In this case report, contrast extravasation due to deterioration of the blood-brain barrier after ECT mimicking subarachnoid hemorrhage (SAH) on magnetic resonance imaging (MRI) is discussed. Case Description: A 70-year-old male patient who underwent ECT presented with sulcal hyperintensities suggesting subarachnoid hemorrhage on fluid-attenuated inversion recovery sequence of MRI obtained after ECT. However, there was no evidence to suggest SAH on nonenhanced brain computed tomography. Conclusion: It should be kept in mind that patients may have contrast extravasation due to deterioration of the blood-brain barrier after ECT, and other alternative methods should be used for the diagnosis of SAH in these patients, not MRI. © 2018 Elsevier Inc.Elsevier Inc.2018Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/14120https://doi.org/10.1016/j.wneu.2018.03.0631878-8750enWorld Neurosurgeryinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14120
