Neural stem cell delivery of an oncolytic adenovirus in newly diagnosed malignant glioma: a first-in-human, phase 1, dose-escalation trial.
Malignant glioma is the most common and lethal primary brain tumour, with dismal survival rates and no effective treatment. We examined the safety and activity of NSC-CRAd-S-pk7, an engineered oncolytic adenovirus delivered by neural stem cells (NSCs), in patients with newly diagnosed high-grade glioma.</AbstractText>T...

A Case of Sellar/Suprasellar Neurocysticercosis Mimicking a Craniopharyngioma.
Neurocysticercosis (NCC) commonly presents with seizures in developing countries such as Nepal. It may also present with raised intracranial pressure due to obstructive hydrocephalus when cyst is located in the fourth ventricle or foramen of Monro. There are four main stages of NCC (1) Vesicular, (2) Colloidal vesicula...
