A 53-year-old man presented with acute onset of dizziness and titubation. He had a history of a slight head collision against the wall before admission. At hospitalization, he complained of drooping of his right upper eyelid, a hot sensation, and decreased sweating on the right side of his hemiface. Asymmetry of bilateral body temperature was also appeared. Neurologic examination revealed nystagmus. Miosis and ptosis were observed on the ipsilateral side. Sensation was impaired to temperature and light touch along the right side of his face and the left side of his body. Right-sided extremity ataxia was found. Hypohidrosis and fervescence was noted along the right side of his hemiface. Brain magnetic resonance imaging (MRI) revealed acute infarcts in the right lateral medulla due to vertebral artery dissection [Figure 1]. Infrared thermography images revealed a bilateral discrepancy in body surface temperature [Figure 2]. An increased body temperature was showed in the right side of his eye, mouth, neck, trunk, and limb, looking like a half-hot man. This symptom is thought to result from an infarction-induced disturbance of the descending sympathetic nerve tract, leading to an increased cutaneous blood flow and ipsilateral hypohidrosis.[1],[2]
Figure 1: High-resolution MRI and magnetic resonance angiography of the brain. Diffusion-weighted image (a) shows an acute infarction of the right lateral medulla. Magnetic resonance angiography (b) shows a long stenosis (white arrows) of the right vertebral artery. Three-dimensional space T1-weighted MRI of vertebral artery (c, d) reveals the high signals (arrowhead) of intramural hematoma indicating the diagnosis of dissection
