Uterine adnexal torsion: sonographic findings.

Acute torsion of the uterine adnexal structures (ovary and fallopian tube) is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. This report describes 16 cases in which the diagnosis was suggested preoperatively on the basis of sonography and subsequently confirmed at surgery. In all of the patients studied, a pelvic or pelvoabdominal mass was present on sonography. These masses had a sonographic texture ranging from cystic to solid, depending on the presence and extent of internal hemorrhage and/or stromal edema. In the majority of patients (13 of 16), adnexal torsion was associated with a preexisting cystic adnexal mass. Eight of these had thin internal septae. The severity of symptoms was variable and did not correlate directly with the sonographic features of the pelvic mass. Consideration of this entity in the proper clinical setting and with the typical sonographic findings will facilitate prospective recognition of adnexal torsion, thereby improving the chances for salvage of the involved adnexal structures.

The sonographic appearance of acute pyelonephritis.

Acute pyelonephritis and acute ureteral obstruction often present with similar clinical and urographic findings. Ultrasound, however, can easily detect the presence of obstruction as well as demonstrate characteristic findings suggestive of acute pyelonephritis, and thus allows differentiation. In two patients with acute pyelonephritis, the ultrasonic findings consisted of a large swollen kidney with an increased anechoic corticomedullary area, with multiple scattered low-level echoes. Each of the two cases is discussed in detail.

Ultrasonic differentiation of types of ascitic fluid.

A review of 65 cases of proven ascites was done to assess the accuracy of ultrasound in distinguishing transudates from exudates. In 10 patients with malignant ascites, ultrasound suggested this in six by showing matted bowel loops, loculation, or hepatic metastasis. In each of the five patients with peritonitis, infected ascites was suggested by observing septations or debris within the fluid. A sonographic diagnosis of exudate was not made in any of the 50 confirmed transudates. The echographic characteristics which may suggest infected or malignant ascites are discussed.

Mediastinal pancreatic pseudocyst. An ultrasonic diagnosis.

Mediastinal extension of pancreatic pseudocysts is uncommon. Frequent presenting complaints include chest pain and shortness of breath. Dysphagia is rare. A patient with mediastinal pseudocyst causing dysphagia is presented. The role of gray-scale ultrasound as a reliable means of diagnosis is discussed.

Ultrasonic properties of gallstones. Effect of stone size and composition.

In vivo and in vitro ultrasonic characteristics of gallstones were compared with stone size and composition with the aim of understanding the basis for these features. In vivo and in vitro ultrasonic features of the same stone were identical. Acoustic shadowing was not due to stone type, radiodensity, or calcium content. However, all stones larger than 4 mm in diameter produced a distinct sonic shadow. Gallbladder sludge produced internal echoes without a sonic shadow. These echoes shifted slowly when the patient was reexamined in a different position. Four of seven cholesterol stones containing more than 88% cholesterol floated and produced a sonic shadow without internal echoes or with an area of internal echoes within the gallbladder at a distance from the posterior wall. This last feature may identify patients that are good candidates for a trial of gallstone dissolution with chenodeoxycholic acid.

Pleural effusion aspiration with ultrasound.

This paper describes how pulsed ultrasound applied through a combined transducer-aspirator aids in the location and complete aspiration of pleural exudates, particularly loculated ones, which may be difficult to assess fully using clinical techniques alone.

Determination of bladder volumes by gray scale ultrasonography.

Gray scale ultrasonography was used to measure bladder volumes. A high degree of accuracy (r = 0.097) in correlating volumes with instilled volumes is attributed to the inherently greater accuracy of gray scale as compared to bistable B-mode scanning.

Transverse folds in the human esophagus.

Fine transverse folds can be seen by double contrast technique in the human esophagus which are similar to those seen regularly in the feline esophagus. These folds are transient in nature and possibly represent contraction of the muscularis mucosae. This fold pattern can be seen in patients with gastroesophageal reflux and in those with no symptoms of esophageal disease. The marginal serration should not be mistaken for diffuse ulceration on barium filled views of the esophagus. Distortion of interruption of the normal fold pattern can be seen in patients with superficial ulceration due to reflux esophagitis or other invasive mucosal lesions. Although the pathophysiologic significance of this phenomenon is uncertain, the demonstration and recognition of these folds allows for better definition of mucosal surface abnormalities.
