CTICasesTuberculous Paraspinal Mass
Imaging findings
Chest CT demonstrates a well-rounded soft tissue mass extending into two thoracic neural foramina and causing pressure erosion of the adjacent vertebral bodies, mimicking a neurogenic tumor. Biopsy of the mass showed chronic granulomatous tissue with acid-fast bacilli, confirming active tuberculosis. The patient also has an incidental congenital right aortic arch with an isolated left subclavian artery.
Key takeaways
Tuberculous spondylitis and paraspinal abscesses usually present with destructive bone changes, but can occasionally present as a well-defined, minimally destructive soft tissue mass mimicking a neurogenic tumor.
