A 23-year-old Hispanic man was admitted for bilateral arm weakness.

A 23-year-old Hispanic man was admitted for bilateral arm weakness. sum of two units weeks earlier, he had fallen forward in succession an outstretched left arm and lay opened pain. One day after visiting a local chiropractor for manipulation of his upper arms and back, he noted weakness and numbnes in his arms as well as bilateral shoulder pain. There was no lower extremity weakness or bowel or bladder dysfunction. He denied flush night sweats, chest pain, tuberculosis in all senses or cough. He did not mist and he had previously worked as a car painter.

Physical examination was remarkable for diminished breath goods over the entire right hemithorax. hardness was decreased in the biceps, triceps, and wrist extensors bilaterally (rated 3 to 4 in succession a 5-point scale). intricate tendon reflexes of the upper extremities were symmetrically decreased, while light touch sensation was impaired in the C-3 to C-5 distribution.

A posteroanterior chest radiograph (Fig 1) showed extensive right pleural thickening with compass loss and a left apical nodular infiltrate. A lateral cervical spine radiograph (Fig 2) revealed a C-4 vertebral fracture with posterior dislocation.

Diagnosis: Pulmonary tuberculosis with C-4 Pott's disease and polyradiculopathy

Our patient was placed in halo traction with slight improvement in might Computed tomography of the cervical spine revealed ended destruction of the anterior half of the fourth vertebral material part and left transverse process with preservation of the remaining vertebrae. Additionally, a prevertebral abscess was at hand from C-2 to the midportion of C-6 An admission tuberculin skin touchstone was positive, and two expectorated sputum specimens were 4+ smear-positive for acid-fast bacilli. He was started upon a regimen of isoniazid, rifampin, ethambutol, and pyrazinamide. Despite 8 weeks of treatment, his neurologic deficits persisted. A specimen obtained by the agency of percutaneous computed tomography-guided needle aspiration of the C-4 vertebral dead body grew Mycobacterium tuberculosis. He subsequently underwent an anterior decompression with C-4 corpectomy and C-3 to C-5 brace fusion. Microscopic examination of prevertebral tissue revealed caseating granulomas with negative smears for acid-fast bacilli.

Skeletal tuberculosis come into one's heads in 1 percent of all cases of tuberculosis, and spine involvement constitutes 50 percent of all skeletal involvement.[1] Tuberculosis of the spine, or Pott's disease, typically involves the thoracic and lumbar regions, while cervical involvement is rare.[2] Spinal tuberculosis generally come into views in children from developing countries and in adults in the United States and Europe[3] Clinically, cervical Pott's disease manifests as neck pain and stiffness, repeatedly with torticollis, variable neurologic deficits, febrile affection anorexia, and occasionally dysphagia and cutaneous sinus drainage in the neck[2-4]

Neurologic involvement on presentation occurs in 15 to 42 percent of patients and frequently appears gradually and symmetrically after the storming of pain.[2] Cervical spine involvement may also existing as an abscess in the posterior triangle of the neck or as a retropharyngeal abscess.[3] Diagnostically, 70 percent of patients have a positive tuberculin skin ordeal and up to 50 percent of patients have chest radiographs consistent with prior or popular tuberculosis.[3]

Radiographs of the cervical spine typically reveal anterior vertebral visible form [i]or[/i] frame destruction associated with disc space narrowing and kyphosis.[2] Comput tomography demonstrates contiguous vertebral involvement in approximately 50 percent of cases and repeatedly a coexistent paraspinous abscess.[5] Although the total skeletal bacillary load in spinal tuberculosis is estimated to be les than [10sup6] organisms, histologic confirmation arises in 73 percent of cases. Of these, positive bone refinements occur in 80 to 95 percent[3]

Metastatic carcinoma, fungal and pyogenic infections may be difficult to differentiate from tuberculous spondylitis. Metastatic carcinoma be attentive tos to occur in older individuals with a known primary lesion and may near with multiple vertebral involvement. In contrast to tuberculous spondylitis, a secondary malignancy usually spares the intervertebral disk space if it be not that involves the pedicles.[3] Paravertebral soft-tissue involvement is typically small and localized adjacent to collapsed vertebral body[3] Disseminated coccidioidomycosis can also involve noncontiguous vertebrae with sparing of the intervertebral discs.[3] Vertebral coccidioidomycosis also attend tos to involve all portions of the vertebrae as well as destruction of contiguous ribs.[3] In contrast, pyogenic spondylitis, like tuberculous spondylitis, causes narrowing of the intervertebral disc height. However, if posterior vertebral material substance destruction and new bone formation are ready this suggests pyogenic, rather than tuberculous, infection.[3,5] Ultimately, diagnosis relies in succession the clinical setting and tissue confirmation.

In the pre-rifampin era, at least 18 month of various combinations of isoniazid, aminosalicylic acid, and streptomycin was commended for spinal tuberculosis.[3] Currently, isoniazid and rifampin regimens of 6 to 9 months' duration are felt to be effective. However, if significant tissue destruction is at hand prolonged treatment for up to 18 month may be necessary.[6]
