The authors report a patient who presented with unexplained confusion. She was 15 weeks pregnant and had been having recurrent vomiting for several weeks. This was felt to possibly represent hyperemesis gravidarum, but she had several other possible contributing factors. Her serum sodium was 146 mmol/L, and her potassium was 2.6 mmol/L. She was alert but had disorientation, visual hallucinations, memory impairment, and confabulation despite being a college graduate with no history of illicit drug use or excessive alcohol consumption. Her initial magnetic resonance imaging (MRI) brain scan was interpreted as being normal. However, her follow‐up MRI brain scan revealed typical findings of central pontine myelinolysis, which correlated with hyperreflexia and positive Babinski reflexes. This patient illustrates the constellation of signs and symptoms that can be seen with a demyelinating lesion of the pons. In addition, our case illustrates how this MRI scan finding can be quite nonspecific but may help to explain the clinical findings.
