MRI features of soft-tissue lumps and bumps

Superficial soft-tissue lesions are frequently encountered by radiologists in everyday practice. Characterization of these soft-tissue lesions remains problematic, despite advances in imaging. By systematically using clinical history, anatomical location, and signal intensity characteristics on MRI images, one can determine the diagnosis for the subset of determinate lesions that have characteristic clinical and imaging features as well as narrow the differential diagnoses for lesions with non-specific or indeterminate characteristics. In this review, a spectrum of histologically proven benign and malignant superficial soft-tissue lesions from a single institution will be presented. In addition, a few tumour-like conditions will be included as they can be encountered during imaging of soft-tissue masses. (C) 2014 The Royal College of Radiologists. Published by Elsevier Ltd.
