A patient with pseudomembranous colitis is described in whom a percutaneous cecostomy was performed using computed tomographic guidance. Several lines of evidence indicate the safety of this approach, and clinical circumstances are suggested in which the procedure may have potential therapeutic benefit.

Masses involving the adrenal in the neonate are most commonly due to hemorrhage. The literature involving the neonatal adrenal reflects this propensity. Although there have been reports of newborns with neuroblastoma [1, 2] and other tumors [3], which are more common in older children, ultrasonographic descriptions of masses involving the adrenal secondary to such tumors are rare [1]. Within a 6-month span we have discovered a clinically unsuspected adrenal carcinoma and adrenal neuroblastoma.

Four patients with primary sclerosing cholangitis (PSC) were examined with the hepatobiliary agent Tc-99m-labeled DISIDA (diisopropylphenylcarbamoyl iminodiacetic acid), and the results correlated with those of invasive cholangiography. Three of the four patients exhibited a typical pattern of multiple, persistent focal "hot spots" in the duct system, representing stasis within the segmental ductal dilatations (beading), also seen on cholangiography. Cholescintigraphy is superior to cholangiography in cases of suspected PSC where there is nonfilling of biliary radicals due to high-grade stenosis. The finding of delayed hepatic parenchymal clearance can allow estimation of the degree of obstruction of the various branches of the major bile ducts. Cholescintigraphy offers a noninvasive method of investigating patients with suspected sclerosing cholangitis, leading to earlier diagnosis. Confirmation with invasive cholangiographic procedures is recommended.
