Three other types of duodenal polyps: mucosal cysts, focal foveolar hyperplasia, and hyperplastic polyp originating from islands of gastric mucosa.

Seven cases are reported that initially presented on endoscopic examination as duodenal polyps originating from islands of gastric mucosa within the duodenal bulb. Microscopic examination revealed mucosal cysts (MC), focal foveolar hyperplasia (FFH), and hyperplastic polyp (HPP). These lesions must be added to the list of neoplastic and tumorlike lesions of the duodenum that may endoscopically present as polyps.

[Sonographic determination of spleen size: normal dimensions in adults with a healthy spleen].

Sonography can rapidly and reliably help to determine the size by the spleen. To standardise the sonographic dimensions of the healthy spleen, we effected sonographic examination of 793 female and male patients aged between 17 and 82 years with a healthy spleen. In 95% of the patients the length of the spleen was less than 11 cm, the breadth below 7 cm and the thickness less than 5 cm. The weight of the spleen as determined via the rotation ellipsoid formula was below 190 g in 95% of the patients. Whether or not a spleen larger than standard signals an acute disease can be clinically assessed only on the basis of a synopsis of all findings.

[Qualification and quality control in sonography].

On the basis of guidelines issued by the Kassenärztliche Vereingung Hessen, some criteria for the application of sonographic examinations are presented. Minimal requirements for sonographic equipment in certain specialties are mentioned, and it is pointed out how not only case history and clinical examination but also one's own sonographic evidence are important for a accurate sonographic diagnosis.

A pseudolesion of the liver caused by rib cartilage in B-mode ultrasonography.

An artifactual protuberance at the surface of the liver in connection with an incomplete acoustic shadow is described. The reproduction of these phenomena in vitro was possible, providing an explanation of their origin. Rib cartilage, with its convex shape, and with the higher sound wave velocity and the higher attenuation compared with the surrounding tissue, causes these artifacts. The identification of a pseudolesion composed of these artifacts is simple if one considers its origin.

[Sonography and pharmacoangiography of the pancreas (author's transl)].

Real-Time-Sonography and pharmacoangiography with vasodilating drugs was performed in 63 patients with suspected pancreatic disease. Confirmation of the pancreatic lesion could be obtained in 41 cases by the symptomatology, pancreatic function test, autopsy, operation, laparoscopy with fine-needle-biopsy and by the roentgenologic visualization of pancreatic calcifications. Considering the relatively advanced disease of pancreatic carcinoma in our six patients the sonographic diagnosis was correct in all of them and with pharmacoangiography we failed on one case. In chronic pancreatitis correct diagnostic results with pharmacoangiography could be obtained in 8 of 18 cases and with sonography in 14 of 18 patients. In this study sonography showed certain advantages in comparison with angiography, but both methods were complementary and a better result in the differential diagnosis between chronic pancreatitis and pancreatic carcinoma could be achieved.
