case_images: Horizontal eye movements were maintained [Figure 1].

case_images: A head computed tomography (CT) scan on admission showed a 10 x 13 x 13mm hemorrhage in the tegmentum of the midbrain [Figure 2].
case_images: Time course of magnetic resonance imaging ([a and b] on admission [c and d] after 11 days). (a and c) are slice of the level of pineal gland, and (b and c) are slice of the upper level of pineal gland. The hematoma remained in the right cover and the edematous change of the posterior commissure disappeared (arrow).

case_images: A head magnetic resonance (MR) imaging on the same day showed hemorrhage in the midbrain tegmentum and edema in the posterior commissure (PC) [Figures 3a and b]. On the 12th hospital day, all ocular symptoms disappeared except for downward gaze paralysis, and MR imaging during the same period showed that the hematoma was disappearing and the edematous changes near the PC disappeared [Figures 3c and d].
