[Subthalamic tuberculoma disclosed by hemiballism. Efficacy of antituberculous treatment].

The authors report a case of a 33 years old Moroccan in whom a left hemiballism has revealed a tuberculoma in the right sub-thalamic region. After a year of trial anti-tuberculosis treatment, the hemiballism had almost totally disappeared and the scan picture was significantly reduced. This case unique in its hemiballism etiology, gives way for discussing the present diagnosis as far as intra-cerebral tuberculomas are concerned. Also, this diagnosis is made difficult when one does not have the information of an active visceral tuberculosis. Nevertheless, it is important to have a scan made in order to be able to see the actual picture and particularly to follow the trial anti-tuberculosis treatment.
