Traumatic bilateral basal ganglia bleed is extremely rare. It is defined as a hemorrhagic lesion located in the basal ganglia or neighboring structures such as the internal capsule and the thalamus. This report describes a 37-year-old man who had large bilateral basal ganglia hemorrhage (BGH) with subdural hematoma and traumatic subarachnoid hemorrhage. With regards to an etiology of bilateral hemorrhage of the basal ganglia, we could not disclose any possible cause except head injury in spite of full diagnostic work-up. Our final diagnosis was bilateral traumatic BGH (TBGH). The pathomechanism of such injuries is still not clear and it is proposed to be due to shear injury to the lenticulostriate and choroidal arteries. Rather than any features of the TBGH itself, duration of coma and/or associated temporal herniation predicted slower recovery and worse outcome. Bilateral TBGH is an extremely rare entity, compatible with a favorable recovery, if not associated with damage to other cortical and subcortical structures and occurring in isolation. TBGH can be considered as a marker of poor outcome rather than its cause. The BGHs seem to be hemorrhagic contusions resulting from a shearing injury, due to high velocity impact.
