Communicating hydrocephalus following stereotactic radiosurgery for periventricular meningiomas: illustrative cases.

Background: Stereotactic radiosurgery (SRS) is a well-established option for the management of intracranial tumors, including meningiomas. Although valued for its low invasiveness and precision, it still carries a risk of complications. Communicating hydrocephalus is a serious, albeit rarely reported, complication of SRS.

Slit-ventricle syndrome masking shunt disconnection in adulthood.

A male in his 20s was referred to the neurosurgical service with headaches, vomiting and personality changes. He had a previous history of bilateral ventriculoperitoneal (VP) shunts and bitemporal decompressive surgery for neonatal intraventricular haemorrhage. There were appearances of slit-ventricles on his CT head scan typically associated with adequate cerebrospinal fluid drainage and normal intracranial pressure (ICP), which ordinarily will have limited further investigation.

Surgical Approaches to the Orbit: A Neurosurgical Perspective.

Orbital pathologies can be complex to manage surgically. In this article, we describe some of the most common and relevant approaches to orbital tumours. For each approach we describe the appropriate indications, surgical technique, potential complications, and illustrate a case example.

Rheumatoid Meningitis.

Background: Rheumatoid meningitis is a rare manifestation of autoimmune rheumatoid arthritis.

Case Description: A 70-year-old man with rheumatoid arthritis had presented with speech difficulties and limb weakness. Magnetic resonance imaging of his brain demonstrated diffuse meningeal enhancement.

Preoperative screening for coagulopathy in elective neurosurgical patients in Wellington Regional Hospital and survey of practice across Australia and New Zealand.

It is common practice to perform pre-operative coagulation screening in elective neurosurgery patients, including international normalised ratio (INR) and activated partial thromboplastin time (aPTT). We present a retrospective analysis of 1143 elective neurosurgical patients at Wellington Regional Hospital (WRH) in New Zealand between 2013 and 2017 on whom coagulation screening including INR and aPTT was performed prior to surgery. 21 patients (1.
