Migraine-like headache in subjects with isolated Lambl's excrescences: a case series and literature review
Abstract
Abstract Aim Lambl’s excrescences are mobile, thin, fibrinous connective tissue strands typically found on left-sided cardiac values. Migraine is positively associated with structural cardiac anomalies. However, it remains unclear whether Lambl’s excrescences are associated with migraine. Methods Retrospective review of 182 inpatients with Lambl’s excrescences confirmed by transesophageal echocardiogram in Chinese PLA General Hospital since January 2010. Among them, those with isolated Lambl’s excrescences presented with migraine-like headache were included. We collected information on the demographics and clinical profiles of all participants, and performed follow-up visits. Results A total of 8 patients presented with migraine-like headache among 15 patients with isolated Lambl’s excrescences. They included 2 men and 6 women, with an average age of 44.63 ± 12.24 years. Among these patients, 3 had visual aura, and 6 manifested infarct-like lesions on magnetic resonance imaging, of which 2 developed lesions after first visit. During follow-up, 4 patients suffering from intervention for Lambl’s excrescences dramatically reduced headache recurrence compared to the other 4 patients only receiving migraine preventive medications. Conclusions This study supports the hypothesis that microemboli from isolated Lambl’s excrescences could cause migraine-like headache. And intervention for Lambl’s excrescences may be crucial for preventing headache recurrence. STRENGTHS AND LIMITATIONS…
