Vascular causes of dysphonia: A case series with different etiologies

Research output: Contribution to journalArticlepeer-review

Abstract

Dysphonia is a frequent and often disabling condition that can be caused by a multitude of circumstances. Differential diagnosis of dysphonia comprehends many different etiologies and many causative agents (neoplasms, inflammations, traumatic injuries) that can occur in a large anatomical space (from the encephalic trunk to the upper mediastinum). It is fundamental to remember that vascular etiologies are responsible for some rare cases of dysphonia. In the radiological database of two urban academic hospitals, from 2012 to 2020, we sought patients who underwent CT or MRI for dysphonia, selecting only the ones with an underlying clinically confirmed vascular etiology. We present three emblematic cases with different vascular etiologies: a ductus arteriosus aneurysm, a left internal carotid artery dilatation, a laryngeal arteriovenous malformation (AVM). Vascular causes of dysphonia are rare, but especially in these cases an accurate and prompt diagnosis is fundamental, in particular considering that the underlying cardiovascular anomaly can often pose a higher risk for the patient than the hoarseness itself. Diagnostic imaging plays a fundamental role in detecting the most common causes of dysphonia but it is very important that radiologists take the vascular causes into account so as not to miss them and to obtain a correct diagnosis.
