title: Solitary pontine tuberculoma.
abstract: A 66-year-old man, with a history of pulmonary tuberculosis 40 years before admission, complained of headache and dysarthria that lasted for 2 weeks and was followed by diplopia. MRI revealed an isolated nodular lesion in the pons with a marked enhancement mimicking brain tumor and other diseases. Antituberculous drugs were started under the presumptive diagnosis of tuberculoma. The lesion was completely resolved after 9 months of treatment and thus, the final diagnosis was confirmed. An empiric administration of antituberculous drug may be an important and non-invasive diagnostic tool as well as a treatment in such cases.
