Neonatal seizures can be difficult to classify according to partial vs
generalized onset based on clinical appearance, electroencephalogram
(EEG) or other adjunctive imaging techniques. Single-photon emission c
omputed tomography (SPECT) has proven to be useful in adults; however,
its use is limited in the paediatric age group, particularly in neona
tes. A case of a 12-d-old infant with intractable seizures is reported
, on whom an interictal Tc-99m HMPAO SPECT showed an area of hypoperfu
sion in the left temporal cortex, whereas the ictal SPECT revealed pro
minent hyperperfusion in the same area. The EEG of the infant demonstr
ated generalized epileptiform activity, while computed tomography and
magnetic resonance (MR) imaging findings were normal. This case indica
tes that the use of SPECT may provide valuable data in evaluation of n
eonatal seizures, particularly with poorly localized EEG changes and n
ormal MRI scans.
