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…
Hand and Wrist The complex anatomy of the hand and wrist presents interesting imaging challenges regardless of the modality selected. Both detection and classification of pathology can be difficult. This…
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…
Soft Tissue Tumors in a Large Referral Population: Prevalence and Distribution of Lesions by Age, Sex, and Location KEY CONCEPTS A correct histologic diagnosis is reached on the basis 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…
Spinal Instrumentation The goals of spinal instrumentation are to provide stability, reduce deformity by restoring and improving anatomic alignment, and reduce pain. Spinal instrumentation techniques have expanded dramatically over the…
