A retroperitoneal accessory spleen, a rare lower abdominal mass, was identified. Its unique vascular supply originated independently from retroperitoneal vessels.

Area of Science:

  • Abdominal Imaging
  • Surgical Pathology
  • Vascular Anatomy

Background:

  • Accessory spleens are congenital anomalies, typically located in the splenic hilum or along the greater omentum.
  • Retroperitoneal location of an accessory spleen is exceptionally rare, posing diagnostic challenges.

Observation:

  • A patient presented with a palpable lower abdominal mass.
  • Imaging revealed a distinct retroperitoneal mass.
  • Surgical exploration and histopathological examination confirmed the mass as an accessory spleen.

Findings:

  • The accessory spleen was situated in the retroperitoneum.
  • Its vascular supply arose independently from retroperitoneal vessels, distinct from splenic, testicular, and spermatic vasculature.

Implications:

  • This case highlights the importance of considering rare anatomical variations in the differential diagnosis of abdominal masses.
  • Understanding the independent vascular supply is crucial for surgical planning and preventing complications.
  • Adds to the literature on the embryological development and anatomical variations of the spleen.
