MRI in acute disseminated encephalomyelitis

Abstract: A retrospective analysis of CT and MRI studies in 12 patients with a clinical diagnosis of acute disseminated encephalomyelitis (ADEM) was performed. MRI was the definitive modality for the assessment of the lesions of ADEM: all patients had abnormalities consistent with the clinical diagnosis. Ten had abnormalities in the brain, three spinal cord lesions, and three showed evidence of optic neuritis. CT was normal in 6 of the 7 patients in which it was performed.

“…Magnetic resonance images (MRI) findings in ADEM have been reported in several studies; typical ADEM lesions are multifocal white matter lesions in the cerebrum [1,2], and cerebral cortical involvement has also been reported [1,[3][4][5][6]. In this case report, we describe an ADEM patient with medial temporal cortical lesions mimicking acute limbic encephalitis on MRI.…”

“…Concerning the limbic lesions, only one case of acute hemorrhagic leukoencephalitis, a more severe form of ADEM, has been reported to have features mimicking herpetic encephalitis [12]. Although multifocal white matter lesions are found in ADEM patients, several ADEM patients have been reported with cerebral cortical lesions [1,[3][4][5][6], suggesting that medial temporal lobes could be affected in patients with ADEM.…”

“…Embora a destruição da mielina pelos monócitos tenha sido apontada como o evento primário na ADEM, tem-se demonstrado também o papel da lesão vascular, secundária à deposição de imunocomplexos circulantes e ativação do complemento, na patogênese da doença. Postula-se que a alteração inicial seria dano endotelial mediado por complemento, levando à desmielinização perivascular, com lesão tissular ocorrendo como fenômeno secundário 1,2,6 . O diagnóstico imageológico da ADEM progrediu bastante com o advento da RM, uma vez que a TC é exame pouco sensível para a avaliação de lesões desmielinizantes.…”
