Characteristics of calcification in tumors of the pineal gland.

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. Most calcifications were displaced postero-inferiorly or inferiorly, which can be explained by obstructive hydrocephalus or direct tumor expansion.

Diagnosis of nonopaque calculi by computed tomography.

Computed tomography can aid in the distinction of calculi from both tumors and clots in the urinary tract. Its availability, simplicity of interpretation, and noninvasiveness establish it as an important diagnostic modality in selected cases when calculus is in the differential diagnosis of upper urinary tract filling defects.

The use of percutaneous nephrostomy and urinary alkalinization in the dissolution of obstructing uric acid stones.

Two patients are described who presented with complete urinary obstruction secondary to nonopaque uric acid stones. They were treated with percutaneous nephrostomy for urinary diversion and urinary alkalinization by local irrigation and oral sodium bicarbonate therapy with complete dissolution of the stone after 16 and 21 days of therapy. Percutaneous nephrostomy with urinary alkalinization is a reasonable, relatively safe alternative to surgical stone removal for patients with obstructing uric acid stones.

Adult polycystic kidney disease: a review of 100 cases.

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 nephrogram, caliceal distortion and poorly defined renal margins. Cystic involvement of the liver and spleen may help to confirm the diagnosis. Differential diagnosis includes bilateral multiple simple cysts, angiomyolipomatosis and bilateral renal carcinomas.

Urinary tract obstruction in polycystic renal disease.

The incidence and cause of urinary tract obstruction in 100 consecutive patients with polycystic renal disease are reported. Because of nonspecific symptoms, poor renal function, and calyceal distortion, obstruction may be difficult to detect. A number of patients had infundibular obstruction caused by a calculus, clot, or inflammation and edema of the pelvocalyceal wall.

Aqueductal stenosis and hydrocephalus: rare sequelae of mumps virus infections.

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.

Epinephrine enhanced knee arthrography.

The effect of .3 cc of 1:1000 epinephrine on iodine concentration, total iodine content, fluid volume and radiographic quality was evaluated in knee arthrograms in dogs. With the addition of epinephrine the iodine concentration and total iodine content were significantly higher initially and remained significantly higher than in controls over a one hour period. The fluid volume in the knee was significantly lower with epinephrine. Initially both contrast absorption and dilution have major effects in decreasing iodine concentration. With increasing time the effect of contrast absorption becomes the major factor, having a two of three times greater effect on decreasing iodine concentration. With epinephrine radiographs were judged significantly better early and while the quality deteriorated rapidly in the controls the enhanced quality with epinephrine persisted up to one hour. Epinephrine is a very useful adjunct in enhancing the quality of knee arthrography.

Clinical comparison of Hexabrix, iopamidol, and Urografin-60 in whole body computed tomography.

Urografin 60, iopamidol and Hexabrix were studied in patients undergoing body CT scans to examine the pharmacodynamics of these contrast agents. Immediately following rapid injection, the lower osmolality media, Hexabrix and iopamidol, gave greater aortic concentration of iodine in addition to higher concentrations in the liver and spleen. These two agents also provided significantly better renal enhancement than Urografin 60, with Hexabrix giving higher levels than iopamidol. The higher early vascular concentrations of Hexabrix and iopamidol and the relative absence of side effects due to hyperosmolality and decreased toxicity may have advantages in dynamic CT scanning.
