Evolution of Subdural Collection through sequential computed tomography scans. The collection reaches its peak volume by day 31, then, a subdural catheter is placed by day 32. By day 35, cranioplasty is performed and then the collection steadily decreases until complete resolution by day 56

A head Computed Tomography (CT) was performed, showing a left frontotemporal subdural hematoma 11 mm width, collapsed quadrigeminal cistern and a 3 mm midline shift[Figure 1]. During the following days, several CT scans were performed, showing a growing liquid collection under the skin flap[Figure 1]. A new CT scan was obtained, showing a greater subdural hygroma, with a left to right midline shift of 13 mm[Figure 1]. On the assumption that the patient could present another episode of deterioration, a closed subdural drainage was kept in place for 5 days[Figure 1].
Surgical view: Brain parenchyma is depressed, and neomembranes are seeing in the operative field with thick vessels
