ABSTRACT
Computed tomography was performed in two cases of blood-brain barrier (BBB) disruption due to cerebral arteriography. The first case showed diffuse contrast enhancement in the right frontotemporal region in the distribution of the middle cerebral artery; in the second case patchy contrast enhancement in both gray and white matter of both hemispheres was demonstrated. The possible mechanism for BBB disruption in these patients is discussed.

Small bowel obstruction in children with cystic fibrosis due to the impaction of barium is an unusual occurrence. This is the report of an 8.5-month-old black male who had an upper GI series on the day of discharge from the hospital, and returned the next day with a distal small bowel obstruction due to a barium impaction.

Two cases of adenoid cystic carcinoma of the trachea, and a review of the literature, are presented. This unusual and often undiagnosed tumor closely mimics asthma and chronic bronchitis. Although many patients die within 2 to 3 years of the onset of symptoms without appropriate treatment, adequate therapy should lead to survival of 10 years or more. The radiologist should make the initial diagnosis by noting the tumor, which is frequently located posterolaterally and in the middle third of the trachea.
