A 64-year-old female was admitted to the hospital because of a hepatic lesion incidentally diagnosed during acute cholangitis. Abdominal computed tomography (CT) and magnetic resonance imaging (MRI) showed a well delimited 70 mm mass, with a predominant cystic component and hyperenhancement of papillary internal branching, consistent with a hydatid cyst. However, malignancy could not be excluded. The patient rapidly developed an acute abdomen syndrome, thus precluding a liver biopsy. A new urgent CT was performed to rule out a complication of the cystic lesion. A left hepatectomy was performed and the anatomopathological study confirmed the diagnosis of IPNB with a focus of cholangiocarcinoma therein. During follow up, the patient developed peritoneal carcinomatosis, received palliative chemotherapy and finally died.enBile Duct NeoplasmsBile DuctsBile Ducts, IntrahepaticCholangiocarcinomaFemaleHepatectomyHumansMiddle Agedresearch article34425680open access10.17235/reed.2021.8193/2021https://online.reed.es/DOI/PDF/ArticuloDOI_8193_Temp.pdf
