Pancreatic pseudocyst mimicking a left kidney abscess: a case report.

BACKGROUND

Pancreatic pseudocyst are fluid filled sacs that develop as a result of dissection of pancreatic enzyme tissue. While most commonly found near the pancreas, they can also rarely occur in other areas such as the perirenal region.

CASE PRESENTATION: This study reports a new case of an infected perirenal pancreatic pseudocyst mimicking a left kidney abscess in a 46-year-old North African patient with history of recurrent acute pancreatitis, who presented with left lumbar region pain and fever. Computed tomography revealed a left perirenal collection that turned out to be an infected pancreatic pseudocyst, The diagnostic was first suspected based on the medical history of the patient and confirmed by biochemical examination detecting a high level of pancreatic enzymes in the computed tomography-guided percutaneous drainage fluid. The patient evolved well after early resuscitation, rapid and effective antibiotic therapy, and computed tomography-guided percutaneous drainage of renal collection.

CONCLUSION

Pancreatic pseudocyst is an uncommon disorder, which may present at a complicated stage and that must be considered in patients with a history of pancreatitis.
