Chronic subdural haematoma presenting as freezing of gait

In this report, we describe a case of freezing of gait (FOG) in a patient with chronic subdural haematoma (CSDH). An 81-year-old patient presented with progressive FOG about 6 weeks after a minor head trauma. MRI revealed CSDH in the left hemisphere, resulting in a marked compression of the hemisphere. His FOG disappeared after neurosurgical evacuation of the haematoma. It is suggested that the subdural haematoma in his left frontal cortices caused FOG. CSDH should be considered as a differential diagnosis when FOG develops after a head trauma in elderly patients, and prompt evaluations including neuroimaging and timely neurosurgical intervention are required.
