INTRODUCTION: movement disorders have been associated with deep brain lesions. This study was performed to describe the frequency and characteristics of movement disorders in patients with intracranial tuberculomas.
METHODS: patients admitted consecutively between 1989 and 2004 to the Neurology Service of Eugenio Espejo Hospital (Quito, Ecuador), with a diagnosis of intracranial tuberculomas. All patients were examined clinically, and laboratory tests and imaging studies performed. Follow-up continued up to one year after the tuberculosis treatment was completed. A nested case-control analysis was performed to compare clinical characteristics, number and location of tuberculomas, between cases with movement disorders and controls.
RESULTS: forty-nine patients with tuberculomas (31.7±20.5 years; males 53.1%) were studied. We found 16 cases (32.6%; 95%CI=19.9% - 47.5%) of movement disorders: chorea (n=7; 43.8%), tremor (n=5; 31.3%), dystonia (n=3; 18.8%) and myoclonus (n=1; 6.3%). Most cases (87.6%) developed early (10.4±5.2 days of hospitalization). On admission, patients with movement disorders showed higher severity of the illness than controls (68.7 vs. 30.3%; p=.01), along with greater motor impairment (75.0 vs. 39.4%; p=.01) and sensitivity impairment (43.8 vs. 9.1%; p=.01). The cases showed higher frequency of multiple tuberculomas (68.7 vs. 36.4%), with deep brain deep (31.3 vs. 21.2%) and more severe motor impairment (25.0 vs. 12.1%).
CONCLUSIONS: our results suggest a causal relationship between tuberculomas and movement disorders. Deep location and multiple tuberculomas may increase the risk of develop movement disorders.
