Hyperemesis gravidarum-induced Wernicke’s encephalopathy

Wernicke’s encephalopathy is a potentially fatal but readily reversible medical emergency caused by thiamine deficiency. A 30-year-old, 14 weeks pregnant South Indian woman presented with confusion, diplopia, blurring of vision, gait ataxia, nystagmus and conjugate gaze palsy with a background of intractable hyperemesis gravidarum. With clinical suspicion and radiological confirmation, she was diagnosed to have Wernicke’s encephalopathy.
