OBJECTIVE To reduce postoperative hydrocephalus following surgery in the region of the fourth ventricle. METHOD/TECHNIQUE: We describe the use of a conventionally placed lateral ventricular catheter to facilitate anterograde ventricular irrigation during surgery in the region of the fourth ventricle. This technique offers a safe alternative to more conventional approaches to fourth ventricular ...

We report the case of a 57-year-old man with a known history of antineutrophil cytoplasmic antibody-positive Wegener granulomatosis with initial involvement of the upper and lower respiratory tract. MR imaging of the brain was performed because of new onset CNS symptoms (nausea, altered mental status). The images revealed a mass in the fourth ventricle. The mass diminished in size after systemi...

Epidermoid tumors arising from the fourth ventricle are uncommon. Although they may grow to an enormous size in a very critical location, the majority of patients do not have the explosive symptoms and neurologic findings common to most fourth-ventricular tumors. We present one confirmed case and one highly suggestive case of epidermoid tumor of the fourth ventricle. Both were evaluated by MR i...
