Case report. Aortic aneurysm presenting as psoas enlargement

S D Vibhakar, H Lee, M Petruschak

    Journal of Computer Assisted Tomography
    |December 1, 1981
    PubMed
    Summary

    Abdominal aortic aneurysms can enlarge the psoas muscle through bleeding. Needle biopsy can breach compartmentalization, connecting the retrofascial and extraperitoneal spaces.

    Area of Science:

    • Vascular Surgery
    • Anatomy

    Background:

    • Abdominal aortic aneurysms (AAAs) are a significant vascular condition.
    • Understanding AAA complications and anatomical involvements is crucial for surgical and diagnostic procedures.

    Observation:

    • A case of AAA presented with erosion and bleeding into the psoas muscle.
    • This bleeding caused significant enlargement of the psoas muscle structure.
    • The bleeding remained confined within the psoas muscle initially.

    Findings:

    • Needle biopsy of the enlarged psoas muscle created a communication with the extraperitoneal space.
    • This event confirmed the compartmentalization between retrofascial and extraperitoneal spaces.

    Implications:

    • Highlights the importance of anatomical planes in AAA complications.

  • Suggests potential risks associated with invasive procedures in cases of AAA with psoas involvement.
  • Reinforces the understanding of compartmentalization in maintaining containment of pathological processes.
