Neuroimaging finding in PA: Male child with PA, symptomatic from day 4 of life, diagnosed at the age of 4 months. A week later a repeat MR study showed more intense T2 signal changes in the involved regions, more prominent in the putamina (A). Although a higher signal intensity of the cortices and basal ganglia on trace DWI (B), with disappearance of low signal of the cortices and presence of higher signal intensity on ADC maps (C) there's pseudonormalization of diffusion restriction.
