CLOCC in an adolescent with MIS-C and SARS-CoV-2.. MR image of the brain demonstrates a nonspecific focus of increased signal in the splenium of the corpus callosum on DWI sequences at b=1000 s/mm2 (black arrow, A) with associated loss of signal on apparent diffusion coefficient maps (white arrow, B) corresponding to restricted diffusion. The apparent diffusion coefficient for the lesion is 0.44 × 10−3 mm2/s. This lesion corresponds to a faint focus of abnormal increased signal on T2WI spin-echo sequences (black arrowhead, C). The lesion also demonstrates a lack of contrast enhancement on T1WI postcontrast thin-section image (D) and absent susceptibility, suggesting absent hemorrhage on SWI (E). The imaging findings suggest a cytotoxic lesion of the corpus callosum. Follow-up DWI (F) and ADC maps (G) with T2WI (H), T1WI (I), and SWI sequences (J) after 2.5 months demonstrate resolution of the lesion after therapy.
