[Ultrasonography in diseases of lymph nodes and soft tissues of the neck].

A study of 55 patients affected by neoplasia of the head and neck or clinically evident laterocervical swellings was carried out in order to evaluate the diagnostic value of ultrasonography in the study of cervical lymph nodes and soft tissues, excluding thyroid or salivary pathologies. The analysis of results confirmed that, in line with previously published findings, ultrasonography is a reliable method of diagnosing lesions and correctly identifying the affected organ, but then it is considerably less reliable in defining the type of lesion. In view of this, it is reasonable to propose a more widespread use of ultrasonographically guided needle biopsy which, in addition to being a rapid and non-traumatic method, would allow precisely target samples to be taken from those lesions with a doubtful or unusual clinical or ultrasonic appearance.
