Three patients are described with unusual collections of cholecystographic contrast material in the right upper abdomen medial and posterior to the gallbladder, in a characteristic "incomplete ring" configuration. Subsequent barium examinations of the upper gastrointestinal tract proved each of these collections to represent contrast material trapped in active duodenal ulcer craters. This cholecystographic sign, though uncommon, is believed to be fairly specific for duodenal ulcer. Recognition of the "incomplete ring" sign should prompt the radiologist to obtain barium studies necessary to confirm the presence of ulcer.
本文描述了3例患者，其右上腹胆囊内侧和后方有异常的胆囊造影剂聚集，呈特征性的“不完整环形”形态。随后的上消化道钡剂检查证实，这些造影剂聚集均为活跃的十二指肠溃疡龛内潴留的造影剂。这种胆囊造影征象虽不常见，但被认为对十二指肠溃疡具有较高的特异性。认识到“不完整环形”征象应促使放射科医生进行必要的钡剂检查以证实溃疡的存在。
