ABSTRACT

OBJECTIVE:

To present the imaging findings of a patient with diffuse brain injury secondary to intoxication with oral hypoglycemics. CASE REPORT A nine years-old boy presented with generalized tonic-clonic convulsions and decreased consciousness. Laboratory investigation demonstrated blood glucose level of 21 mg/dL. The magnetic resonance imaging showed cortical and subcortical temporo-parieto-occipital areas of high signal on T2 and low signal on T1, with high signal on the diffusion-weighted images and low signal on apparent diffusion coefficient maps.

CONCLUSION:

Cortical and subcortical temporal, parietal and occipital ischemic lesions may be seen in patients with intoxication by oral hypoglycemics.
RESUMO

OBJETIVO:

Apresentar os achados de imagem em um caso de lesão cerebral difusa secundária a intoxicação por hipoglicemiante oral. RELATO DE CASO Menino de nove anos de idade apresentando crises convulsivas tônico-clônicas e rebaixamento do nível de consciência. Exames laboratoriais revelaram glicose sérica de 21 mg/dL. O exame de ressonância magnética revelou lesões corticais e subcorticais têmporoparieto-occipitais, com alto sinal em T2 e baixo em T1, apresentando hipersinal nas imagens ponderadas em difusão e hipossinal nos mapas de coeficiente aparente de difusão.

CONCLUSÃO:

Lesões isquêmicas corticais e subcorticais nos lobos temporais, parietais e occipitais podem ser identificadas em pacientes com intoxicação por hipoglicemiantes orais.
