A neck mass with brachial plexus injury: Pott's disease.

Tuberculous osteomyelitis of the spine is most commonly seen in lower thoracic and lumbar vertebrae. Cervical spine tuberculosis is a very rare condition, and it represents a very small part of all patients with Pott's disease. We present a case with thoraco-cervical Pott's disease, with left-sided neck mass and left arm and hand weakness and numbness. The patient had a paraspinal abscess under the sternocleidomastoid muscle that was compressing the brachial plexus.
