Radiology Key

Masses that May Mimic Soft Tissue Tumors There are a large number of tumor-like lesions of soft tissue. Many of these have a clinical presentation simulating that of a soft…

Superficial Soft Tissues Masses Superficial soft tissue masses are common in clinical practice and the expanding availability of radiologic imaging has increased radiologists’ familiarity with these entities. Superficial soft tissue…

Extraskeletal Osseous and Cartilaginous Lesions The radiologic images of extraskeletal osseous and cartilaginous tumors of the extremities are often sufficiently characteristic to suggest a specific diagnosis. This is particularly true…

Lesions of Uncertain Differentiation The World Health Organization (WHO) previously designated the lesions detailed in this chapter as tumors of uncertain histogenesis, but now refers to them as tumors of…

Vascular and Lymphatic Tumors Angiomatous lesions of the musculoskeletal system are common causes of soft tissue masses, particularly in young patients (1, 2). These lesions, unfortunately, are frequently confused with…

Imaging of Soft Tissue Masses The radiologic evaluation of soft tissue masses has changed dramatically within the last three decades. Prior to the advent of computer-assisted imaging, assessment of a…

Muscle Tumors Muscle tumors of the soft tissue are uncommon. It is difficult to establish their prevalence, but it is estimated that benign muscle tumors make up less than 2%…

Compartmental Anatomy and Biopsy Planning The radiologic staging of a soft tissue tumor is a vital part of a patient’s evaluation (1, 2). As previously noted in Chapter 3, accurate…
