Case presentation: We present the case of a 44-year-old male patient, currently incarcerated, who presented with a four-month history of progressive back pain. He subsequently developed paresthesia, decreased sensation and motor function beginning in the T4 dermatome, impaired bowel and bladder control, and paraparesis with hyperreflexia. An imaging study performed five months after the onset of symptoms revealed an extensive retropleural space-occupying lesion extending from T3 to T12. Due to the established chronic neurological deficit, two possible approaches were considered: percutaneous biopsy versus thoracotomy. A right posterolateral thoracotomy between the 5th and 6th ribs was chosen, with the participation of thoracic surgery and neurosurgery teams. Excision of approximately 250 grams of a yellowish, granular, Caseo-type mass was achieved, and a biopsy of the granuloma was taken. A chest tube was left in place and there were no post-operative complications. Results: The caseous material analysis showed: absence of acid-fast bacilli or bacterial morphology, presence of -3 leukocytes/field, no fungal elements were observed on KOH, and the culture was negative at 48 hours. The granulomatous tissue biopsy showed: chronic “caseating” (necrotizing) inflammation consistent with tuberculous etiology. The postoperative course was satisfactory with a decrease in pain within 24 hours. Pharmacological treatment was initiated with rifampicin, isoniazid, and ethambutol, with excellent results; absence of pain, although dystonia persisted in the lower extremities with paraparesis. Conclusions: It can be concluded that the diagnostic approach to vertebral tuberculosis in immunocompetent patients is complex, as it is a rare entity; however, a high clinical suspicion with appropriate selection of diagnostic methods can be useful.},
