Status of intracranial injury. Seizure. There is a small amount of scattered T1 hyperintense subdural hemorrhage along the posterior falx cerebri and cerebelli that measures up to 3 mm in thickness. There is no significant associated mass effect or midline shift. There is minimal prominence of the subarachnoid CSF spaces in the bilateral anterior frontal and temporal regions, which likely represent hygromas. The brain parenchyma appears unremarkable without evidence of acute infarction or contusion. The ventricles are unchanged in size and configuration. There is minimal deformity of the occipital bone. The orbits and scalp soft tissues appear to be unremarkable. There is a subcentimeter T1 hypointense and T2 hyperintense lesion in the midline tongue base region.
1. Mild subacute subdural hemorrhage along the posterior falx cerebri and cerebelli without associated significant mass effect or cerebral contusion. 2. A subcentimeter T1 hypointense and T2 hyperintense lesion in the midline tongue base region is incompletely characterized, but may represent a thyroglossal duct cyst or vallecular retention cyst. An ultrasound may be useful for further evaluation.
