Delayed Supratentorial Intracerebral Hemorrhage After Posterior Fossa Acoustic Neuroma Surgery.

A 72-year-old female patient was complaining from gradual loss of hearing in the left ear, left facial palsy with gait imbalance. Neuroimaging showed left cerebellopontine angle extra-axial mass and was diagnosed as acoustic neuroma. She was operated with left retromastoid suboccipital and gross total excision of the tumor was achieved. Early postoperative period was uneventful and brain computed tomographic (CT) scan in the postoperative day 1 showed gross total resection of the tumor without complications, and patient was discharged at the postoperative day 4. In the postoperative day 7, the patient showed decrease level of consciousness and brain CT scan showed a small hematoma in the anterior part of the left temporal lobe, which was evolved to large intraparanchymal hemorrhage with midline shift in postoperative day 9.
