Sonography of soft tissue masses of the neck.

In many clinical conditions, high-resolution sonography and color (power) Doppler sonography can be used as the first-line modality for evaluating cervical soft tissue masses. Cervical cysts, lipomas, paragangliomas, neurogenic tumors, hemangiomas, and lymphangiomas often exhibit characteristic sonographic appearances. Sonography can be used for lymph node assessment, and most salivary gland diseases can be diagnosed sonographically. Sonography can be used to guide needle biopsy of soft tissue neoplasms and lymph nodes. In addition, the relationship between a cervical mass and the great vessels can be evaluated.
