RESUMO
We describe the ultrasound (US) appearance of transient synovitis. Transient synovitis of the hip typically occurs in 3 to 8-year-old children. The onset is clinically characterized by acute hip pain and limp with limited joint mobility, and the leg is usually held in a position of flexion and external rotation to avoid pain. US image is characterized by joint effusion in the hip joint anterior recess, as described in the literature. Our experience confirms the importance of the technique with which the US examination is performed. In order to obtain the best diagnostic information the hip must be examined with the patient in the supine position and the hip joint in a neutral position (abduction of the hip with extension and slight external rotation) by means of an anterior approach along the long axis of the femoral neck in the parasagittal plane.
RESUMO
INTRODUCTION: Varicoceles are abnormal dilatations of the pampiniform venous plexus. They are classified as primary or secondary, depending on their cause, and staged clinically on the basis of their extension and on the presence or the absence of spontaneous or induced reversal of blood flow. MATERIALS AND METHODS: We examined 95 patients (age range: 3-77 years) using Color Doppler ultrasound with settings optimized for the study of slow flow. All patients found to have varicoceles underwent ultrasonographic assessment of the kidneys and retroperitoneum. Findings were classified with a simplified version of the Sarteschi system. RESULTS: 41 (43.1%) of the patients were found to have varicoceles, which were classified as grade 1 in 11 cases, grade 2 in 13, grade 3 in 10, and grade 4 in 7 according to the simplified Sarteschi classification. DISCUSSION: Our results are with those reported in the literature. They confirm that varicoceles are a frequent finding and ultrasonography is currently the best imaging technique for its diagnosis and also for the post-surgery follow-up.
