Ultrasound characteristics of five common soft-tissue tumours in the hand and forearm.
OBJECTIVE
This retrospective investigation reviewed the ultrasound images of 96 benign soft-tissue tumours of the hand and forearm. The aim of the investigation was to determine whether there was any correlation between the ultrasound picture and the histopathological diagnosis.


METHODS
Five common types of benign tumour in the hand and forearm were studied: localized villonodular synovites, haemangiomas, lipomas, nerve tumours, and glomus tumours. Only tumours that had been operated on and sent for histopathological examination were investigated.


CONCLUSIONS
The study found 5 key ultrasound characteristics that were important for differentiating the tumours: existence or not of vessels, existence or not of a capsule, echogenicity, echo structure, and pattern of growth. Taking these traits into consideration should make it easier for the examiner to make the right diagnosis with a reasonable degree of accuracy.
