Abstract
Although the combination of MR imaging findings and clinical evidence of hypertension may suggest the diagnosis of posterior reversible encephalopathy syndrome (PRES), MR imaging findings with only involvement of the medulla oblongata pose a diagnostic dilemma. In the cases presented here, we demonstrated MR imaging findings of a presumed brain stem (medulla oblongata) variant of PRES and emphasized the diagnostic value of diffusion-weighted imaging (DWI).
摘要
尽管磁共振成像（MR）表现与高血压的临床证据相结合可能提示后可逆性脑病综合征（PRES）的诊断，但仅累及延髓的MR成像表现会带来诊断难题。在本文所展示的病例中，我们呈现了推测为PRES脑干（延髓）变异型的MR成像表现，并强调了扩散加权成像（DWI）的诊断价值。
