[A rare case of hepatosplenic cat scratch disease].

ABSTRACT

A female patient in her 60s, treated with oral corticosteroids for scleroderma diagnosed 11 years ago, visited our hospital complaining of a persistent fever and liver dysfunction. She was treated with antibiotics, but her fever continued. Abdominal ultrasonography revealed multiple hypoechoic splenic masses. Splenic masses revealed multiple masses with no contrast effect in arterial and portal phases and nuclear in equilibrium phase by contrast computed tomography study, as well as hyperintensity masses with low signal areas in magnetic resonance imaging T2-weighted images. Liver tissue was obtained by percutaneous liver biopsy, and histological findings showed epithelioid cell granulomas without tumor cells. Further interview and physical examination revealed scratch scars from domestic cats and left axillary lymph node swelling. Hence, a cat scratch disease was suspected. She was diagnosed with cat scratch disease by serum indirect immunofluorescence. Her fever was resolved with minocycline administration. Therefore, persistent fever with splenic masses should be suspected of hepatosplenic cat scratch disease.
