Sonoelastography, B-mode sonography, and color Doppler sonography findings of pleomorphic adenomas and Warthin tumors of parotid gland

Abstract

Objectives: This study aims to investigate the sonoelastography SE , B-mode sonography, and color Doppler sonography findings of the pleomorphic adenomas and Warthin tumors of the parotid gland. Patients and Methods: A total of 84 parotid masses 23 pleomorphic adenomas, 25 Warthin tumors in 72 patients 37 males, 35 females; mean age 59 years; range 30 to 79 years were retrospectively analyzed. For each lesion, B-mode sonography, color Doppler sonography, and SE images were evaluated. Vascularity and elasticity scores of the tumors during color Doppler sonography and SE examinations were calculated by 4-scoring method. Results: Lobulated contour and cystic areas were more common in the pleomorphic adenomas and Warthin tumors during the B-mode sonography examination p<0.05 . Peripheral vascularity was common in more than half of the pleomorphic adenoma patients, whereas central or mixed vascularity was seen in a large group of the Warthin tumor patients p<0.05 . The mean scores on color Doppler sonography examination were 1.13±0.81 for pleomorphic adenomas and 1.96±0.97 for Warthin tumors p<0.05 . The mean scores on SE examination were 2.69±0.70 for pleomorphic adenomas and 1.83±0.63 for Warthin tumors p<0.05 . Score 1 on SE examination was found in three of five Warthin tumor patients with peripheral vascularity on color Doppler sonography. Conclusion: B-mode, color Doppler and elastography examinations by sonography provide some helpful findings in the differentiation of pleomorphic adenomas and Warthin tumors.

Parotis bezi pleomorfik adenomları ve Warthin tümörlerinin sonoelastografi, B-mod sonografi ve renkli Doppler sonografi bulguları

Abstract

Amaç: Bu çalışmada parotis bezi pleomorfik adenomları ve Warthin tümörlerinin sonoelastografi SE , B-mod sonografi ve renkli Doppler sonografi bulguları araştırıldı.Hastalar ve Yöntemler: Yetmiş iki hastada 37 erkek, 35 kadın; ort. yaş 59 yıl; dağılım 30-79 yıl toplam 84 parotis kitlesi 23 pleomorfik adenom, 25 Warthin tümörü retrospektif olarak incelendi. Her lezyon için B-mod sonografi, renkli Doppler sonografi ve SE görüntüleri değerlendirildi. Renkli Doppler sonografi ve SE incelemeleri sırasında tümörlerin damarlanması ve elastisite skorları 4 skor yöntemiyle saptandı.Bulgular: B-mod sonografik değerlendirme sırasında, pleomorfik adenomlar ve Warthin tümörlerinde, lobüle sınırlı ve kistik alanlar daha yaygındı p
