Figure 2.

A 30-year-old woman with a gunshot wound to the back of the head. (a) computed tomography (CT)-scout image anterior view and (b) lateral view. Arrows demonstrate the left suboccipital target site with an intact bullet (c) Admission CT, axial views in bone windows, showing the bullet which was lodged behind the petrous bone (d) Soft tissue windows, demonstrating the focal posterior fossa hemorrhage near the cerebellopontine angle, but leaving an intact brain stem. A second significant hemorrhage/collection under the occipital bone is visible possibly originating from the sinus. Note the dilated temporal horns bilaterally indicative of obstructive hydrocephalus prior to external ventricular drain insertion. (e) Immediate postoperative scan after a wide bilateral suboccipital midline craniectomy with expansile onlay duroplasty. (f) This scan shows a postoperative scan of the same slice location in soft tissue windows after decompression as indicated by the arrows
