Une atteinte tuberculeuse rénale révélatrice d’un mal de Pott

Abstract

Tuberculosisis is a serious desease, causing high morbidity and mortality. It includes frequent extra-pulmonary forms, polymorphic in their clinico-radiological presentation, resultsing in a delayed diagnosis. We report the case of a rare association of renal tuberculosis and Pott's disease. It is the case of a 19-year-old patient. He has two brothers on chronic hemodialysis. He is hospitalized for exploration of a lumbar mass and a cachectic state. Radiological imaging (MRI, scanner) suggests osteosarcoma. The renal biopsy, performed for the nephrotic syndrome, reveals the presence of a granulomatous interstitial infiltration, which suggests a tuberculosis. The anatomo-pathological study, of the excisional piece of the lumbar mass, confirms the diagnosis of tuberculous spondylodiscitis. The clinico-biological evolution, with four antituberculous therapy is favorable, except for the persistence of the glomerular syndrome.
