case_images: Images of acute subdural hematoma. (A-C) CT scan images showing an acute epidural hematoma in the right frontal lobe with retraction of the lateral ventricle anterior horn and herniation of the falx cerebri. (D,E) post-contrast MRI images showing neither vascular malformation nor brain tumor. (F-I) cerebral angiography showing neither vascular malformation nor aneurysm [(F,G) arterial phase; (H,I) venous phase]. (J-L) CT scan images obtained 7 days postoperatively showing successful removal of the hematoma. (M) macroscopic image of the removed hematoma. (N) microscopic image of the hematoma with Elastica van Gieson staining, demonstrating common pathological features of organized hematoma without vascular malformation or aneurysm. Scale bar, 500 mum.

case_images: Brain computed tomography (CT) revealed a large epidural hematoma in the right frontal lobe with midline shift (Figures 1A-C). In addition, radiological assessments using magnetic resonance imaging (MRI) and cerebral angiography detected no vascular malformation, aneurysm, or brain tumor (Figures 1D-I). Therefore, we performed direct evacuation and successfully removed a 12 g organized hematoma (Figures 1J-M). Histological analysis disclosed common findings of organized hematoma, but no evidence of vascular disruption, vascular malformation, or malignancy (Figure 1N).
