Cortical lesions within or in close proximity to the retrochiasmal visual pathways may also present in a manner that mimics migrainous visual phenomena and, in some cases, may be too small to manifest with a visual field defect on formal testing. We present 4 patients (3 females and 1 male) with an average age of 48.5 (range 28\u201367) years who had migraine-like visual disturbances related to a right temporal meningioma, occipital cavernoma, occipital lobe infarction, and demyelination in the optic radiations, which was the presenting sign of multiple sclerosis. No patient underwent neurosurgical intervention, and 1 patient (occipital lobe infarct) had complete resolution of the symptom after initial presentation. All patients had normal visual fields at follow-up and no thinning evident on optical coherence tomography. Our cases emphasize the importance of a history in assessing patients with transient positive visual phenomena and identify pathology that may present without visual field defects. Clinical features that should raise a doubt about a diagnosis of migraine visual aura include the absence of headache, brief visual disturbance lasting &amp;#x3c;5 min or those lasting &amp;#x3e;60 min, and age &amp;#x3e;40, especially with no past medical history of migraine. <\/jats:p>","DOI":"10.1159\/000517792","type":"journal-article","created":{"date-parts":[[2021,7,19]],"date-time":"2021-07-19T21:02:26Z","timestamp":1626728546000},"page":"653-658","source":"Crossref","is-referenced-by-count":3,"title":["Migraine-Like Positive Visual Phenomena Related to Focal Cortical Lesions with Undetectable Visual Field Defects"],"prefix":"10.1159","volume":"12","author":[{"given":"Amir","family":"Vosoughi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Micieli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4911-9152","authenticated-orcid":false,"given":"Jonathan A.","family":"Micieli","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2021,7,19]]},"container-title":["Case Reports in Ophthalmology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/517792","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/517792","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:07:53Z","timestamp":1745420873000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000517792"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,7,19]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2021,9,7]]}},"URL":"https:\/\/doi.org\/10.1159\/000517792","archive":["Portico"],"relation":{},"ISSN":["1663-2699"],"issn-type":[{"value":"1663-2699","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,7,19]]}}}
