Isolated bilateral, large, basal ganglia haemorrhage following a traumatic brain injury: A case report.

Traumatic basal ganglia haemorrhage is rarely seen in clinical practice. Bilateral basal ganglia hematoma without any other cerebral lesions due to trauma is extremely uncommon and has been reported only in a few cases. Although the mechanisms of this condition are unclear, haemorrhagic contusions are thought to arise as a consequence of a shearing strain on cranial blood vessels due to high-velocity forces at the time of the injury. Here we describe a 63-year-old female patient with an isolated bilateral, large, basal ganglia haemorrhage secondary to a road traffic accident. The patient was promptly diagnosed and conservatively treated and had fully recovered after two months.
