Parkinsonism Secondary to Chronic Subdural Hematoma Showing in the TRODAT-1 Scanning

Chronic subdural haematoma (CSDH) is an encapsulated collection of old blood, mostly or totally liquefied and located between the dura mater and the arachnoid mater. A subdural hematoma can cause parkinsonian symptom as a result of compression on the mid-brain, but the actual cases are rarely reported. We herein reported a case of CSDH discovered incidentally by Tc-99m TRODAT-1 SPECT during a work-up for Parkinson’s disease. Surgical evacuation of the hematoma of this patient resulted in a partial recovery. This report recapped the multifaceted possibility of parkinsonism which necessitated a thorough and detailed assessment.
