Obstructive sleep apnea syndrome in a patient with medulloblastoma.

ABSTRACT

We present one adult patient with medulloblastoma who developed polysomnographically documented obstructive sleep apnea after posterior fossa surgery. The sleep apnea worsened in conjunction with clinical and imaging-confirmed neoplastic progression and clinically improved after craniospinal radiation therapy. Medulloblastoma or its surgical treatment has never before been implicated in a sleep-related breathing disorder. We discuss possible mechanisms for its occurrence and management implications.
