Findings of subdural hematoma on Tc-99m-TRODAT-1 SPECT.

摘要

Chronic subdural hematoma (SDH) is difficult to diagnose by clinical manifestations only. Nonspecific neurologic symptoms and signs may lead physicians to make other diagnoses. Although head trauma is the most common cause, it may be considered insignificant or omitted due to its minor initial manifestations. We present a patient with an incidental finding of SDH on Tc-99m-TRODAT-1 SPECT that was originally done for evaluation of his Parkinsonism. This reminds us to be vigilant about other possible coincidental findings on routine examinations.
