Information on long-term clinical course and immunotherapies is scarce or has not been reported in detail in the literature. Objective: Aims of our study were to assess the incidence of NICE lesions in patients after cerebral EVT over a period of more than 12 years, describe clinical and EVT characteristics, and immunotherapies applied.<h4>Methods</h4>A retrospective chart review of all patients treated by endovascular therapy for symptomatic or asymptomatic aneurysms at the University Hospital of AugsbuTherapeutic advances in neurological disorders17562864211072372https://www.ebi.ac.uk/biostudies/studies/S-EPMC8808010biostudies-literatureIncidence, clinical spectrum, and immunotherapy of non-ischemic cerebral enhancing lesions after endovascular therapy.PMC8808010Welzel JMuller MBayas AMaurer CChrist MBerlis AAnn Gerdes LErtl MNaumann MSeelos KJoachimski FfalseIncidence, clinical spectrum, and immunotherapy of non-ischemic cerebral enhancing lesions after endovascular therapy.<h4>Background</h4>Symptomatic and asymptomatic delayed non-ischemic cerebral enhancing (NICE) lesions in magnetic resonance imaging (MRI) have been reported as a rare complication after endovascular therapy (EVT) in recent years with incidence rates between 0.05% and 0.9% in most studies.
