Near infrared spectroscopy as possible non-invasive monitor of slow vasogenic ICP waves.

We aimed to study synchronisation between ICP and near infrared spectroscopy (NIRS) variables induced by vasogenic waves of ICP during an infusion study in hydrocephalic patients and after TBI. Nineteen patients presenting with hydrocephalus underwent a diagnostic intraventricular constant-flow infusion test. The original concept of the methodology, presented in the current paper, was derived from this material.

Spontaneous cerebrospinal fluid rhinorrhoea as the presenting feature of an invasive macroprolactinoma.

A 29-year-old male university student, with no prior history of trauma, presented with a 1 year history of clear fluid leaking intermittently from his left nostril. His past medical history included bilateral gynaecomastia since age 12, and recent low libido. β2-transferrin analysis of the nasal fluid confirmed a diagnosis of cerebrospinal fluid (CSF) rhinorrhoea.
