Diagnosis of tumors and inflammatory processes of the nail can be a challenge and non-invasive techniques such as ultrasound and magnetic resonance imaging are becoming popular tools in the characterization of disease. Localization of small tumors can be difficult and lead to multiple surgeries. Extension of tumors can lead to surgical recurrences. Both US and MRI help in the differentiation of tumor types, aid in pre-surgical evaluation, and help in quantifying the amount of inflammation in what might appear as a minimally or non-inflammatory process in a non-invasive manner. These modalities should be strongly considered in evaluation of nail disease leading to better management of nail disease and conditions.
