Retroperitoneal fibrosis (RPF) located unilateral perirenal without aorta involvement is very rare. We report a case of unilateral perirenal fibrosis which was misdiagnosed as malignancy even after biopsy. RPF should be in mind in dealing with perirenal mass.

EMPHASIS in the literature of retroperitoneal fibrosis is rightly directed towards the urinary tract as this is where its most serious effects are produced (Raper, 1956; Talbot & Mahoney, 1957). Gastro-intestinal symptoms may characterize the early stage of the illness and a gastro-intestinal tract origin cannot be excluded (Ormond, 1965).

BACKGROUND Retroperitoneal lymph node dissection has been advocated for the management of post-chemotherapy (PC-RPLND) residual masses of non-seminomatous germ cell tumors of the testis (NSGCT). There remains some debate as to the clinical benefit and associated morbidity. Our objective was to report our experience with PC-RPLND in NSGCT. METHODS We have reviewed the clinical, pathologic and ...

Two patients who had acute pancreatitis subsequently developed characteristic appearance on urography of smooth extrinsic narrowing and medial deviation of the right ureter suggestive of retroperitoneal fibrosis (RPF) resulting in ureteric obstruction. Both these patients had clinical, biochemical and sonographic evidence of acute pancreatitis. CT scan of the abdomen performed on the second pat...

CONTEXT Chronic alcoholic pancreatitis is a debilitating disease that is often complicated by pseudotumoral changes of the pancreas, retroperitoneal fibrosis, and pancreatic cancer. Actinomycosis is an uncommon intra-abdominal infection and its association with chronic pancreatitis has been rarely reported. CASE REPORT We present a case of a patient with progressive long standing chronic panc...
