[Bladder involvement in non-Hodgkin's lymphoma. Diagnosis and therapeutic response]

Presentation of one case of non-Hodgkin lymphoma (NHL) in a 76 year-old, female patient presenting with giant abdominal mass, secondary tumoral vesical infiltration and bilateral obstructive uropathy diagnosed by UIV, CAT and cystoscopy-biopsy. Transitory deobstruction with 'pig-tail' catheter allowed administration of therapy with multiple chemotherapy with excellent response. The radiological, endoscopic and histopathological findings, as well as the incidence of the uncommon vesical pathologies are reviewed.
