ABSTRACT
Renal angiomyolipoma is known to affect mainly patients with tuberous sclerosis, although it can be found in a significant number of otherwise normal individuals. Few cases have been published in which angiomyolipoma and renal cell carcinoma occurred in the same kidney. In such cases the radiologist may be asked if it is possible to distinguish between the two tumors in the same kidney. The present case report describes systemic traditional and modern imaging of huge bilateral angiomyolipoma in tuberous sclerosis. The analysis of the data implies that, although the diagnosis of angiomyolipoma can be established with noninvasive techniques only, it is impossible to distinguish between the two mentioned tumors if they coexist in the same kidney, even if all available imaging techniques are used.

The first case of a common origin of both the inferior mesenteric and single main renal artery, angiographically documented in a patient with primary ipsilateral ectopic kidney, is reported. Embryologic as well as surgical aspects are mentioned.

In an effort to determine the frequency of extrahilar entry of the single main renal artery, renal angiographies of 124 left and 124 right kidneys were examined and the findings reviewed. Extrahilar entry of the main renal artery was found in 33 per cent of the kidneys. In 81.7 per cent of the kidneys with extrahilar entry, the artery penetrated the kidney through the upper zones (above the normal hilus). Apical entry of the renal artery was found in 1.6 per cent of the 248 kidneys. There was no entry of the single main renal artery below the hilus of the right kidney. An embryologic explanation of these findings is suggested, and some practical aspects are mentioned.

Two cases of extrahilar entry of a single main renal artery are described. Selective renal angiography demonstrated arterial entry through the upper pole of the kidney and venous exit, adjacent to the arterial entry. Embryologic as well as some surgical aspects are presented. To our knowledge only one similar variation of arterial supply to the kidney has been reported previously.

Two cases of intravascular leiomyomatosis are described. In 1 case, a 66-year-old woman was seen with an extension of the tumor to the myometrium, cervix, and left parametrium and with radiologic evidence of tumor extension to the left external and common iliac veins and the inferior vena cava; subsequently, the tumor invaded the left renal, suprarenal and ovarian veins, hepatic veins, and the right atrium, causing severe heart failure and death. The second case is that of a 28-year-old woman with an advanced tumor in the interior vena cava, right atrium, and ventricle who died during cardiac surgery. Review of the literature is presented, with special comment on the management of this disease entity.

Two cases with an unusually high origin of a single main left renal artery, angiographically investigated, are presented. In the first case the artery originates as the most cephalad branch of the abdominal aorta above the celiac artery. In the second case its origin is from the celiac axis. Embryologic as well as some practical aspects are mentioned.

The clinical, radiologic, angiographic, and operative findings in 15 patients with double aortic arch are described. In five patients, both arches were functional; in the other 10, a portion of the left arch was atretic. Depending on the location of the atretic segment, the anomalies were classified into types A, B, and C double aortic arch. We considered an additional type D double aortic arch which as yet remains a theoretical possibility. With the help of refined angiographic signs obtained by countercurrent right brachial angiography and on the basis of clinical and radiologic signs of tracheoesophageal compression, the differential diagnosis among various types of double aortic arch and right aortic arch anomalies was improved.

A 9-year-old girl with type D right aortic arch anomaly, has been presented. The diagnosis was based upon the presence of signs and symptoms of a vascular ring and the early visualization of a retroesophageal aberrant left innominate artery, by means of countercurrent right brachial angiography. Division of the ligamentum arteriosum at operation relieved the symptoms.

Four infants with type C double aortic arch (double aortic arch with aberrant left subclavian artery) are discussed. The diagnosis was based on symptoms and signs of tracheoesophageal compression with a bilateral impression in the frontal plane of the esophagogram, as well as on early visualization of the aberrant left subclavian artery during counter-current right brachial angiography. Division of the atretic segment of the left arch and of the ligamentum arteriosum relieved the symptoms.
