[Supernumerary spleen simulating a renal tumor. Case report]. / Bazo supernumerario simulando un tumor renal: a propósito de un caso.

OBJECTIVE: Report one case of ectopic spleen simulating a renal tumor. We performed a review of etiopathogenesis, diagnosis and treatment. METHODS: We present the case of a 54-year-old splenectomized female patient with the incidental diagnosis on ultrasound of a left kidney upper pole mass simulating a renal tumor. RESULTS: After the performance of CT scan, and with the suspicion of renal neoplasia, the patient underwent tumorectomy with the pathologic diagnosis of the specimen compatible with supernumerary spleen. CONCLUSIONS: We emphasize the importance of including pseudo masses of splenic origin in the differential diagnosis of left renal, adrenal and retroperitoneal tumors. We emphasize the importance of CT scan as the imaging test of choice, and gammagraphy as a complementary test. We point out conservative attitude as the most suitable in cases of asymptomatic pseudomass of splenic origin.

Bazo supernumerario simulando un tumor renal: a propósito de un caso / Supernumerary spleen simulating a renal tumor. Case report

Objetivo: Presentar un caso de bazo ectópico simulando un tumor renal. Hacemos una revisión de la etiopatogenia, diagnóstico y del tratamiento. Método: Presentamos a una paciente de 54 años esplenectomizada que se le detecta incidentalmente mediante una ecografía una masa en polo superior del riñón izquierdo simulando un tumor renal. Resultados: Tras la realización de un TAC, y bajo la sospecha de neoplasia renal, se le practicó tumorectomía de la lesión observándose en el diagnóstico histológico posterior pieza compatible con bazo supernumerario. Conclusiones: Resaltamos la importancia de incluir las pseudomasas de origen esplénico dentro del diagnóstico diferencial de los tumores renales, suprarrenales y retroperitoneales izquierdos. Destacamos la importancia del TAC como técnica de elección y de la gammagrafía como estudio complementario. Apuntamos la actitud conservadora como la más idónea en los casos de pseudomasa de origen esplénico asintomática tumor (AU)
