The angiographic and brain scan findings in acute non-herpetic encephalitis

Acute Hemorrhagic Leukoencephalopathy

Two patients with acute hemorrhagic leukoencephalopathy, one of which was pathologically proven, were serially studied with CT scanning. Both patients showed marked distinctive low density white matter changes throughout both hemispheres, which correlated with clinically involved areas. One patient recovered from the disease, perhaps due to steroid treatment, and showed slow but complete resolution of CT scan changes. We feel that CT scan findings significantly help in the diagnosis of this disease, which may be amenable to early treatment with steroids.

MRI of mumps encephalitis: comparison with CT evaluation

The evaluation of a patient with mumps encephalitis by computed tomography (CT) and magnetic resonance (MR) imaging is reported. Correlation of findings on MR and CT in relation to clinical symptoms is presented. MR was found to be more sensitive in the number of lesions detected (11) as compared to CT (3). Thus, it seems that MR imaging may be a sensitive diagnostic adjunct in cases of suspected viral encephalitis.
