Warfarin-induced tracheobronchial calcification.

Calcification of the trachea and proximal bronchi is a common, normal finding on chest radiographs in the elderly population, especially in women. More extensive airway calcification is also a rare manifestation of many pathologic conditions. The authors report a case of pathologic tracheobronchial calcification associated with long-term warfarin therapy. Chest radiographs showed prominent, diffuse calcification of the tracheobronchial tree. Computed tomography showed extensive calcification of the airway walls, extending from the trachea to the lung periphery.

Six cases of acute central pulmonary embolism revealed on unenhanced multidetector CT of the chest.

OBJECTIVE: Our purpose was to describe the imaging findings of central pulmonary embolism on unenhanced multidetector CT (MDCT) of the chest. CONCLUSION: Unenhanced MDCT of the chest is often performed for the evaluation of nonspecific chest symptoms. Awareness of the rare finding of a high-attenuation centrally located pulmonary embolism on unenhanced MDCT is important because acute pulmonary embolism may be identified when it is not suspected clinically, and such detection can determine further imaging needs and allow the timely initiation of appropriate therapy.

Detection of central pulmonary embolism on computed tomography densitometry images before computed tomography pulmonary angiography.

OBJECTIVE: The purpose of this article is to describe the imaging findings of acute central pulmonary embolism on computed tomography (CT) densitometry images performed before contrast-enhanced CT pulmonary angiography. METHODS: A retrospective review was conducted of reports from all CT pulmonary angiograms performed at our institution, and cases of acute central pulmonary embolism, defined as those with clot in the main, left, or right pulmonary arteries, were identified. Images of positive studies were reviewed on a picture archiving and communications system (PACS) workstation. RESULTS: A total of 1282 CT pulmonary angiograms were obtained for evaluation of possible acute pulmonary embolism, and 1 combined CT aortogram and pulmonary angiogram was performed for aortic dissection and acute pulmonary embolism. Two hundred fourteen (16.7%) examinations positive for acute pulmonary embolism were identified, 26 (12.1%, 2.0% of total examinations) of which had central clots. Of the 26 patients with central acute pulmonary embolism, 12 (46.1%, 5.6% of all positive studies and 0.9% of all CT pulmonary angiograms) had clots that were visible on the densitometry images. CONCLUSION: Although an uncommon finding, acute central pulmonary embolism can be detected on CT densitometry performed to optimize opacification of the pulmonary arteries for CT pulmonary angiography and may prove useful in selected clinical situations.
