Biliary Peritonitis due to a Ruptured Amebic Liver Abscess Mimicking a Periampullary Tumor and Liver Metastases with the Elevation of CA 19-9 and CA 125: A Case Report.

INTRODUCTION

An amebic liver abscess is the most common presentation of extraintestinal amebiasis. This condition is the result of a parasite infection caused by Entamoeba histolytica.

MATERIALS AND

METHODS

We report a case of a 53-year-old male who presented with abdominal pain in the right upper quadrant, jaundice, and a 10-kg weight loss within a 1-month span.

RESULTS AND

CONCLUSION

A wide range of symptoms and findings in the imaging tests suggestive of neoplasia, elevated levels of CA 19-9 and CA 125, and the presentation of biliary peritonitis as a complication makes this case a challenge for its approach and management.
