Aneurysm of the lingual artery in a patient with fibromuscular dysplasia: A case report
2021
Abstract Lingual artery (LA) aneurysms are particularly rare, and pseudoaneurysms are associated with trauma, infection, and surgical intervention. LA aneurysms can be fatal if not recognised or treated; however, only a few cases of idiopathic LA aneurysms have been reported in the literature, all of which have been described as pseudoaneurysms. To address this knowledge gap in reporting a true LA aneurysm, here, we describe a 55-year-old woman with an idiopathic aneurysm of the lingual artery. The lesion was detected by another department on a computed tomographic angiography of the neck, which was performed as a post-aneurysmectomy evaluation of the right internal carotid artery. The embolisation failed twice, after which we performed an aneurysmectomy of the left atrium. A histopathological examination of the excised aneurysms revealed fibromuscular dysplasia (FMD). Thus, we believe that FMD may be a cause of external LA aneurysms. Our findings will be relevant for oral surgeons and physicians who may consider FMD as a differential diagnosis when treating multiple LA aneurysms.
