MR imaging is the ideal technique to display the soft-tissue abnormalities produced by infectious processes. In general these soft-tissue alterations consist of signal intensity changes that reflect the increased water content of the soft tissues induced by the inflammatory reactions. In some cases these changes are nonspecific, but in others, MR imaging can be quite specific and helpful in detecting the presence and extent of the infection, which generally is suspected clinically on the basis of physical and laboratory findings. The MR manifestations of soft-tissue infection, including septic arthritis, tenosynovitis, bursitis, cellulitis, necrotizing fascitis, soft-tissue abscess, infectious myositis, HIV-related infection, lymphadenitis and lymphangitis, and a few unusual parasitic and fungal infections, are reviewed.

Deep venous thrombosis (DVT) is a major health problem and is estimated to have an incidence of 600,000 cases per year. Clinical signs and symptoms of DVT are unreliable. If clinical signs alone were used to diagnose DVT, 42% of patients would receive unnecessary anticoagulation therapy. Most patients evaluated with ultrasonography (US) do not have DVT. The key to making a precise diagnosis is recognizing the characteristics of various diseases on US images. The anatomic approach is the most useful strategy for characterizing the spectrum of pathologic conditions seen in patients with symptoms that simulate DVT. The inferior extremity can be divided into four regions-inguinal, thigh, popliteal, and lower leg-with the rough limits defined for each as they are examined at US. The differential diagnoses affecting the lower extremities include infectious, neoplastic, traumatic, inflammatory, vascular, and miscellaneous entities. Some pathologic conditions seen in the inguinal region are adenopathies, lymphangitis, soft-tissue tumors, hematomas, adductor tendonitis, and hernias. In the thigh, cellulitis, myositis, abscess, benign and malignant tumors, and sports-related lesions are seen. In the popliteal region, cellulitis, arthritis, benign and malignant masses, muscle contusions, ruptured popliteal cysts, and thrombophlebitis are seen. And in the lower leg, cellulitis, lipomas, tennis leg, superficial thrombophlebitis, tendonitis, and soft-tissue hydrostatic edema secondary to cardiac and renal failure can simulate DVT.
