Ventricular visualization during 99Tc(m) pertechnetate brain scanning is probably due to increased permeability of the blood spinal fluid barrier to the technetium ion. It has been shown by others that various disease states affect the permeability of the blood spinal fluid barrier in adults and these permeability changes may be even more striking in infancy. The ventricular visualization noted in 4 patients was due to intraventricular infection in 3 (proven in 2, suspected in 1) and secondary to hyperthermic or anoxic damage to the CNS in 1. The presence or absence of ventricular visualization seems to bear a direct relationship to the severity of the intraventricular infection (as determined by CSF analysis).
