Al examen: linfadenomegalia, taquicardia, soplo sistólico III/VI mitral y aórtico, Catalogado como fiebre de origen desconocido, Ecografía abdominal: hepato-esplenomegalia leve; ecocardiografía transesofágica: masa calcificada de 4,5 x 8 mm en válvula aortica y leve efusión pericárdica; tomografía abdominal: hepatoesplenomegalia leve, ganglios paraaórticos abdominales y una imagen captadora de contraste en hilio renal derecho de 15 x 25 mm, de bordes definidos. Leucocitosis neutrofílica, anemia moderada, ferritina > 2 000 ng/ ml., FR, ANA Y ANCA negativos. Ganglio cervical: reacción inflamatoria inespecífica; histopatología del tumor renal: carcinoma renal de células claras. A pesar de exéresis del tumor renal, la fiebre persistía; por exclusión, se diagnosticó enfermedad de Still del adulto (ESA) asociado a endocarditis trombótica no bacteriana (ETNB); recibió prednisona 1 mg/kg, con respuesta favorable. CONCLUSION.

Examination, lymphadenopathy; tachycardia, III/VI systolic murmur in mitral and aortic areas. It was considered as fever of unknown origin. Abdominal ultrasound: mild hepato-splenomegaly; transesophageal echocardiography: calcified mass of 4,5 x 8 mm in the aortic valve and mild pericardial effusion; abdominal tomography: mild hepato-splenomegaly, abdominal para-aortic lymph nodes and an image with contrast uptake at the level of the right renal hilum of 15 x 25 mm, with defined borders. Moderate leukocytosis with neutrophilia, moderate anemia, ferritin > 2000 ng/mL, negative for RF, ANA and ANCA. Cervical lymph node: unspecific inflammatory reaction; histopathology from the renal tumor: clear-cell renal carcinoma. Despite removal of the renal tumor, the fever persisted; by exclusion, was diagnosed as adult Still's disease (ASD) associated with non-bacterial thrombotic endocarditis (NBTE); treatment was initiated with prednisone at 1 mg/kg, obtaining positive result.
