Genitourinary imaging techniques.

In the current era of pediatric uroradiology, use of nuclear medicine, ultrasonography, CT, and MRI has been valuable in the identification and management of genitourinary diseases. Excellent information about the renal parenchyma and renal function is currently attainable with current cross-sectional imaging techniques that can identify tissue differentiation of lesions, distinguish dilatation of the pelvocalyceal system, and determine margins of the kidney and perirenal space. Invasive angiography is limited in application specifically to vascular diseases, although they are uncommon in childhood.

Increased diagnosis of Lemierre syndrome and other Fusobacterium necrophorum infections at a Children's Hospital.

Objective: To assess the apparent increase in the diagnosis of Lemierre syndrome (LS) and other Fusobacterium necrophorum infections at a large children's hospital. Infections with F necrophorum ranged from peritonsillar abscess to potentially fatal LS. LS is an oropharyngeal infection characterized by septic thrombophlebitis of head and neck veins, complicated by dissemination of septic emboli to pulmonary and systemic sites.
