Role of CT in occult and submucosal laryngeal masses

ABSTRACT

CT was the prime radiologic examination for 20 patients [their ages ranged from 25-70 years] with submucosal laryngeal lesions. Hoarseness of voice was the main presenting symptom [14 patients], air way obstruction [3 patients], cervical adenopathy [2 patients], and one case with dysphagia. 16 of patients revealed positive endoscopic visibly focal bulge, and 4 other patients presenting with hoarseness and vocal cord paresis or paralysis had otherwise negative endoscopic findings. Biopsy proved squamous cell carcinoma in 12 which was the essential working diagnosis following CT in 10 patients. The 12 patients with squamous cell carcinoma underwent follow up endoscopic procedures. Other lesions included 3 cases laryngocele, 2 cases chondrosarcoma, and one case each fibrosarcoma, lymphoma, and tuberculous laryngitis
