Micturitional disturbance in Wernicke's encephalopathy.
A 24-year-old pregnant woman started to have hyperemesis gravidarum 6 weeks before admission. Four weeks later she had vertigo, diplopia, staggering gait, mild dyspnea, dysphagia, and incontinence of urine. On admission she presented with ophthalmoplegia, ptosis, ataxia, decreased tendon reflex, and memory disturbance. Brain magnetic resonance imaging revealed abnormal intensities in medial thalamic-hypothalamic regions and the periaqueductal area, and she was diagnosed with Wernicke's encephalopathy. Urodynamic studies revealed decreased bladder volume and detrusor hyperreflexia. Six weeks after the administration of 100 mg/day of thiamine, urge incontinence gradually recovered, together with neurological signs. Lesions of the medial thalamic-hypothalamic area and the periaqueductal gray matter seemed to be mainly responsible for micturitional disturbance in our patient with Wernicke's encephalopathy.
