Fatal Infarction of Brain in Migraine

Abstract

(see Fig.). Occasional papillary proliferations and solid cell masses were present. The abnormal tissue tailed off peripherally into foetal thyroid, though there was a very incomplete, inconspicuous fibrous layer between the tumour and normal foetal thyroid. Centrally the tumour had grown through the eroded tracheal ring and into the submucosa of the trachea, causing the latter to be greatly thickened. The mucosal epithelium itself was absent on the affected side. The presence of colloid-filled vesicles in the tracheal portion of the tumour confirmed the thyroid origin. The lung showed alveolar distension with rupture of some alveolar walls.
