Computed tomography image of the present case.
. 
A, B: Image on the day of surgery; C, D: Image on the day after surgery. Arrows 1 and 2 show subdural hematoma in the right supratentorial and bilateral infratentorial regions. Arrow 3 shows the hematoma at the rostral surface of the tentorium.
. 
Arrows 4, 5, and 6 show a decrease in the subdural hematoma in the right supratentorial region, and the subdural hematoma in the infratentorial region has not increased. Arrow 7 shows that a hematoma at the rostral surface of the tentorial region has not increased.

Computed tomography (CT) showed a right supratentorial CSDH and bilateral infratentorial CSDH (Fig. 1A, B). CT and magnetic resonance imaging (MRI) showed a reduction of the right supratentorial CSDH, no change in the infratentorial CSDH, and no upper herniation (Fig. 1C, D, Fig. 2A, B).
Magnetic resonance image of the present case.

A, B: Image on the day after surgery; C, D: Image 1 week after surgery; E, F: Image 1 month after surgery.
. 
Arrows 1 and 2 show that the hematoma in the supratentorial and infratentorial regions has not increased. Arrows 3 and 4 show that a subdural hematoma in the supratentorial and infratentorial regions has decreased. Arrows 5 and 6 show that the subdural hematoma in the supratentorial and infratentorial regions is cured.

One week after surgery, an MRI image showed that the bilateral infratentorial subdural hematoma had decreased, and the supratentorial and bilateral infratentorial CSDH were cured 1 month after the surgery (Fig. 2C-F).
