T2 hyperintensity in basal ganglia and/or thalami (Pattern 5). Case 1: 15-year-old child with headache, nausea and vomiting. CSF was positive for cryptococcus. T2-weighted imaging (a) demonstrated bubble-like lesions within the basal ganglia (relating to gelatinous pseudocysts), with a relatively smaller component of restricted diffusion (b). Case 2: 14-year-old child with malaise for 2 weeks. CSF was positive for cryptococcus. T2-weighted imaging (c) demonstrated bubble-like lesions within the basal ganglia and thalami, with a relatively smaller component of restricted diffusion (d)
