Nonenhanced head. Examination demonstrates postoperative changes of a left anterior temporal and frontal craniotomy for drainage of subdural. Residual subdural and extensive post procedural air collection within the subdural space results seen mass effect on the adjacent left frontal, temporal lobes and rightward midline deviation of 9 mm. There is interval increased mass effect and deviation of midline likely secondary to excessive air entrapment under the craniotomy flap. No evidence of ventriculomegaly. Postprocedural air appears to extend through the anterior edge of craniotomy flap into the extracranial soft tissues of the scalp. Possibility of a ball valve mechanism should be considered. The largest measurement of remaining subdural hemorrhage and subdural air is approximately 21 mm. The small acute subdural is also noted along the anterior edge of right frontal lobe and extending into the interhemispheric fissure. Subdural also is noted to extend along the falx on the right posteriorly to the right parietal region. This collection is largest in the anterior frontal and measures maximum of 6.5 mm coronal reformatted series 80320 image 22. No evidence of parenchymal edema or hemorrhage. CSF cisterns remain widely patent and images through posterior fossa are unremarkable.
