Rarer still are extensive en plaque intradural extramedullary tuberculomas occurring concurrently with multiple intracranial tuberculomas as a paradoxical response to chemotherapy for tuberculosis (TB). The authors describe the case of a 21-year-old man who was treated for tuberculous meningitis. Three months after the episode of meningitis, while undergoing chemotherapy for TB, he developed features of thoracic myelopathy. Investigations revealed an extensive en plaque intradural extramedullary lesion spanning seven segments in the lower thoracic spine. Magnetic resonance imaging of the brain revealed multiple asymptomatic intracranial tuberculomas. Even after further treatment with antituberculous chemotherapy was initiated, the lesion failed to respond. The authors performed a laminectomy and excised the en plaque intradural extramedullary lesion. The patient\u2019s condition responded well to this treatment.<\/jats:p><jats:p>Although the appearance of intracranial tuberculoma as a paradoxical response to chemotherapy has been previously reported, no authors have reported on the development of an extensive en plaque intradural extramedullary tuberculoma in conjunction with asymptomatic multiple intracranial tuberculomas as a paradoxical response.<\/jats:p><jats:p>In cases in which patients present with compressive myelopathy following therapy for tuberculous meningitis, it is important to consider in the differential diagnosis that intradural extramedullary tuberculoma may be a paradoxical response to chemotherapy. The authors\u2019 experience and their review of the literature indicate that surgery has a definitive role to play in the management of spinal intradural extramedullary tuberculoma.<\/jats:p>","DOI":"10.3171\/spi.2007.6.2.169","type":"journal-article","created":{"date-parts":[[2008,1,24]],"date-time":"2008-01-24T13:15:32Z","timestamp":1201180532000},"page":"169-173","source":"Crossref","is-referenced-by-count":27,"title":["En
