Oedema of larynx. Artwork of a transverse (axial) section through a larynx (seen from above) with and without swelling. The bottom image shows a healthy larynx. The top image shows oedema (swelling caused by fluid accumulation). The swelling is in the mucous tissue of the epiglottis, just above the vocal folds (vocal cords, seen at bottom). Swelling such as this is known as laryngeal oedema and oedema glottidis. If the swelling increases, it could block the airway and can be fatal. As well as the soft tissue (red), throat cartilage (blue) is also shown. For a coronal view of this condition, see image C016/6528.
