HM-PAO SPECT Brain Scintigraphy in a Patient with the Syndrome of Chronic Encephalitis and Epilepsy

ABSTRACT

Both interictal Tc-99m hexamethyl-propyleneamine oxime single photon emission computed tomography (HM-PAO SPECT) brain scintigraphy was done in a patient with the syndrome of chronic encephalitis and epilepsy. The low density area in the temporo-occipital lobe on brain CT scan revealed decreased radioactivity during interictal state and it was reversed to increased radioactivity during ictal state on HM-PAO SPECT brain imaging. In authors' opinion, ictal and interictal Tc-99m HM-PAO SPECT brain scintigraphy could be a safe and convincing study for Searching epileptogenic foci.
