Increased intracranial pressure in NF2‑related schwannomatosis: an underestimated danger with serious consequences

Advances in the management of NF2-related schwannomatosis (NF2-SWN) have improved survival, but long-term complications such as increased intracranial pressure (IICP) remain insufficiently characterized. This study investigated the mechanisms, clinical presentation, and prognostic impact of IICP in NF2-SWN.

✦ Clinical Takeaway ✦

Audiologists and vestibular specialists managing patients with NF2-related schwannomatosis should be alert to signs of raised intracranial pressure and ensure prompt referral to neurology or neurosurgery, as this complication appears under-recognised and can cause serious long-term harm.

✦ Why It Matters ✦

Highlighting intracranial hypertension as an underestimated complication in NF2-related schwannomatosis may prompt earlier interdisciplinary surveillance protocols, potentially preventing irreversible neurological harm in a population already managed by audiologists.

✦ Key Points ✦

01NF2-related schwannomatosis is associated with bilateral vestibular schwannomas and progressive hearing loss.
02Raised intracranial pressure is identified as a long-term but under-recognised complication in this population.
03Delayed detection of intracranial hypertension can lead to serious consequences including vision loss and neurological decline.
04Published in the Journal of Neuro-Oncology (PMID 42168700).
05Findings support need for routine neurological surveillance alongside audiological monitoring in NF2 patients.
