We describe here chronological single photon emission computed tomography (SPECT) with N-isopropyl-p-[123I]iodoamphetamine (123I-IMP) of a patient with subacute sclerosing panencephalitis (SSPE) from the early clinical stages. The case, an 8-year-old Japanese girl, was in clinical stage I of the disease on admission. A SPECT study with 99mTc-hexamethylprophyleamine oxime (99mTc-HM PAO) and 123I-IMP revealed hypoperfusion of cerebral blood flow in the bilateral occipital areas and a part of the cerebellum. Initially, no abnormal findings were observed on CT and MRI. Subsequently, however, MRI indicated abnormal signal intensity dominantly in the area of the occipital white matter where hypoperfusion of cerebral blood flow was found by the initial SPECT studies. This abnormal cerebral hypoperfusion appeared to improve after treatment with oral inosiplex and intrathecal interferon-alpha over 6 months of the clinical course. The abnormal signal intensity on the MRI also decreased, but simultaneous cranial CT demonstrated diffuse cortical atrophy and slight ventricular dilatation.
