell proliferation and/or a Ki-67 index of>2%. Diagnosis of low-grade tumour should not be made only by preoperative MRI findings, because radiological features of EVN overlap with those of more aggressive primary brain tumours. [...]we planned an awake craniotomy with continuous language and cognitive function monitoring, aiming to GTR while prevent postoperative deficit. |
