[The appearance of parotid neoplasms on real-time elastosonography].

PURPOSE: To evaluate the features of parotid neoplasms on real-time elastosonography.

METHODS

The elastograms of parotid lesions in 43 patients with 48 neoplasms were analyzed and classified into 5 grades, with pathologic diagnosis as the gold standard for comparision. The data was statistically analyzed with SPSS13.0 software package.

RESULTS

The elastographic grades of most benign neoplasms were I-II, while those of malignancies were III-IV. The elastographic grades of benign and malignant lesions were of significant difference (P<0.05).

CONCLUSIONS

Some typical features of different parotid lesions on elastosonography are found, which are useful for differential diagnosis of parotid lesions.
