Background An association between consecutive administrations of macrocyclic gadolinium-based contrast agent (mcGBCA) gadobutrol and linear (L)-GBCA gadopentetate dimeglumine and gadolinium retention in the pediatric brain remains incompletely understood. Purpose To compare signal intensity (SI) changes in the dentate nucleus (DN) on unenhanced T1-weighted imaging (T1WI) in children who obtained mcGBCA gadobutrol with those who had previously received L-GBCA gadopentetate dimeglumine. Material and Methods This retrospective study included 27 children who received L-GBCA gadopentetate dimeglumine followed by mcGBCA gadobutrol and two different control groups matched for age and sex for both periods, each involving 27 individuals with no GBCA administration from January 2010 to January 2020. DN-to-middle cerebellar peduncle (MCP) SI ratios on T1WI were determined. A repeated-measures ANOVA was performed to compare the T1WI SI ratio between children exposed to GBCA in each of the two periods and controls. Pearson correlation analysis was conducted to determine any correlation between SI ratios and confounding parameters. Results T1WI SI ratio was significantly higher in those who had only L-GBCA (1.005±0.087) or subsequent mcGBCA gadobutrol (1.002±0.104) than in control groups 1 (0.927±0.041; P<0.001) and 2 (0.930±0.041; P=0.002), respectively, but no significant difference of the T1WI SI ratio was noted between L-GBCA period and subsequent mcGBCA gadobutrol period ( P=0.917). T1WI SI ratios and the L-GBCA administration number revealed a modest but significant correlation (correlation coefficient=0.034; P=0.016). Conclusion Previous administration of gadopentetate dimeglumine is associated with increased T1WI SI in the DN, while subsequent administration of gadobutrol does not demonstrate any additional SI increase in the pediatric brain.

The unique pathological findings of a case of congenital familial hyperbilirubinemia are presented. The patient (Case 3 of Crigler and Najjar's original report), although severely jaundiced, had developed normally without evidence of neurological disease until 15½ years of age. He then developed a progressive neurological deterioration which was clinically similar to infantile kernicterus. At autopsy most of his organs showed extensive intra- and extracellular deposition of bile pigment, particularly the renal papillae, atrial endocardium, intestinal mucosa, Kupffer cells of the liver, and the perivascular adventitia. Although no pigment was found in the central nervous system, there was striking neuronal loss and gliosis of the thalamus. Moderate neuronal loss was found in the putamen, caudate nucleus, dentate nucleus, and red nuclei. No histopathological changes were found in the hippocampus or cerebral cortex. It is suggested that the patient suffered from a late onset of "kernicterus" with involvement, in this older patient, of regions of the nervous system somewhat different from those in infantile kernicterus.
