Acute fatty liver of pregnancy is a rare but highly fatal disease affecting women most frequently during the third trimester of pregnancy or in the postpartum period. It is considered a diagnosis of exclusion and requires a timely diagnosis to avoid maternal mortality. We present the case of a 33-year-old primigravida who required an emergency cesarean section due to fetal bradycardia. On postoperative day one, the patient was noted jaundiced, oliguric, and hypoglycemic. Laboratory tests revealed important hepatic dysfunction, coagulopathy, and renal failure. She was admitted to the Intensive Care Unit with the suspicion of acute fatty liver of pregnancy. Plasma exchange was started on postoperative day 5 with major clinical and laboratory improvement. A transjugular hepatic biopsy confirmed the diagnosis. The patient had satisfactory evolution and was discharged 15 days after delivery. Acute fatty liver of pregnancy is a highly morbid disease that needs a high index of suspicion to be diagnosed. Admission to an Intensive Care Unit to ensure maximum supportive care is mandatory in this disease.
