- Background: Malignant rhabdoid tumors occasionally develop along cranial nerves, but clinical, histopathological, and
molecular features have not been examined in larger series.
Procedure: We retrospectively interrogated data from the European Rhabdoid Registry, EU-RHAB, to identify malignant rhabdoid
tumors affecting cranial nerves. We retrieved clinical information and reviewed magnetic resonance imaging (MRI) data.
Furthermore, histopathological review and molecular profiling were performed.
Results: Among 425 patients, we identified a total of 14 harboring malignant rhabdoid tumors with cranial nerve involvement.
Median age at diagnosis was 28 months (range: 0–13 years). Various cranial nerves were affected, the trigeminal nerve (n =
4) and the facial and/or vestibulocochlear nerve (n = 5) being most frequently involved. In most cases, the initial clinical and
neuroradiological suspicion was schwannoma. Neuroradiology review of magnetic resonance imaging studies confirmed aBackground: Malignant rhabdoid tumors occasionally develop along cranial nerves, but clinical, histopathological, and
