[Intramedullary tuberculoma: a case report].
A fifty-year-old Portuguese man presented with a six-month history of low back pain, which initially was mechanical and slowly became inflammatory. Secondarily, he complained of right atypical sciatalgia. He did not report any fever, loss of weight, cough nor personal or familial history of tuberculosis. General examination was normal. Neurologic examination showed weakness of the extensors of the right leg, with a symmetric increased reflexes of the lower extremities suggesting a pyramidal syndrome without Babinski's sign. Laboratory data were normal as well as chest radiographs. Dorsolumbar gadolinium enhanced MRI revealed an intramedullary ringlike enhancing mass at T12 level. Lumbar puncture showed 11 WBC/mm3 (95 p. 100 lymphocytes), a normal protein and glucose content. PCR and culture for Mycobacterium tuberculosis were negative. Within a few days, he developed meningoencephalitis with fever, CSF examination revealed then 360 WBC/mm3 (65 p. 100 lymphocytes and 17 p. 100 neutrophils), a protein content of 7 g/l and a glucose level of 1.7 mmol/l. The clinical picture was then suggestive of tuberculosis and a specific therapy with rifampin, izoniazid, pyrazinamid, ethambutol and steroids was started. Clinical improvement and a second CSF culture that revealed one month later Mycobacterium tuberculosis complex confirmed this diagnosis. Ten months later, the patient was asymptomatic with a normal MRI. To our knowledge, this is the first total recovery of an intramedullary tuberculoma on medical therapy alone, confirmed by MRI normalization. We reviewed also 19 recent cases of tuberculomas in the literature, intending a therapeutic attitude when discovering an intramedullary ringlike enhancing mass on MRI.
