Carotid body tumour: an enigma that remains

Abstract

<p class="abstract">Carotid body tumour is a form of paraganglioma which arises from the carotid body. This tumour is known for its rich vascular supply mainly contributed by the ascending pharyngeal artery, a branch from external carotid artery. Surgical excision preceded by pre-operatic embolization remains the definitive treatment despite the countless feared complications. We present our experience with a case of carotid body tumour which was embolised prior to surgical excision, unfortunately complicated with a thromboembolic event. This patient was found to have an anatomical variation in the cerebrovascular anatomy known as a fetal posterior cerebral artery which led to a paradoxical PCA infarction post-embolization. We would like to highlight this rare presentation along with its management as there were scarce evidence of this case in the literature.</p>
