Intrahepatic Cholangiocarcinoma Masquerading as Acute Fatty Liver of Pregnancy: A Case Report and Review of the Literature

Abstract EN

Cholangiocarcinoma (CCA) is an uncommon cancer and accounts only for 3% of all gastrointestinal malignancies.

In this report, we present a case of an intrahepatic cholangiocarcinoma masquerading as acute fatty liver of pregnancy (AFLP).

A 38-year-old female who is 36-week pregnant presented with a 1-week history of headache, nausea, vomiting, and right upper abdominal pain, along with hepatomegaly.

Laboratory investigations were remarkable for mild leukocytosis, hyperbilirubinemia, proteinuria, and elevated transaminases and prothrombin time.

Ultrasound of the liver revealed hepatomegaly, fatty infiltration, and a right hepatic lobe mass.

Based on the overall picture, AFLP was suspected, and the patient underwent delivery by Cesarean section.

However, bilirubin and liver enzyme levels gradually increased after delivery.

MRI revealed a large dominant hepatic mass along with multiple satellite lesions in both lobes.

Biopsy revealed the presence of intrahepatic CCA.

CCA presenting during pregnancy is extremely rare with only 9 other cases reported in the literature.

Therefore, the signs and symptoms can be easily confused with other more common disorders that occur during pregnancy.
