Unilateral "vanishing psoas": an anatomic variant

Summary

Psoas muscle asymmetry, a common finding on abdominal CT scans, is typically a benign anatomical variant. This condition, where the lower psoas muscles are smaller, does not cause symptoms or indicate underlying disease.

Area of Science:

  • Radiology
  • Anatomy
  • Medical Imaging

Background:

  • Psoas muscle asymmetry can be identified during abdominal computed tomography (CT) examinations.
  • This asymmetry may involve a significant size reduction in the lower portion of the muscle.
  • The cause of this asymmetry is often unclear, with no associated neurological or other diseases identified.

Purpose of the Study:

  • To describe the characteristics of psoas muscle asymmetry observed in patients undergoing abdominal CT.
  • To determine if psoas muscle asymmetry is associated with any pathological conditions or symptoms.
  • To establish psoas muscle asymmetry as a potentially benign anatomical variant.

Main Methods:

  • Retrospective review of abdominal computed tomography (CT) examinations.
  • Identification of patients exhibiting obvious asymmetry of the psoas muscles.
  • Clinical data review to assess for neurological or other explanatory diseases and patient symptoms.

Main Results:

  • Five patients with obvious psoas muscle asymmetry were identified.
  • In all cases, the upper psoas muscle was normal, while the lower portion was significantly reduced in size.
  • No patient had an identifiable underlying disease or experienced symptoms related to the psoas asymmetry.

Conclusions:

  • Psoas muscle asymmetry is an apparent benign anatomical variant.
  • Recognition of this variant on CT is important to differentiate it from pathological conditions.
  • This finding does not require further investigation or intervention in the absence of other pathology.
