Brain MRIs of the mother before and after treatment of the meningoencephalitic stage of trypanosomiasis.

<p>(A) Initial brain MRI in January 2013 (axial T1-weighted image after injection of gadolinium chelates) showing perivascular and leptomeningeal enhancement, predominantly in the right corona radiata. (B, C, D) Initial brain MRI in January 2013 (axial fluid attenuated inversion recovery [FLAIR]-weighted images) showing extensive and confluent hyperintensities in both corona radiata and bilateral fronto-parieto-occipito-temporal white matter, internal and external capsules, lenticular nuclei, metencephalon, and middle cerebellar peduncles. Global brain atrophy with enlarged cerebrospinal fluid (CSF) spaces for a 22-year-old patient. (E) Control brain MRI in June 2014, 1 year after treatment (3D-T1 weighted image after injection of gadolinium chelates), showing resolution of the perivascular and leptomeningeal enhancement. (F, G, H) Control brain MRI in June 2014, 1 year after treatment (axial FLAIR-weighted images), showing resolution of the infratentorial and basal ganglia lesions, diminution of the supratentorial white matter lesions (especially capsular lesions), and increased secondary atrophy.</p
