Infected pancreatic necrosis is a postpancreatitis complication that is mainly caused by Enterobacteriaceae and Enterococci. Here, we have reported a very rare case of Lactobacillus paracasei bacteraemia associated with infected pancreatic necrosis and retroperitoneal abscess. In addition to the diagnosis of diabetic ketoacidosis, blood test results revealed a high inflammatory status. CT of the abdomen revealed pancreatic walled-off necrosis. Blood culture and aspiration fluid culture revealed positivity for L. paracasei, leading to the diagnosis of infected pancreatic necrosis. The abscess had spread in the retroperitoneal space later. The patient recovered after receiving antibiotic treatment and endoscopic and percutaneous drainage. L. paracasei can cause invasive infection, including infected pancreatic necrosis and retroperitoneal abscess, which requires aggressive therapy.
