ABSTRACT
The ultrasonic demonstration of compression of the anterior (ventral) wall of the inferior vena cava by the pancreatic head was proved to be a reliable sign of neoplasm enlarging the pancreatic head in 10 patients. It would appear that this sign is less reliable and probably not as important diagnostically in patients with pancreatic head enlargement secondary to pancreatitis or pseudocyst. This sign must be constant and reproducible on longitudinal scans done with a single transducer pass in suspended inspiration. This sign was not seen in 50 patients who had no evidence of pancreatic disease.

A patient is presented who had a hydatidiform mole with a coexisten fetus and bilateral theca lutein cysts. The complete diagnosis was made by grey-scale ultrasonography.

The authors describe the ultrasound appearance of cystadenoma of the pancreas. Such lesions may be characterized as sonolucent, with good through-transmission, slightly irregular but well-defined margins, and internal echoes from septa.

The results of ultrasonic B-scanning of 11 patients with malignant neoplasms of the stomach are presented, and the diagnostic accuracy of this technique and its advantages and limitations are discussed and illustrated with specific case reports. The use of ultrasound to complement other techniques in evaluating malignant gastric neoplasms prior to consideration for surgery or chemotherapy is outlined.

Three cases of anencephaly diagnosed in utero by ultrasound are presented and the ultrasound diagnostic criteria for anencephaly are illustrated. The literature regarding anencephaly is reviewed and the malformation discussed. Diagnostic ultrasound should be used to screen high-risk patients for this fetal anomaly. In addition, all patients clinically suspected of possible fetal malformation or polyhydramnios should be examined by ultrasound.

In this study 217 patients with proved abdominal aortic aneurysm were reviewed and the diagnostic accuracy of ultrasonography was assessed in comparison with physical examination, plain abdominal roentgenography, and aortography for the evaluation of patients with a suspected abdominal aortic aneurysm. Ultrasonography is most accurate in detecting an aneurysm and in defining the size of the aneurysm. Routine aortography to evaluate the renal and iliac artery is not justified in the preoperative evaluation of patients with an abdominal aneurysm since the renal artery infrequently is involved by the aneurysmal process (3.7 percent) and the surgical results are consistently successful in those patients with renal and/or iliac artery involvement. If preoperatively needed, the renal status can be evaluated accurately with an isotope renogram combined with photoscan of the kidney. A practical approach to the diagnosis of pulsatile abdominal masses is proposed.

Seminal vesicle cysts are uncommon, particularly when associated with ipsilateral agenesis of the kidney, ureter, and/or trigone. This entity should be considered when a cystic pelvic mass is seen in a young male. B-scan ultrasound can be of considerable aid in making the diagnosis.

Over 200 patients were examined by B-scan ultrasound for suspected pancreatic disease; in 94 cases a final diagnosis was proved. The diagnostic accuracy of ultrasound, upper gastrointestinal examination, isotope pancreatography, and arteriography is compared. The diagnostic ultrasound features of the various pancreatic disease processes are described. Pancreatic sonography provides the most accurate and least expensive method for evaluating the pancreas with no known patient morbidity. The upper gastrointestinal series and radionuclide study are complementary to sonography. Ultrasound should be the initial examination for the evaluation of patients with suspected pancreatic disease or epigastric mass.
