Neurocytoma
Published in Dongyou Liu, Tumors and Cancers, 2017
Neurocytoma (commonly known as central neurocytoma or CN) is a neuronal and mixed neuronal–glial neoplasm that typically arises from the neuronal cells of the septum pellucidum, the third ventricle, and the lateral ventricles. Neurocytoma is a WHO Grade II tumor with an MIB-1 labeling index (MIB-1 LI) of <2% that may grow inwards into the ventricular system, forming interventricular neurocytoma and leading to blurred vision and increased intracranial pressure. In addition, there exist some “atypical CNs” with unusual aggressiveness, which demonstrate elevated MIB-1 LI >2% and/or histological atypical features, with increased tendency to spread through the cerebrospinal fluid, causing craniospinal axis dissemination [1,2].

(a) Pre-operative, post-operative and 3-months follow up sagittal, axial and coronal contrast enhanced MRI of a 16-years-old boy operated for an optic-hypothalamic grade II astrocytoma; sub-total resection. (b) Pre-operative, post-operative and 3-months follow up sagittal, axial and coronal contrast enhanced MRI of a 67-year-old man operated for a diencephalic glioblastoma (WHO Grade IV); gross total resection. (c) Pre-operative, post-operative and 3-months follow up sagittal, axial and coronal contrast enhanced MRI of a 46-year-woman operated for a third ventricle colloid cyst; gross total resection. (d) Pre-operative, post-operative and 3-months follow up sagittal, axial and coronal contrast enhanced and FLAIR MRI of a 24-year-man operated for a diffuse diencephalic astrocytoma; gross total resection. (e) Pre-operative, post-operative and 3-months follow up sagittal, axial and coronal contrast enhanced MRI of a 21-year-man operated for an atypical central neurocytoma; gross total resection.
Spontaneous massive intracystic hemorrhage due to cystic hemangioblastoma in a pediatric patient

Spontaneous intracerebral hemorrhage in patients younger than 15 years old is most frequently caused by vascular malformations, especially fistulas or arteriovenous malformations (AVM).12 Central nervous system tumors with bleeding in children are rare and include medulloblastoma, ependymoma, teratoma, central neurocytoma and astrocytoma.13,14
Amenorrhoea and reversible infertility due to obstructive hydrocephalus: literature review and case report*
Published in British Journal of Neurosurgery, 2018
Kimberly Hamilton, Bermans Iskandar
The patient experienced nystagmus that resolved spontaneously within 24 hours. The EVD was clamped for monitoring of intracranial pressures; this was kept in place for 5 days due to persistently elevated ICPs during sleep. She remained asymptomatic, the EVD was removed and the patient discharged home on post-operative day 6. Pathology revealed a central neurocytoma.
