Angiographic Features of Cavernous Hemangioma of Liver

Lobectomy of the liver is no longer an uncommon surgical procedure. Because of increasing surgical skill and the technic of selective chemotherapeutic perfusion of the liver, accurate pathologic diagnosis is vital. Several reports show long-term survival after resection of the liver for hepatocellular carcinoma (3, 6, 8, 10, 13). The angiographic findings of cavernous hemangioma, a benign disease, have at times been confused with those of hepatic-cell carcinoma. It is our purpose to show that angiographic differential diagnosis is feasible. Cavernous hemangioma of the liver, while rare, is one of the most common benign tumors of the liver. It is most often first detected at necropsy. The female predominance is high, with figures ranging from 70 to 95 per cent. It occurs more frequently in older multiparas, usually those with four or more pregnancies. The occurrence of this tumor in animals, particularly in older cows, and its reported rapid enlargement during pregnancy may suggest a hormonal relationship....

Ultrasonic Diagnosis of Pericardial Effusion

This study was undertaken to establish a method for diagnosing pericardial effusions quickly, simply, and accurately without danger to the patient. Ultrasound examination that was used in this study employed the B mode (cross-sectional representation) in which the vertical deflections of the A scan are turned on end and make a line of dots on the cathode ray tube. These, at the appropriate time, outline the anatomy including moving structures which are seen as wavy lines in the final picture and on the fluorescent oscilloscopic screen. Forty-three patients, 23 suspected of having pericardial effusion, were studied. The diagnosis usually was made on posterior examination and confirmed on anterior examination. Cardio-echograms are shown to provide an accurate, quick, simple method of diagnosing pericardial effusion that is accurate for use in estimating the size of the large effusions.

The spectrum of roentgen appearance in amyloidosis of the small and large bowel: radiologic-pathologic correlation.

Abstract The roentgen findings in 13 cases of small and large bowel amyloidosis were correlated with the pathologic findings. The degree of amyloid deposition within the blood vessels, mucosa, and muscular layers of the bowel wall was estimated on a + to ++++ scale. A good correlation was obtained between the degree of amyloid deposition and the roentgen appearance, which ranged from normal to thickened or effaced valvulae conniventes and haustral folds to ulcerations secondary to ischemia. Vascular amyloid deposition is important in the production of morphologic alterations seen on x-ray examination.

Angiographic features of hamartoma of the kidney. A case report.

Hamartoma of the kidney is a rare benign tumor in the absence of tuberous sclerosis. It may be bilateral (1, 5). Often it is a combination of more than one connective tissue element, with either the fatty, fibrous, muscular, or vascular element predominating. Conventional methods of investigation are effective when the fatty tissue is dominant in the neoplasm (1). To date, 7 cases have been reported after aortography (2–4, 6, 7). In the case which follows, renal angiography illustrated some distinctive arteriographic changes that were also noted by Viamonte (8). A 29-year-old female was admitted with a 3-week history of left flank pain and a palpable left kidney mass. The findings of the laboratory examinations were normal. An intravenous pyelogram showed a mass in the superior pole of the left kidney, displacing the collecting system (Fig. 1). A nephrotomogram demonstrated the lesion to be ill-defined superiorly; inferiorly, however, it was sharply delineated from adjacent normal kidney structure. The ma...

Angiographic Studies of Benign and Malignant Cystadenoma of the Pancreas

Benign and malignant cystadenomas of the pancreas are very rare lesions (1, 7, 8), only about 75 cases having been reported in the worlds literature (7, 13). Lichtenstein in 1934 reported the first authenticated case of a malignant cystadenoma of the pancreas in America (6). Various workers have reviewed the literature and added one or two personal cases. P. Kent Cullen, Jr., et al. reviewed the literature to 1963 and collected 86 cases, 42 of which were malignant (4). Their analysis of almost 2.5 million admissions at the Mayo Clinic disclosed that a very small fraction of one per cent showed either benign or malignant cystadenoma of the pancreas. Thus, few cases are available for study at anyone institution. It has been our privilege to have studied four such cases angiographically and to have correlated our findings with surgical and/or autopsy material. Three cases were benign and one malignant. Clinical Findings Females predominate in a ratio of approximately 8: 1 (2–4). The lesions may be encounter...

Renal and Suprarenal Pseudotumors Caused by Variations of the Spleen

Abstract Variations in the contour and position of the spleen simulated renal or suprarenal masses on routine radiographic studies in 5 patients. Angiography was able to determine the true etiology of the apparent masses in 4 (assisted by isotopes in one case). Localized flattening of the upper pole of the kidney, usually thought to indicate adrenal disease, was seen in 3. Splenic variations included a lumpy spleen, a transverse spleen with a prominent superior pole, a rotated and ptotic spleen, a depressed spleen, and an accessory spleen.

Computed tomography of the diaphragm: Normal anatomy and variants

Computed tomographic examinations in 75 normal individuals are analyzed to define the cross-sectional anatomy of the diaphragm. Anatomic relationships among the inferoposterior portions of the lungs, the pleura, and the hemidiaphragms are clarified. The posterior pleural recess, an important potential space, is described and illustrated. The relationships of the crura, arcuate ligaments, and the hemidiaphragms are discussed as well. Awareness of these anatomic relationships forms an important basis in analyzing peridiaphragmatic fluid collections.

Aneurysm of the gastro-duodenal artery

Aneurysms of the hepatic artery and its branches are rare. One hundred and seventy cases of hepatic artery aneurysm were reviewed by Guida and Moore (1966). Blair and Yeager (1966) cited five cases of an aneurysm of the superior pancreatico-duodenal artery and gave a detailed account of one case of their own. The purpose ot this presentation is to report one case of an aneurysm of the gastro-duodenal artery which has thus far not been previously reported in the literature.

Small polypoid lesions associated with spastic diverticulosis

ConclusionsSpastic diverticulosis is defined and differentiated from diverticulitis. Persistence of the filling defect and constancy of its location are not essential for the diagnosis of a small polypoid lesion in an area of spastic diverticulosis.A single positive finding of an intraluminal defect in spastic diverticulosis is more significant than numerous negative findings. Discovery of an intraluminal defect in an area of spastic diverticulosis demands re-examination after antispasmodic therapy.Differentiation between a polypoid lesion in an area of diverticulosis and the intrinsic features of diverticulitis are discussed. Circumferential visualization of the colon is essential to differentiate a polyp from a diverticulum. Fecal defects in an area of spastic diverticulosis are comparatively uncommon, so that such a defect should be considered a polypoid lesion until its presence is disproved.

Congenital Absence of the Anterior Tibial Artery

Much of the material presented in the American radiological literature on the arteriography of the lower extremity is concerned with occlusive disease, collateral pathways, aneurysms, vascular malformations, tumor circulation, and technical data. Little has been written on congenital variations and anomalous arterial supply. Two case reports concerning persistence of the primitive sciatic artery appeared in the British literature in 1964. 1. :! Lindbom, in the Scandinavian literature,3 describes situations in which there is only one posterior tibial artery, hypoplasia of the anterior tibial artery, and hypoplasia of the posterior tibial artery. Complete absence of the anterior tibial artery is not described. Gray’s Anatomy does comment that the anterior tibial artery may be completely absent. The embryological basis for this and other anomalies can be derived best from Arey’s text.&dquo; The popular American texts which deal with arteriography do not discuss the vascular anomalies in any great detail, although .Tacobson and Shapiro6 do point out that the popliteal artery may form B
