Abstract
Brain cytotoxic edema is a neuroradiological sign secondary to variegate diseases ranging from migraine to fulminant Listeria rhombencephalitis. The tempestive identification of its underlying cause is vital for an effective treatment as any delay may be fatal. However, the lack of distinctive imaging biomarkers and the paucity of reports pose a significant challenge in its diagnosis and frequently lead to a misdiagnosis particularly with the more common acute ischemic stroke. Importantly, due to its rarity, mesencephalon midline cytotoxic lesion is likely to remain an underdiagnosed clinical phenomenon, especially if follow up MRI is not performed. Here we report a case of a central, midline, symmetric midbrain cytotoxic edema in a haemodialysis patient with diverse chronic progressive severe cardiovascular risk factors and a newly diagnosed atrial fibrillation. We expand the spectrum of neuroradiological hallmarks associated to terminal renal failure and report a full moon-like mesencephalon midline transient restricted diffusion as a reliable imaging biomarker for the prompt and accurate diagnosis of midbrain cytotoxic edema with the enormous potential of rapidly identifying and effectively treating its causative factors and timely reverse the associated symptomatic.
期刊介绍:
Neurological Sciences is intended to provide a medium for the communication of results and ideas in the field of neuroscience. The journal welcomes contributions in both the basic and clinical aspects of the neurosciences. The official language of the journal is English. Reports are published in the form of original articles, short communications, editorials, reviews and letters to the editor. Original articles present the results of experimental or clinical studies in the neurosciences, while short communications are succinct reports permitting the rapid publication of novel results. Original contributions may be submitted for the special sections History of Neurology, Health Care and Neurological Digressions - a forum for cultural topics related to the neurosciences. The journal also publishes correspondence book reviews, meeting reports and announcements.
