An isolated splenosis nodule was found incidentally in the hepatorenal recess. A history of splenic rupture should prompt a heat-damaged red blood cell scintiscan to avoid misdiagnosis and unnecessary biopsy.

Area of Science:

  • Medical imaging
  • Pathology
  • Surgical case reports

Background:

  • Splenosis, the autotransplantation of splenic tissue, can occur after splenic trauma or rupture.
  • It may present as a mass lesion, often mimicking other neoplastic or inflammatory conditions.
  • Accurate diagnosis is crucial for appropriate patient management.

Observation:

  • A case of incidentally discovered splenosis nodule in the hepatorenal peritoneal recess is presented.
  • Initial imaging suggested a non-renal retroperitoneal tumor.
  • The isolated location complicated the initial diagnostic assessment.

Findings:

  • The nodule's imaging features were initially misleading, pointing towards a retroperitoneal tumor.
  • Despite the unusual location, a history of splenic rupture was a key diagnostic clue.

  • A heat-damaged red blood cell scintiscan could have confirmed splenosis.

    • Implications:

    • This case highlights the importance of considering splenosis in the differential diagnosis of retroperitoneal masses, especially with a history of splenic injury.
    • Prompt recognition can prevent misdiagnosis and avoid invasive procedures like percutaneous biopsy.
    • Utilizing specific diagnostic modalities like scintigraphy can improve diagnostic accuracy for ectopic splenic tissue.
