Abstract

Hemorrhagic transformation of vestibular schwannoma following stereotactic radiation is a rare but serious complication. We report a case presenting with acute facial paralysis due to intratumoral hemorrhage 12 years after stereotactic radiosurgery. This case highlights hemorrhagic transformation as a potential cause of sudden neurological deterioration in previously irradiated vestibular schwannomas and underscores the importance of long-term MRI surveillance for early detection and timely intervention.
