Eikenella corrodens perirenal abscess resulting from a pancreatic fistula in a patient with chronic pancreatitis. Case report and literature review.

We present a case of a right perirenal Eikenella corrodens abscess in a patient with chronic pancreatitis and poor dental hygiene. Endoscopic Retrograde CholangioPancreaticography (ERCP) revealed a pancreatic fistula draining to the right perirenal loge. The patient was treated with broad-spectrum antibiotics, percutaneous drainage and endoscopic stenting of the duct of Wirsung, stopping the supply of the fistula. A full recovery in our patient was observed. Considering the uncommon location of the abscess, a review of the different aetiologies of perirenal abscesses and their distrubution patterns, and the endoscopic treatment of symptomatic pancreatic fistulas seemed worthwhile. © Acta Gastro-Enterologica Belgica.
