Objectives: The objective of this study was to evaluate head and neck masses with real-time elastography to differentiate malignant masses.
Materials and methods: Between January 2011 and December 2012, a total of 51 patients with a palpable mass in the neck region were included in this study. Excisional histopathologic data were compared with elastographic results and Doppler ultrasonography.
Results: The study group comprised 27 males (52.9%) and 24 females (47.1%) (mean [SD] age, 41.47 [19.59] y; range, 4-80 y). Fourteen masses were malignant (27.5%) and 37 were benign (72.5%). Comparing the elastographic results of benign and malignant masses, elastographic scores of the malignant masses were significantly higher than those of the benign masses (P < 0.005).The elastographic scores were divided into 2 groups: 34 (91.9%) patients with the diagnosis of benign mass had the score of 1 to 2, whereas 9 (64.3%) patients with the diagnosis of malignant cases had the score of 3 to 4. There was a significant difference between the groups (P < 0.005).However, 2 squamous cell carcinomas (28.6%) and 1 lymphoma (8.1%) were diagnosed with an elastographic score of 1 (Table 2). This showed that even an elastographic score of 1 was not enough to issue a diagnosis of benign masses.
Conclusions: With improvements in the device and increased experience, this modality can become a useful tool for the routine use. However, this modality cannot be used for screening to merely provide additional information about the nature of the masses.
