Oromandibular dystonia secondary to radiation therapy: a description of 2 cases.

CSF findings resemble those in other infections of the central nervous system. Appearance of a focal neurological deficit in a case of TBM should suggest secondary neurovascular impairment, even in patients who are receiving appropriate treatment. Nevertheless, as this case description shows, a cerebral infarct with an atypical location may be a form of presentation of TBM, which should be considered when vascular symptoms appear in association with meningeal syndrome and CSF changes. Rapid discovery of a positive PCR test for M. tuberculosis will permit use of a specific and early treatment. In some cases, such as the one described here, this may prevent the appearance of other complications and residual symptoms.
