Listeria monocytogenes peritonitis: an unusual presentation and review of the literature.

Listeria monotogenes bacteria-ascites developed in a 73-year-old man who had cholangiocarcinoma and liver metastasis. Spontaneous bacterial peritonitis (SBP) is a frequent complication in patients with chronic liver disease and ascites. L. peritonitis has been reported in only <30 cases world-wide. Our patient represents a unique case of L. peritonitis without peritoneal fluid analysis consistent with spontaneous bacteria peritonitis. However, the culture of the ascitic fluid provided the final diagnosis in this case.
