Abstract
Introduction
Longitudinally extensive transverse myelitis (LETM) is inflammation of the spinal cord that spans three or more spinal segments. LETM is a rare occurrence on its own and has seldom been reported with tuberculous meningitis (TBM), the rarest and deadliest of tuberculous manifestations. TBM is usually seen in children, the immunocompromised, or those with a previous history of tuberculosis infection.
Case presentation
A 24-year-old healthy male with no co-morbidities or history of tuberculosis presented with fever and headache for the past 3 months. The patient’s Kernig’s and Brudzinski’s signs were both negative, with bilateral abnormal plantar reflexes. The neurological level of injury was T8 and the patient was classified as AIS grade A. His CSF analysis showed a lymphocytic picture. However, both GeneXpert and Ziehl–Neelsen staining came back negative for Mycobacterium tuberculosis. MRI scans of the brain and thoracic spine revealed enhancing nodules and ring lesions in the brain and spinal cord, along with the rare complication of LETM, extending from T2 to T9.
Discussion
Although Mycobacterium tuberculosis was never isolated, the patient started recovering as soon as antituberculous therapy was initiated. Hence, more emphasis needs to be placed on radiological imaging in the management of rare medical emergencies like tuberculous meningitis, especially in areas where tuberculosis is rampant and endemic, rather than waiting for a positive culture. This case report also demonstrates the growing evidence that transverse myelitis and/or LETM is associated with TBM.
