CT and MR imaging for detecting neoplastic invasion of esophageal inlet

Figure 3 Axial contrast-enhanced CT of a 67-year-old man with direct esophageal inlet involvement by laryngeal carcinoma. A: Axial contrast-enhanced CT at the supraglottic level of a left-sided laryngeal tumor mass (T) invading both aryepiglottic folds, both false cords, laryngeal ventricles and paraglottic spaces. Arrows point to the destruction of thyroid cartilages. Arrowhead points to the intact arytenoid cartilage; B: Axial contrast-enhanced CT at the esophageal inlet level of a tumor mass extending to the subglottic region, eroding the cricoid cartilage (C) and invading the esophageal inlet (EI).
