A 61 year old man, without neurological history, has a coma after a facial concussion. While the consciousness is improving, parkinsonism feature is observed with tremor at rest, rigidity and bradykinesia. From the radiological point of view, hematoma of right and left basal ganglia is observed on C.T. Scan performed 6 hours after cranial trauma. The authors study the role of these 2 hematomas in genesis of parkinsonism through literature data and they bring a mean piece in pathophysiology of parkinsonism reported in boxers.
