Radiology of soft tissue tumors.

Magnetic resonance imaging is the mainstay of diagnostic imaging for soft tissue masses, but plain film, ultrasound, and computed tomography all have roles. A subset of lesions has specific imaging features that enable a confident radiological diagnosis with appropriate clinical correlation. Many soft tissue masses have nonspecific appearances and should be considered for biopsy in a specialist center. When a biopsy is required for definitive diagnosis, careful multidisciplinary planning is essential to avoid contamination of unaffected tissue, leading to recurrence and unnecessary amputations. This article discusses radiological diagnosis, biopsy, and management of the soft tissue mass.
