“…Following exclusion of 53 items, 109 items comprising 504 cases were reviewed. A total of 53 items were labeled as “Cases—Structural” (70 individual case reports in total) 12–64 (Table ), 34 as “Cases—Nonstructural” (50 individual case reports in total) 65–98 (Table ), and 19 as “Groups” (384 cases in total) 99–117 (Table ). In addition, from two case series of three patients, 118,119 three cases were included in “Cases—Structural,” and three in “Cases—Other.” In one case, additional information was gathered from a previous report of the same case 38,120 …”

Objective To determine if a clinical presentation indistinguishable from migraine can occur due to an underlying condition or pathology, that is, "symptomatic migraine." Background It is currently not clear whether migraine truly can be caused by an underlying condition or pathology. Characterization of the etiology and clinical features of possible symptomatic migraine is of significant clinical importance and further may help elucidate the pathophysiology of migraine. Methods We devised operational diagnostic criteria for “symptomatic migraine” and “possible symptomatic migraine” requiring strong evidence for a causal relation between underlying cause and migraine symptoms adhering strictly to diagnostic criteria. PubMed was searched for case reports of symptomatic migraine from inception to March 2020. Only articles published in English or German were included. No restrictions were placed on study design. Relevant references in the articles were also included. Papers were systematically reviewed by two independent reviewers for detailed clinical features of migraine as well as the proposed underlying conditions and the effects of treatment of these conditions. Results Our search retrieved 1726 items. After screening, 109 papers comprising 504 cases were reviewed in detail. Eleven patients with migraine with aura (MWA) fulfilled our working criteria for symptomatic migraine, and 39 patients fulfilled our criteria for possible symptomatic migraine. The most common etiologies of symptomatic migraine were arteriovenous malformations, carotid stenosis, dissection or aneurysm, brain infarctions, meningioma, and various intra‐axial tumors. Conclusions Symptomatic MWA, indistinguishable from idiopathic MWA, may occur due to cortical lesions or microembolization. We found no clear evidence supporting the existence of symptomatic migraine without aura although we did identify possible cases. Our findings are limited by the available literature, and we suggest that prospective studies are needed.

“…Therefore, for every patient with a headache (especially a migraine-like feature), every new, additional symptom (auditory, visual, and/or encephalopathic) should raise suspicions and result in referral of the patient for further diagnostics towards Susac's syndrome [40].…”
