Tear-drop shaped bladder

General Considerations
  • AKA tear-drop shaped bladder
  • Elongated appearance of the urinary bladder due to extrinsic compression by substance or disease described below
  • CT is most helpful in identifying the cause of the compression


  • Pelvic lipomatosis
  • Fluid in the pelvis, including blood
  • Bilateral pelvic lymphadenopathy
  • Bilateral iliac artery aneurysms
  • Hypertrophy of the psoas muscles

Imaging Findings

  • Narrow and elongated urinary bladder cause by symmetrical extrinsic compression
