Clinical question: Headaches. Signs and symptoms: Postoperative hemorrhage? Nonenhanced CT of brain:Expected postoperative changes of right-sided suboccipital craniotomy. Residual air within the subarachnoid space in the posterior fossa, soft tissues of the scalp.Four ventricle remains within normal size and in the midline. No hemorrhage within the posterior fossa. Small foci of increased density in the right cerebellopontine angle is believed to be a post operative replaced center thick material for treatment of trigeminal neuralgia (microvascular decompression).Images through supratentorial space demonstrate mild bifurcation of lateral ventricles which appears similar to prior MRI examination from 6 -- 1 -- 2010
Expected postoperative changes of right suboccipital craniotomy as detailed.
