Bilateral subdural hematomas detected on brain SPECT.

Extra-axial pathology is occasionally detected or suspected during brain SPECT imaging performed to evaluate cerebral dysfunction. In this case, Tc-99m bicisate (Neurolite) brain SPECT was the initial examination undertaken to evaluate cerebral dysfunction in an 86-year-old man with seizures, confusion, and headache. The brain SPECT demonstrated relatively normal bilateral brain activity. However, an elongated and markedly indented appearance of both frontoparietal regions (predominantly on the right side) were regarded as highly suspicious for bilateral subdural hematomas. This suspicion was confirmed on subsequent CT imaging, and the collections were surgically evacuated.
