Musculoskeletal Infection and Its Mimics: Pearls and Pitfalls (2025)-M4-CMK0421-2025

Video Transcription

Video Summary

The video features several radiologists discussing various aspects of musculoskeletal imaging related to soft tissue and bone infections. Ji-Woo from Beth Israel Deaconess Medical Center describes the imaging characteristics of conditions like cellulitis, ulcers, and sinus tracts, emphasizing the reticular pattern on T1-weighted MRI for cellulitis and differentiating these from conditions like bland edema and thyroid acropathy. Patrick Aboumy from Switzerland discusses necrotizing fasciitis, underlining the urgency for surgical treatment given its serious nature, with imaging playing a crucial role in differentiating from non-necrotizing infections. Cori Ablon highlights septic arthritis, emphasizing the importance of early diagnosis and how imaging can help distinguish septic arthritis from its mimics like rheumatoid arthritis or crystalline arthropathies. Erin Alea and other speakers discuss osteomyelitis, contrasting acute and chronic forms, and emphasizing the significance of MRI in diagnosing confluent low T1 signal patterns. Common pitfalls and diagnostic challenges, such as those presented by Charcot arthropathy and mimics like osteoid osteoma, are also explored, showing how careful interpretation of imaging can aid in accurate diagnosis and management of infections.
