Stroke in Association with Thyroid Goitre: A Case Report.

Ischaemic stroke secondary to isolated internal carotid artery thrombus without risk factors is uncommon. A 55-year-old woman presented to the acute stroke unit with acute right middle cerebral artery territory infarction secondary to right internal carotid artery occlusion. There were no risk factors for cerebrovascular disease, but mediastinal imaging showed the presence of a large retrosternal goitre which was displacing the mediastinal structures including the brachiocephalic and common carotid artery. Intraluminal thrombus is visible in the displaced innominate artery and is the underlying cause for the stroke in our patient. This case highlights the importance of appropriate imaging of the mediastinum in cases with thyroid goitre. Crown
