An initial computed tomography (CT) scan revealed a small intracerebral hematoma in the left ventrolateral thalamus (Fig. 1).
MRI revealed the typical signs of HOD. Isointensity in the enlarged right olivary nucleus is shown on the axial T1-weighted image (A), and hyperintensity is shown on the corresponding T2-weighted fluid-attenuated inversion recovery (FLAIR) image (B) (white arrow). The remote hemorrhage of the left dentate nucleus was better visible on susceptibility-weighted images (SWI) (D) than on the T2-weighted FLAIR image (C) (white arrow).

On the third day, the patient developed a slight involuntary jerking movement of the diaphragm, and a detailed magnetic resonance imaging (MRI) scan revealed the typical signs of HOD with isointensity in the enlarged right olivary nucleus on T1-weighted images and hyperintensity on the corresponding T2-weighted fluid-attenuated inversion recovery (FLAIR) images (Fig. 2A, B). T2-weighted FLAIR images (Fig. 2C, D). The patient's PM symptoms were controlled with oral clonazepam (2 mg, two times a day) and carbamazepine (0.2 g, three times a day).
