Article Synopsis
- Very low pressure hydrocephalus (VLPH) is a rare condition often leading to poor outcomes and can be resistant to treatment, particularly with cerebrospinal fluid (CSF) drainage at low pressures.
- The study reviewed four cases of VLPH to identify factors that could help determine the best treatment approach and aimed to avoid unnecessary prolonged external ventricular drainage in patients who likely wouldn't improve.
- Findings suggest that improving Glasgow Coma Score (GCS) is linked to decreasing the frontal horn ratio and optimal CSF drainage, with good outcomes being dependent on brain viscoelasticity rather than mere fluid levels.
Object: Concerns about extreme peritumoral edema and its ensuing surgical and perioperative complications led the authors to use the bilateral fronto-orbito-nasal approach to remove midline anterior skull base meningiomas that were larger than 4 cm. The authors hypothesize that extreme vasogenic edema exemplified by finger-like hyperintensities extending into the bifrontal white matter and external capsule and/or the extreme capsule, coined the lion's mane sign (LMS), would help identify patients with a challenging postoperative course. They hypothesize that the LMS would better predict symptomatic postoperative cerebral edema than the edema index (EI).
