case_images: Sagittal (T1-weighted (a), T2-weighted (b), STIR (c), and contrast-enhanced (d)) and axial (T1-weighted (e), T2-weighted (f), and contrast-enhanced (g)) magnetic resonance imaging revealed a large subdural hematoma extending from T2 to L3 and compressing the spinal cord from the ventral side at 7 days after onset.

case_images: Th7 was compressing and deforming the spinal cord centered on this region, and changes in intramedullary brightness of Th6 over Th8 were noted (Figure 1). There was no tumorous contrast enhancement in the mass region on contrast MRI, and no vascular malformation was observed on contrast-enhanced CT.
case_images: Axial noncontrast brain computed tomography showing a subarachnoid hemorrhage in the bilateral hemispheres at 7 days after onset.

case_images: Cranial SAH was detected in the bilateral parietal lobes and cerebral sulcus in the left occipital lobe on head CT (Figure 2).
case_images: Sagittal (T1-weighted (a), T2-weighted (b), STIR (c), and contrast-enhanced (d)) and axial (T1-weighted (e), T2-weighted (f), and contrast-enhanced (g)) magnetic resonance imaging showed resolution of the subdural hematoma and deformity of the spinal cord indicating adhesive arachnoiditis at 6 months after onset.

case_images: Th4-6 and displacement and deformity of the spinal cord were observed (Figure 3). These findings were considered to be due to adhesive arachnoiditis, but the course remained favorable thereafter.
