Tuberculosis of the spine. CT demonstration of paravertebral abscess

Two surgically proven cases of tuberculous psoas abscess are presented. The common findings on CT were low-density paraspinal masses and extension of the lesions which followed the typical distribution of iliopsoas muscle in both cases. The skeletal findings from the spine are also discussed. Our cases indicate the complementary use of plain radiography and CT in the investigation of tuberculous spondylitis.
