Renal failure due to bronchogenic adenocarcinoma metastatic to kidneys.

A case is presented of a fifty-eight-year-old woman with bronchogenic adenocarcinoma in whom renal failure developed manifested by hypertension and azotemia. Subsequent percutaneous needle aspiration biopsy confirmed metastatic renal involvement. No etiology other than renal infiltration due to metastatic bronchogenic adenocarcinoma was found to explain the renal failure. Literature review revealed no previous reported case of metastatic bronchogenic adenocarcinoma to the kidney presenting antemortem with renal failure.

Ectopic pregnancy: surgical-pathologic correlation with US.

The ultrasound (US) examinations of 53 patients with proved ectopic pregnancy were reviewed and compared with surgical and pathologic findings. The most common finding with US and surgery was free fluid. Hematosalpinx tended to have sharply defined margins, whereas free pelvic hematomas were poorly defined or filled the pelvis. The echogenicity of the clots was variable but generally in the same range of echogenicity as the uterus. A prominent decidual reaction occurred in 26% of the patients and had a variety of appearances.

Texture patterns in pancreatic sonograms.

In a retrospective study of 163 pancreatic sonograms, five internal echo patterns were correlated with the ultimate clinical diagnoses. Attention to the internal echo patterns of the pancreas can provide useful information in diagnosing pancreatic disease, including identification of abnormalities in glands of normal size and contour.

Circumscribed eosinophilic gastroenteritis.

A case of eosinophilic gastroenteritis with peripheral blood eosinophilia and typical histology is described. The location, radiographic appearance, and gross pathologic appearance of the lesion were unique in that they resembled eosinophilic granuloma of the stomach. Also unique was the fact that the distal esophagus as well as the stomach was involved. This case demonstrates that eosinophilic gastroenteritis may involve any portion of the gastrointestinal tract and that the radiologic distinction between eosinophilic gastroenteritis and eosinophilic granuloma may not be as clear cut as previously thought.

Accuracy of placental localization by ultrasound.

In a retrospective study, ultrasound diagnoses were correct in 93% of 164 patients referred for examination because of suspected placenta praevia. There was one false-negative finding in 13 cases of proven placenta praevia, and ten false-positive errors in 151 true-negative cases. False-positive results represented the largest number of errors. Examination of the patient with an empty bladder, in addition to the routine technique, is suggested to reduce the number of false-positive results.

Ultrasound in the staging of lymphoma.

Ultrasonography of the abdomen and pelvis was performed in 16 patients with lymphoma who underwent clinical and pathologic staging. The results of the ultrasound examinations were correlated with the pathological findings as were the results of gallium-67 scans, inferior vena cavagrams and lymphangiograms obtained in the same group. Analysis of the data indicated accuracies in the 80-90% range and specificities of greater than 90% for ultrasound. The sensitivity of ultrasound was somewhat lower, in the 60-70% range. These findings compare favorably with those of the other diagnostic procedures evaluated and indicate the usefulness of ultrasound in the staging of lymphoma.
