Abstract :

Septic arthritis which is infection of various types of joints due to introduction of pathological organisms in joint space have many adverse outcomes. If not recognized and treated on time, irreversible joint damage and permanent disability can occur. Earliest radiographic changes are seen 7 to 10 days after onset of infection, however MRI changes can be detected within 3–5 days. We have attempted to characterize various MRI features in our study. Pulse sequences included coronal T1–weighted (early and late after contrast administration), coronal T2–weighted, and coronal STIR, sagittal T1–weighted, sagittal T2–weighted. Images were retrospectively reviewed for location of the joint involved, presence of joint effusion, synovial thickening, peri–synovial edematous changes and synovial enhancement. Presence of the bone marrow involvement and extent was evaluated by abnormal signal on T1–weighted images, T2–weighted images, STIR and contrast–enhanced images. Bone destruction was also evaluated using the images. Periarticular involvement in form of peri–synovial odematous changes, muscle and fascial plane involvement and collection were noted. The most commonly involved joints were small joints of foot (n =15). Most commonly isolated organism was staphylococcus aureus (60%, n = 18). The bone destruction was noted 10 patients. The periarticular involvement showed perisynovial odema in 26 cases (87%), Muscle and fascial involvement in 14 cases (46%) and well defined collection in 10 cases (33%). Bone involvement showed Abnormal T1W signal in 21 cases (80%), Abnormal T2W signal in 27 cases (90%), Abnormal T1W and T2W signal in 21 cases (80%) and Post contrast enhancement in 25 cases (83%).
