Vestibular schwannoma arising in the context of neurofibromatosis type 2 presents a distinct clinical picture that demands a tailored, situation-dependent management approach — one that differs meaningfully from sporadic cases.

Clinical Scenario

Patients with neurofibromatosis type 2 (NF2) characteristically develop bilateral vestibular schwannomas, or a unilateral vestibular schwannoma together with additional intracranial and/or spinal tumors. This tumor multiplicity, combined with the inherited nature of NF2, directly shapes the priorities and limits of any intervention.

Management Approach

Management is highly individualized to the clinical situation: it spans active surveillance with closer follow-up intervals at one end, through surgical options — including approaches specifically designed to preserve cranial nerve function — and stereotactic radiotherapy techniques at the other. The precise criteria that determine which path applies, and in what sequence, are defined in the full structured protocol.

Patients with NF2 suffer from bilateral VS or unilateral VS and other intracranial and/or spinal tumors (see Table 1).
Generally, observation and follow-up should use shorter intervals compared with spontaneous VS, particularly in younger patients.
Bilateral VS may lead to intense brainstem compression, making surgical decompression mandatory.
If incomplete resection is performed to preserve seventh and/or eighth cranial nerve function, residual tumors may be treated by SRS; in small tumors, observation may be appropriate.
