Summary
Retrospective review of 1517 lumbar CT examinations revealed extraspinal pathology in 22 (1.45%). Retroperitoneal tumors and lymphadenopathy as well as vascular, urinary tract and gynecologic abnormalities were identified. This study demonstrates the need to carefully evaluate the visualized portions of the abdomen and pelvis on all lumbar spine CT examinations even when the patient's symptomatology is suggestive of spinal abnormalities.
