ABSTRACT
Intraplaque hemorrhage is one of the complications of atherosclerotic plaques. It causes clinical manifestations of ischemia without hemodynamically significant stenosis. MRI has a high capacity for the study of the tissular components of atheromatous plaques and is an efficacious diagnostic method in cases of intraplaque hemorrhage. Symptomatic patients with unstable (complicated) plaques, regardless of the degree of stenosis present, might benefit from surgical treatment (endarterectomy). In these cases, the diagnostic value of a noninvasive technique like MRI is fundamental. We present three cases of intraplaque hemorrhage with clinical manifestations of ischemia studied with MRI.

La hemorragia intraplaca es una de las complicaciones de las placas de ateroma, y provoca manifestaciones clínicas de isquemia sin estenosis hemodinámicamente significativa. La resonancia magnética (RM) posee alta capacidad de estudio de los componentes tisulares de la placa de ateroma, siendo un método de diagnóstico eficaz en los casos de hemorragia intraplaca. Los pacientes sintomáticos con placas inestables (complicadas), y con independencia del grado de estenosis, podrían beneficiarse del tratamiento quirúrgico (endarterectomía). En estos casos el valor diagnóstico de una técnica no invasiva como la RM es fundamental. Presentamos 3 casos de hemorragia intraplaca con manifestaciones clínicas de isquemia, estudiados con RM

We describe a case of pyomyositis of the quadriceps associated with septic arthritis of the knee that developed after Fusobacterium nucleatum septicemia in a healthy man. The primary foci was presumed to be the oral cavity. Pyomyositis from Fusobacterium nucleatum is uncommon, and to our knowledge its association with septic arthritis has not been described.

The clinical and radiological features of 15 cases of fascioliasis are reported. Pleural effusion, associated with pulmonary infiltrates or ascites, was observed in two patients. Computed tomography (CT) was the most useful imaging method, showing small nodules and linear tracks within the liver parenchyma which were hypodense on non-enhanced scans, remaining hypodense or becoming isodense with normal liver after contrast medium administration. After successful treatment lesions decreased in number and size and finally disappeared or calcified. Lesions increased or remained unchanged when treatment failed to control the disease.
