“…The most widely accepted of the mechanisms proposed so far are Leao's spreading depression, thromboembolic cerebrovascular disease, and epilepsy (1). Recent advances in understanding the pathophysiology of TGA have been possible largely because of functional neuroimaging studies (single photon-emission computed tomography (SPECT), positron-emission tomography (PET) and diffusion magnetic resonance imaging (MRI)) performed acutely during episodes of transient global amnesia (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13). Most of the reported studies seem to indicate the left mesial temporal lobe structures as the main site of the pathologic process in TGA.…”

“…Em 1955, Jacobson 23 relatou pela primeira vez os achados de tomografia computadorizada em HSDI. Atualmente, esse é o exame de eleição para o diagnóstico 50,51 . O achado de uma massa hiperdensa, de formato crescente, semilunar, ao longo da fissura inter-hemisférica com margem medial plana e borda lateral convexa contra o parênquima cerebral é altamente sugestivo de HSDI 33,39 .…”

“…O HSDI apresenta diagnóstico diferencial com hemorragia subaracnóidea; esta produz hiperdensidade somente na região inter-hemisférica anterior, com um contorno tortuoso e se estendendo do calvário ao rostro do corpo caloso. O HSDI produz uma hiperdensidade crescente unilateral que é mais espessa na parte pósterosuperior da fissura, por trás e abaixo do esplênio do corpo caloso 51 .…”
