Clinical question: Intracranial hemorrhage? Signs and symptoms: Headaches. Non-enhanced MRI of brain:Extensive postoperative changes of large bifrontal craniotomy. Significant widening of the epidural space containing serosanguineous fluid and air. This is a postoperative findings. Epidural collection causes mass effect and posterior displacement of frontal lobes. Residual air within the subarachnoid space from patient's surgery. No evidence of parenchymal hemorrhage. Interval reduction in the low density cyst in the basal cistern. On the current exam the cyst measures approximately 19 mm in AP and 27-mm in transverse diameter. This is a smaller than prior examination which measured 25 mm x 36-mm. no evidence of hemorrhage within the cyst.
1.Reduction in the size of cyst within the basal cistern consistent with patient's past history of craniopharyngioma.2.Extensive postoperative changes all bifrontal craniotomy as detailed above.3.No evidence of acute hemorrhage within the brain parenchymal or cyst within the basal cistern.
