Jugular venous ectasia in children. A report of 3 cases and review of the literature.

Three cases of jugular venous ectasia in children were diagnosed preoperatively by selective venography. These rare lesions appear to be congenital dilatations of the veins and should not properly be called aneurysms, as their histological structure is normal. A typical history and complex of physical findings are associated with this entity. It is important to include it in the differential diagnosis of neck masses in children.

Arteriography of peripheral hemangiomas.

Arteriography has proved useful in evaluation of 17 patients with peripheral soft-tissue hemangiomas (15 benign, 2 malignant) by defining their extent, degree of vascularity, and source of vascular supply and allowing differentiation from arteriovenous malformations. In 11 cases (all benign), moderate fine-caliber hypervascularity with some degree of staining was seen. In 6 (4 benign, 2 malignant) there was marked hypervascularity with coarse, irregular vessels. The coarse or fine hypervascularity which characterizes most benign hemangiomas closely resembles that seen in malignant soft-tissue tumors and may preclude correct diagnosis by angiography alone. However, peripheral hemangiomas frequently exhibit distinctive clinical features which when combined with the arteriographic findings enable the radiologist to identify the lesion.

Arteriography of retroperitoneal lymphoma.

Arteriography was performed in 16 patients with various types of lymphoma involving the retroperitoneal space. The location and extent of the mass could be predicted in 15 cases, based upon displacement of major arteris or kidneys. Most of the studies demonstrated some degree of fine reticular neovascularity and staining within the mass; none showed extreme hypervascularity, coarse or ragged vessels, or pooling of contrast medium during the capillary phase. The differential diagnosis of lesions with this appearance includes metastases, sarcomas, neural tumors, and inflammatory masses. Arteriography may possibly prove to be of value in staging certain patients with lymphoma, although definitive assessment of its role must await further prospective studies.

Further observations on pulmonary venous varix.

Pulmonary venous varix is a well known radiographic entity. Case reports are presented to illustrate the following unusual aspects of this lesion. 1. Hypoplasia of a major pulmonary vein results in increased pulmonary blood flow through the remaining normal ipsilateral pulmonary vein. This may result in variceal enlargement of the normal vein. 2. A pulmonary venous varix may be visualized during angiocardiography but not in a routine chest radiograph. This is most common in children. 3. Elevated pulmonary venous pressure causes dilatation of the central pulmonary veins. Sudden formation of a pulmonary venous varix in a patient with mitral valvular disease may be evidence of a sudden elevation of left atrial pressure.

"Rectal ears".

"Rectal ears," transitory protrusions of the rectum into the internal inguinal rings, were observed in a 16-month-old girl who also had "bladder ears." Inguinal hernias were not present. The etiology and significance of "rectal ears" has not been determined.

Abdominal computed tomography in lupus mesenteric arteritis.

We report the abdominal computed tomography (CT) findings in a patient with systemic lupus erythematosus who developed signs of an acute abdomen secondary to mesenteric arteritis. Initial CT scan demonstrated ascites and wall thickening of the duodenum and jejunum. After treatment with high dose intravenous steroids, follow-up CT scan demonstrated a normal duodenum and small bowel. This is the first surgically proven case of lupus mesenteric arteritis resulting in bowel ischemia that is demonstrated on CT before and after medical therapy. Lupus mesenteric arteritis should be included in the differential diagnosis of causes of bowel wall thickening and ischemia, especially if mesenteric vessels appear prominent.

Pitfalls in diagnosis of aortic dissection by angiography: algorithmic approach utilizing CT and MRI.

Dissection of the thoracic aorta is a life-threatening event requiring imaging studies to define the level of the tear and the intimal flap. The "gold standard" has been angiography. This method may fail to demonstrate the dissection, however, due to overlap of the true and false lumens or a very thin flap that is imaged en face rather than tangentially. Computed tomography has a diagnostic accuracy of 95%, but can fail to image the dissection due to technical factors or a thrombosed false lumen. Magnetic resonance imaging requires a hemodynamically stable and cooperative patient. A diagnostic algorithm is proposed for diagnosis of aortic dissection based on renal function and the surgeon's imaging modality preference.

Sarcoidosis of the liver: evaluation with multiple imaging modalities.

Although sarcoidosis of the liver is common pathologically, imaging findings are extremely rare, because the noncaseating granulomas are usually not macroscopic and thus do not produce focal abnormalities. We present 2 cases of liver sarcoidosis with focal findings on computed tomography, magnetic resonance imaging, nuclear scanning, and ultrasonography. Imaging characteristics, which may facilitate making the diagnosis, are presented.

Malrotation of the bowel: malalignment of the superior mesenteric artery-vein complex shown by CT and MR.

A malposition of the superior mesenteric vein on cross-sectional imaging was seen in four adult patients with malrotation of the bowel and is diagnostic of this entity. This sign should be looked for on CT or magnetic resonance to explain ill defined symptomatology and to define who may be at risk for future complications. We also define a "pseudo-superior mesenteric artery-vein sign" due to mass displacement of the pancreas, which must be distinguished from true malrotation.
