BACKGROUND Tuberculosis (TB) mostly attacks the lungs, and extrapulmonary TB involving thecentral nervous system is uncommon;among these cases, spinal intramedullaryTB is even more rare. The clinical manifestations of spinal intramedullary TB aresimilar to those of intramedullary spinal cord tumors. Therefore, it is necessary tomake a careful differential diagnosis of spinal intramedullary lesions to achievethe appropriate treatment and favorable prognosis. We report a rare case of ayoung male patient with paraplegia due to spinal intramedullary TB, which isuncommon and regrettable.CASE SUMMARY A 23-year-old male presented with fever accompanied by nausea and vomitinglasting for 2 mo and was then diagnosed with tubercular meningitis. After anti-TBtreatment, his symptoms were significantly improved. However, 2 mo after thediagnosis of tubercular meningitis, the patient felt numbness below the costal archlevel, which lasted for 1 wk, and he paid no attention to this symptom. Whatfollowed was paraplegia and urine/fecal incontinence. Magnetic resonanceimaging of the thoracic spine showed a ring-enhanced intramedullary cord lesionat T8-T9. Lesion exploration showed enlargement of the spinal cord at T8-T9, andthe lesion could be observed by incision. The lesion was adhered to the peripheraltissue and was grayish-white and tough with a poor blood supply and a diameterof approximately 0.8 cm. The lesion was resected completely. The results ofpathological examination by both hematoxylin-eosin staining and acid-fast bacillistaining confirmed TB, accompanied by acute and chronic suppurativeinflammation and granulation tissue formation. The patient was instructed tocontinue anti-TB treatment after the operation, but he did not follow the medicaladvice. Follow-up continued for ten years, the patient had persistent paraplegia,the numbness disappeared and urine/fecal sensation recovered.CONCLUSION Although TB is a kind of benign disease, some cases progress rapidly. Moreover,spinal intramedullary TB may seriously endanger quality of life and still needstimely diagnosis and proper treatment.
