CECT scan of neck showing irregular lesion along the medial margin of left vocal cord at the junction of anterior one third and posterior two thirds. There is thickening of left true vocal cord with loss of paraglottic fat, suggestive of a neoplastic lesion. The normal paraglottic fat on right side is seen as black area just deep to the thyroid cartilage (seen as white). The airway is seen as black oval structure
