Methods The clinical data of 70 patients with superficial soft tissue masses from January to November 2008 were retrospectively analyzed. Superficial soft tissue masses was diagnosed by the surgery and biopsy. The sonographic features, including the location, morphology, size, internal echo, boundary, relationship with peripheral tissues, longitude to transverse ratio (L/T), and the vascularity, were observed. Results The results of sonographic examination showed that 100% superficial masses could be found. Benign masses included lipoma, sebaceous cysts, synovial cysts, nerve sheath tumors, haemangioma, foreign body granulomas, etc. Malignant soft tissue tumors included fibrous sarcoma and metastatic neoplasms. Conclusion Color Doppler ultrasonography can precisely diagnose the presence, localization and the physical characters of superficial soft tissue masses. It is an excellent modality to diagnose the benign or malignant masses by analyzing the boundary, configuration, internal echo and vascularity of the masses.

Methods We retrospectively analyzed the clinical data of 105 patients with thyroid nodules confirmed by pathology between 2007 and 2010 and summarized the ultrasonography results. Results Among the 105 cases, 71 were benign nodules and 34 were malignant tumors. The overall diagnostic accordance rate was 81.9% with 18 cases (17.1%) of misdiagnosis. Conclusion Ultrasonography is the first imaging modality for thyroid nodule examination, but it is limited in the diagnosis of microcarcinoma and in distinguishing malignant from benign nodules in the same thyroid.
