Serial CT brain imaging in follow-up, showing gradual enlargement of right tentorial SDH. (A) initial view of scanty right tentorial SDH, (B, C) status of SDH 16 and 26 hrs later, respectively, enlarging and propagating to right convexity, and (D) post-operative view.. Abbreviations: CT, computed tomography; SDH, subdural hematoma.

Computed tomography (CT) of the brain disclosed an acute SDH, scantily distributed along right tentorium (Figure 1A). Follow-up CT images of the brain showed noticeable enlargement of an acute SDH, compressing and elevating the occipito-temporal base (Figures 1B and 2A, B). He was stuporous, and the acute SDH had enlarged substantially (Figure 1C). Once the tentorial SDH was completely evacuated, brain compression improved (Figures 1D and 2C, D).
Pre- and post-operative CT images of the brain confirming evacuation of SDH and improvement of brain compression. (A, B) pre-, and (C, D) post-operative images (sagittal and coronal view, respectively).. Abbreviations: CT, computed tomography; SDH, subdural hematoma.

Illustration of the surgical approach depicting craniotomy and  -shaped dural incision. The craniotomy site was approximately 7.5 cmx7.5 cm square. The distance from the medial margin of the craniotomy to the midline was 1.5 cm, and the distance from the lower margin to the transverse sinus was 1 cm.

The craniotomy site was almost square and measured approximately 7.5 cmx7.5 cm; the distances between the medial margin of the craniotomy and the SSS and the lower margin of the craniotomy and the TS were approximately 1.5 cm and 1 cm, respectively (Figure 3).
