Intrathoracic Herniated and Infected Pancreatic Pseudocyst

Key Points

To report a case of an infected pancreatic pseudocyst that extended into the thoracic cavity due to hiatal hernia.
Patient evaluation with laboratory tests and medical history
Imaging using 18 F-FDG-PET/CT
Endosonography and transgastric drainage
Antibiotic therapy
Laboratory tests showed elevated C-reactive protein levels
Endosonography removed 200 mL of pus
Klebsiella pneumoniae was identified as the infecting organism
Follow-up ultrasound indicated significant cyst regression
Patient discharged in satisfactory condition with reduced inflammation

Abstract

A 40-year-old man was admitted with acute diarrhoea, 3 kg weight loss, and mild fever (up to 38 °C). His medical history included acute necrotising pancreatitis and an axial hiatal hernia. Laboratory tests showed elevated inflammation parameters (C-reactive protein of 188 mg/L). A 18 F-FDG-PET/CT scan revealed infected abdominal pancreatic pseudocysts extending to the thoracic region due to the hiatal hernia. Endosonography and transgastric drainage removed 200 mL of pus. Klebsiella pneumoniae was identified, and antibiotic therapy with ampicillin and sulbactam was started. A follow-up ultrasound showed significant cyst regression. The patient was discharged in a satisfactory condition with reduced inflammation.
