case_images: (a)-(c) show the soft tissue windows of the emergency axial head CT without IV contrast of the patient on admission, showing a huge fusiform high-density shadow in the left frontotemporal parietal region, which is very similar to the common CT findings of acute epidural hematoma. (d) shows the soft tissue window of the axial head CT without IV contrast on the first postoperative day, showing that the organized subdural hematoma was almost cleared and the compression of the brain tissue was relieved.

case_images: When the outer membrane was cut open, a large amount of reddish-brown silt-like materials were found in the capsule cavity (Figure 2).
case_images: Postoperative pathology showed cystic tissue, fibrous collagen tissue with lymphocyte infiltration, and blood clots in the cyst. Picture was taken at 200 magnification.
