MR imaging study in intradural extramedullary tuberculoma. Case report andliterature review

Intradural extramedullary tuberculoma without any bony involvement is excep tional. Nineteen cases were found in the literature. We report the case of 5-year-old boy who presented acute paraplegia 8 months after a tuberculous meningitis under antituberculous treatment. Dorsal gadolinium enhanced MRI revealed an intradural extramedullary bunch-shaped enhancing mass at T5-T6 level. The tuberculous nature was confirmed by histology after surgical rem oval of the lesion followed by a good recovery. To our knowledge, this is t he first intradural extramedullary tuberculoma detected by MRI. We underlin e the role of MRI in the diagnosis of this particular localisation of tuber culosis.
