A 17-year-old boy with hemifacial flushing and anhidrosis
Abstract
A 17-year-old boy presented with a long-standing history of episodic unilateral flushing and hyperhidrosis involving the left hemiface, scalp, and shoulder, first noted at age 2. Episodes were consistently triggered by heat, exercise, or emotional stress and were accompanied by contralateral (right-sided) anhidrosis/hypohidrosis, creating a striking midline asymmetry. He denied any neurologic symptoms, trauma, or previous surgeries. Neurologic examination was normal, and magnetic resonance imaging of the brain and cervicothoracic spine excluded structural or compressive lesions.
