A rare, benign retroperitoneal schwannoma was incidentally discovered. Imaging suggested its nature, and angiography revealed portal vein compression, highlighting potential thrombosis risks.

Area of Science:

  • Oncology
  • Radiology
  • Gastroenterology

Background:

  • Schwannomas are rare, typically benign tumors originating from nerve sheath cells.
  • Retroperitoneal schwannomas are uncommon, often presenting incidentally due to their location.
  • Benign soft tissue tumors can affect various organs, including visceral structures.

Observation:

  • An incidentally discovered retroperitoneal mass was evaluated.
  • Ultrasound (US) and computed tomography (CT) imaging were utilized for initial assessment.
  • Angiography was performed to assess vascular involvement and potential complications.

Findings:

  • US and CT imaging suggested a benign neoplastic process.
  • Angiography demonstrated significant mass effect on the portal vein.

  • The findings indicated a risk of impending portal vein thrombosis.

    • Implications:

    • This case highlights the importance of cross-sectional imaging in diagnosing retroperitoneal masses.
    • Early detection of vascular compromise is crucial for preventing serious complications like portal thrombosis.
    • Surgical confirmation remains the gold standard for definitive diagnosis of retroperitoneal schwannomas.
