Learning objectives

- To be familiar with ultrasound images of important acute musculoskeletal pathology - To be informed of potential pitfalls that could lead to misdiagnosis which may lead to serious complications

Background

- There are a number of acute musculoskeletal pathologies which require accurate diagnoses. On ultrasound, such pathological findings may resemble normal musculoskeletal structures or other less clinically critical abnormalities. - Important traits of acute musculoskeletal pathology in ultrasound images will be exemplified by study cases.

Imaging findings OR Procedure Details

- The literature review of acute musculoskeletal pathology reveals that many of the acute musculoskeletal pathology ultrasound images may resemble the ultrasound images of other abnormalities. - Acute musculoskeletal pathologies and their common misdiagnoses, along with recommended solutions and precautions, are presented and discussed below. 1. Cellulitis versus necrotizing fasciitis Cellulitis refers to edema and hyperemia of subcutaneous tissue and skin which is primarily clinical diagnosis. However, in case of failed antibiotic treatment or suspected complication or inconclusive diagnosis, imaging can provide a crucial information...

Conclusion

- Knowledge of important acute musculoskeletal pathology and their ultrasound features can help preventing misdiagnosis and complications.
