Imaging of hand and wrist cysts: a clinical approach.

OBJECTIVE
Ganglion cysts are common hand masses. This article will answer three questions that the radiologist is often asked: A mass is palpable; is it a cyst? Pain or neurologic symptoms are present; are they related to a cyst? Surgery is being considered; where precisely are the cyst and its origin located?


CONCLUSION
Ultrasound is often sufficient for assessing typical cysts. MRI is performed when atypical features or neurologic symptoms are present and in specific preoperative settings.
