T2 versus T3 glottic carcinoma. Neck CT:There is a mass at the larynx, involving the left vocal cord, extending superiorly to the false cord with partial infiltration of the left paraglottic fat, and inferiorly to the subglottic region. There is thickening of the anterior commissure and the right true cord, suggesting extension across midline to the right. There is sclerosis of the left arytenoid cartilage, which may be involved. There is minimal soft tissue thickening overlying the left lamina of the thyroid cartilage, which is also thinner compared to the right. Very early extralaryngeal extension therefore cannot be excluded; this can be further evaluated with MRI.There is slightly prominent lymph node at left level 2, measuring approximate 10-mm in short axis. A 11-mm node is seen at level 5B. These nodes may be involved.There is a 6-mm cystic lesion at the left tonsil.There is a 9-mm lytic lesion in the left scapular glenoid. It is well marginated, and is likely benign.Degenerative disease of cervical spine is noted.
1. Left laryngeal mass, with supraglottic and subglottic involvement, and extension across midline to the right. There is suggestion of involvement of the left arytenoid cartilage and left thyroid cartilage, and very early extralaryngeal extension. These findings can be further confirmed with MRI.2. Well marginated lytic lesion at the left scapular glenoid, likely benign given its imaging appearance.3. Small left tonsillar cyst.4. Borderline adenopathy at the left level IIA, and level 5B.
