A spectrum of rare urachal abnormalities in the adult is described, including urachal cyst, infected urachal cyst and abscess, and urachal carcinoma. The clinical and radiographic features are presented, and diagnosis using ultrasound, computed tomography, and needle aspiration is discussed. Treatment of infected urachal cysts with percutaneous catheter(More)
A case of a rare acquired form of aqueductal stenosis and hydrocephalus developing as a late sequela of mumps virus infection of the central nervous system is presented. The experimental studies of mumps induced aqueductal stenosis in hamsters and mice and the four previously reported cases in the literature are reviewed.
Growing concern about acute renal failure as the result of contrast agents prompted an investigation into the renal effects of intravenous contrast materials in euvolemic and dehydrated dogs. Bolus injection of hypertonic agents induced marked reductions in filtration fraction and glomerular filtration rate in both groups of animals; however, these changes(More)
Investigations into the nature of severe and fatal reactions to contrast media have been severely limited by their unpredictable occurrence in the clinical setting and the absence of suitable laboratory models. The authors report their experience with a canine dehydration model. Intravenous administration of 2 ml/kg of 76% sodium methylglucamine diatrizoate(More)
Thirty-two cases of proved pineal tumor were analyzed. Calcification was seen in 75%. The size, character, and position of the calcification were useful indicators of abnormality on plain-film evaluation. Fray's cranioangle method was more sensitive than Oon's method in determining abnormal position of the calcified pineal tumor on the lateral skull film.(More)
Herein we review 100 cases of adult polycystic kidney disease. Flank pain was the most common presentation in these cases. In 20% of the patients calculi were noted and 10% had obstruction. The average patient age at death was 57 years. The importance of tomography is emphasized with key radiographic features, such as bilateral large kidneys, inhomogeneous(More)
Twenty-three cases of polycystic disease were reviewed. All were easily detected by computed tomography. All manifested diffuse, bilateral renal cystic disease, and 74% had demonstrable hepatic cystic disease. Computed tomography is more accurate than other conventional modalities in diagnosing renal cysts, and its simplicity of operation and ease of(More)
