The abdomen has been conveniently divided anatomically and clinically into specific intraperitoneal and extraperitoneal sites. A recognition of the pathways of spread and localizing features of infections, malignancies, and traumatic collections has immeasurably extended diagnostic imaging capabilities. Yet, while the abdomen may be visualized as subdivided(More)
Large, infiltrative cavernous hemangiomas of the distal colon were present in 3 children with the Klippel-Trenaunay syndrome, 2 of whom are the subject of this report. The lesion is manifested clinically as intermittent rectal bleeding starting in the first 5 years of life. The radiographic features include (a) varicose lesions in the wall of the(More)
The cause of bleeding was found in 8 of 10 cases of colonic diverticulosis associated with severe rectal hemorrhage by using arteriographic and microangiographic techniques to localize the site and serial histological sections to study the lesion. Strikingly consistent changes were identified. These are related to the characteristic angioarchitecture of(More)
The chronic encapsulated extravasation of urine, most accurately designated as uriniferous perirenal pseudocyst, causes urine to collect within a characteristic complex of radiographic findings including an elliptical soft-tissue mass in the cone of renal fascia. This results in the flank oriented inferomedially with upward and lateral displacement of the(More)
Fiberoptic colonoscopy is being used increasingly for endoscopic visualization of the large intestine, particularly in the electrocautery removal of polypoid lesions. Complications may include bleeding, mesosigmoid hematoma, splenic avulsion, and impaction of the instrument, but the most common is perforation of the colon, which occurs in 0.4-1.9% of(More)
