She was treated with intravenous fluids, thiamine and antiemetics. MRI brain showed hyperintensities in bilateral dorsomedial thalami, periaqueductal grey matter in T2-weighted and FLAIR images. A diagnosis of Wernicke encephalopathy was made and she was managed in intensive care unit and received injection thiamine as per the guidelines and her weakness and ataxia improved over 3 weeks and she was discharged at 17 weeks of pregnancy in good state of health.
