Ultrasound and MR findings in tumor and tumor-like lesions of the fingers.

Finger lesions are a frequent problem because of their functional significance and their small size. Because of this, the radiologist has an important role to play in the correct presurgical diagnosis. The aim of this article is to describe the anatomy and the characteristic US and MR findings of the most common tumor and tumor-like lesions of the fingers, and to discuss the differential diagnosis in cases of unspecific or non-diagnostic findings. We present representative cases selected from 62 patients evaluated at our institution, with pathologic correlation.
