1. To learn the key signs for differential diagnosis.
2. To learn about imaging findings and management options.
The diagnosis of infections is based on the presence of clinical symptoms like erythema, swelling and pain. Also, the diagnosis is based on the presence of clinical signs such as fever, tachycardia and shock and laboratory test such as leukocytosis and C protein reactive. However, the clinical symptoms and signs of infection may not be specific, especially in the early stages of the disease. In these cases, Imaging tests play a fundamental role in the early diagnosis of infections and the differential diagnosis. The most important radiological findings for inflammatory and infections soft tissue are: 1/ Intramuscular fluid collections. 2/ Soft tissue air. 3/ Fascial fluid collections and 4/Muscle oedema. Potential causes of these radiological findings are diverse, including, infectious, autoimmune, inflammatory, neoplastic, neurologic, traumatic and iatrogenic conditions. Some of these conditions require prompt medical or surgical management, whereas others do not benefit from medical intervention. Necrotising fasciitis is a rare, life-threatening soft-tissue infection and a medical and surgical emergency that radiologist must know. The presence of gas within the necrotised fascia is characteristic, but may be lacking. The main finding is thickening of the deep fascia due to fluid accumulation and reactive hyperemia. All these findings may be seen in other different conditions. The ability to accurately diagnose these conditions is therefore necessary. Clues to the correct diagnosis and whether a biopsy is necessary or appropriate are often present on the images techniques, especially when they are correlated with clinical features.
1. To explain the key points in the differential diagnosis of common arthropathies.
2. To describe the imaging findings of common arthropathies as they relate to pathophysiology.
Arthropathies are one of the most common health problems and the leading cause of disability in adults. Imaging plays an essential role in their diagnosis and follow-up. Plain films remain the first line imaging tool in the diagnosis and management of arthropathies, whereas MR imaging is essential to ascertain the presence of active inflammation and disruption of intra- and periarticular structures. This interactive presentation focuses on radiological features of common (and several less common) arthropathies and how they help in narrowing the differential diagnostic considerations.
