ABSTRACT
The primitive trigeminal, otic, hypoglossal, and proatlantal intersegmental arteries are fetal anastomoses between the carotid and vertebrobasilar systems. Persistent trigeminal artery (PTA) is the most frequent embryonic communication between the vertebrobasilar and carotid systems in adults. We report a case of PTA compressing the left side of the pituitary gland and stalk, in a patient with elevated blood prolactin level.

Intestinal obstruction secondary to gallstones is seen in the older population and the level of obstruction is usually at the level of the terminal ileum. Obstruction at the level of the gastric outlet is called Bouveret's syndrome. A case with perforated cholecystitis and duodenal obstruction due to a gallstone is presented. The CT findings are presented along with the clinical findings and literature review.
