Objectives: After studying the article entitled “The Utility of Musculoskeletal Ultrasonography in Diagnosing Pyomyositis: A Comparison With Surgically and Conservatively Treated Cases,” you will be able to:
Describe the stages of pyomyositis
Identify the strengths and limitations of imaging modalities for diagnosing pyomyositis
Recognize clinical characteristics of pyomyositis
Pyomyositis commonly involves the: Distal, large muscles of the lower limb Distal, small muscles of the lower limb Proximal, large muscles of the lower limb Proximal, small muscles of the lower limb
What is the sensitivity of magnetic resonance imaging in diagnosing acute musculoskeletal infections? 100% 97% 95% 92%
In this study, what characteristic was identified in 99% of cases? Elevated white blood cell History of trauma History of fever Signs of inflammation
What was the most common pathology diagnosed with pyomyositis on musculoskeletal ultrasound (MSK-US) scanning? Cellulitis Effusion Osteomyelitis Bursitis
What stage of pyomyositis has sonographic features of diffuse muscle swelling with edema and diffuse hyperemia? Invasive Transitional Suppurative Late
What stage of pyomyositis is characterized by muscle abscess formation? Invasive Transitional Suppurative Late
In this study, considering manipulation as a form of trauma increased the prevalence of trauma to what percentage of the sample size? 78% 53% 89% 99%
Which muscle group was affected with pyomyositis in 24% of the cases in the study? Quadriceps Gluteals Shoulder girdle Hamstrings
What was the reported sensitivity of MSK-US for conservatively treated cases of pyomyositis in this study? 100% 95% 97% 92%
In which stage of pyomyositis was sonography determined to have the greatest ability to establish a diagnosis of pyomyositis? Invasive Transitional Suppurative Late
