[Fascioliasis and brucellosis in same patient]

Brucellosis is a zoonotic infectious disease that can affect many organs and systems and leads to very different clinical circumstances. Brucellosis is rare in association with various infectious agents. Fascioliasis is a zoonotic disease caused by Fasciola hepatica, popularly referred to as a large leaf-shaped liver fluke. This case is a 39-year-old male patient, and his complaints began a week ago, which were chills, fever, abdominal pain, nausea, vomiting, weakness, sweating, and widespread pain. The patient was considered brucellosis in the preliminary diagnosis. Rose Bengal test and Wright test (1/640) were detected as positive. Due to patients having elevated liver enzymes, abdominal ultrasound was taken. A liver lesion was seen with abdominal ultrasound. So, abdominal computed tomography (CT) was taken. The CT result report came in the form that at the left lobe of the liver segment 2, largely necrosis that showed no contrast enhancement, approximately 61x63 mm in size (compatible with fascioliasis) is viewed. The patient's IHA test results, required for fascioliasis, were detected as 1/320 positive. Especially for zoonotic diseases in areas with high endemicity, it should be considered that more than one infectious agent can be present together in high-risk patients.
