Computed tomography of duodenal hematoma

As the initial study in cases of abdominal trauma, computed tomography may demonstrate intramural duodenal hematoma as an inhomogeneous, high-attenuation mass associated with obstructive changes. Representative cases show the manifestations of this injury as presented by this technique.     

Computed tomography of obstructive jaundice secondary to duodenal hematoma

Duodenal hematoma is an unusual condition, usually secondary to blunt abdominal trauma. Even more unusual is the rare development of obstructive jaundice and the attendant computed tomography findings. Nontraumatic causes of duodenal hematoma are also discussed.     

Computed tomography of retroperitoneal duodenal rupture in blunt abdominal trauma.

Two cases of retroperitoneal duodenum rupture following an upper abdominal blunt trauma are reported. Computed tomography (CT) demonstrates at best extraintestinal fluid and air in the retroperitoneum, especially if acquisition in right lateral decubitus is possible. Drawbacks of the method are also reviewed.     

MSCT评价十二指肠乳头周围憩室对胆系结石的影响

目的探讨十二指肠乳头周围憩室对胆系结石的影响。方法回顾性分析256层CT上腹部检查患者572例,对明确诊断为十二指肠憩室患者62例、胆系结石患者220例的影像资料进行回顾性分析。结果在62例十二指肠乳头周围憩室,510例十二指肠乳头周围无憩室患者中,憩室患者胆系结石发生率明显高于无憩室患者（49例79．0％、171例33．5％,P〈O．01）。结论十二指肠乳头周围憩室对胆系结石的发生有重要影响。     

Imaging of duodenal diverticula and their complications

Duodenal diverticula are common and are often incidentally found during routine imaging. Complications can occur but few require surgical intervention. We present a review of duodenal diverticula and their complications.     

十二指肠乳头旁憩室的CT表现特征

目的:探讨十二指肠乳头旁憩室的CT表现特点,提高诊断正确率。方法:回顾性分析上腹部CT检查中发现十二指肠乳头旁憩室23例,并进行上消化道造影进一步证实。结果:23例中低年资医生漏诊8例,高年资医生均诊断为十二指肠憩室。CT表现十二指肠框内圆形、半圆形囊袋状,突出于肠管小弯侧壁外,囊袋内可见气液平面,残留内容物较多时呈网状阴影,增强后囊壁强化与十二指肠壁强化一致。结论:十二指肠乳头旁憩室上腹部CT检查有一定的特征性,当疑为本病时,可进一步作上消化道造影或内镜检查。     

Computed tomography dacryocystography

Twenty-one patients with epiphora were examined by conventional dacryocystography, using Lipiodol as a contrast medium, and CT dacryocystography, using a water soluble contrast medium. In the latter, the material was not introduced under pressure but three or four drops were administered, providing a physiological method of investigation. Subsequently, CT dacryocystography provides functional information about lacrimal disorders and is easy to use.     

Computed tomography angiography

Cardiovascular disease kills more adults in the United States each year than any other medical condition. Although these diseases are largely preventable, the number of newly diagnosed patients continues to climb. Angiography traditionally involves invasive catheter examinations, but recent advances have allowed computed tomography angiography (CTA) to supplant traditional angiography as a first-line diagnostic imaging modality to assess cardiovascular disease. Often used to diagnose vascular pathologies in symptomatic patients, CTA also is useful in early detection of coronary and peripheral artery diseases. CTA will play an increasingly important role in cardiovascular medicine as technological advances improve image data acquisition, processing speeds, and image reconstruction.     

Computed tomography of gliosarcoma

Five cases of rare gliosarcoma are described with pathologic correlation. Because of its sarcomatous component, gliosarcoma tends to present as a sharply defined, round or lobulated, hyperdense solid mass with relatively homogeneous contrast enhancement and peritumoral edema. Sharp demarcation of the tumor from surrounding tissue may lead to complete removal and prolonged survival despite high malignancy. However, aggressive tumor regrowth occurs often after incomplete resection. The genesis of gliosarcoma is also discussed.     

Computed tomography of oleothorax

Oleothorax as therapy for pulmonary tuberculosis was discontinued some 35 years ago. An oleothorax may expand and cause respiratory distress. Additional complications include bronchopleural fistula and cutaneous fistula. Computed tomography has not previously been used to evaluate oleothorax. This case report describes the use of computed tomography in a patient with a symptomatic oleothorax.
