    Mediastinal pseudocysts can be challenging to locate accurately. Endoscopic retrograde cholangiopancreatography is recommended for precise preoperative evaluation of these pancreatic pseudocysts.

    Area of Science:

    • Gastroenterology
    • Surgical Oncology
    • Diagnostic Imaging

    Background:

    • Mediastinal pseudocysts often extend into the upper abdomen, complicating surgical decompression strategies.
    • Previous surgical cases predominantly involved pseudocysts with both thoracic and abdominal components.

    Observation:

    • A patient presented with a mediastinal pseudocyst suspected to straddle the diaphragm based on ultrasound and CT scans.
    • Surgical exploration revealed no abdominal component, despite preoperative imaging suggesting otherwise.

    Findings:

    • The mediastinal pseudocyst was successfully drained via a Roux-en-Y jejunal loop through the diaphragm.
    • Preoperative imaging modalities (ultrasound, CT) had limitations in precisely defining the pseudocyst's diaphragmatic relationship and abdominal extent.

    Implications:

    • Accurate preoperative assessment of mediastinal pseudocysts is crucial for effective surgical planning.
    • Endoscopic retrograde cholangiopancreatography (ERCP) is strongly recommended to delineate pseudocyst anatomy and guide surgical decompression.
    • This case highlights the potential for imaging to underestimate or misrepresent the extent of mediastinal pseudocysts.
