Info

The patient is status post right frontal subdural drain placement with a subsequent decrease in size of the mixed density right holohemispheric subdural hematoma.

There is decreased leftward midline shift compared to the prior exam. There is essentially unchanged effacement of the right lateral ventricle, with a mild decrease in effacement of the third ventricle.

Case Discussion

This is a subdural drain, specifically a Subdural Evacuating Port SystemTM (SEPS; Medtronic, Minnesota, USA). After receiving the subdural drain, the patient continued to improve clinically. Repeat CTs revealed a progressive decrease of the subdural hematoma.
