Left hemiconvulsions occurred in a 13-month-old girl with Hemophilus influe
nzae (H. influenzae) central nervous system (CNS) infection. Tc-99m HMPAO b
rain SPECT showed a focal hyperperfusion area in the right frontal lobe. Th
e patient recovered without complications, and follow-up SPECT revealed mar
kedly improved findings. Tc-99m HMPAO brain SPECT is useful for evaluating
focal convulsions associated with H. influenzae CNS infection.
