Example #5
Chronic Pulmonary embolism (PE) and Deep Venous Thrombosis (DVT): A 49 year old man with sudden onset of shortness of breathSOB. Doppler ultrasound examination of the lower extremities revealed femoral vein thrombus. VQ scan showed complete lack of perfusion of the right lung. A markedly dilated azygous vein is identified. Also, dilated azygous and hemiazygous veins are identified in the retrocrural space. There is acute thrombus within the common iliacs, external and internal iliac veins, and common femoral veins bilaterally. Above the confluence of the common iliac veins, the inferior vena cava is inapparent. Multiple collateral vessels are present around the aorta and the azygous and hemiazygous veins are prominent. The portal venous axis is patent.

Example #6

 * Central PE: 76 year old female had right lower lobe resection for stage II non-small cell carcinoma of the lung. Chest X-ray and CT images shown below.


 * 1) Chronic pulmonary embolism within the right pulmonary artery.
 * 2) Persistence of air within the decreased right pleural fluid collection with adjacent retraction of inflamed esophagus raises the suspicion for esophageal pleural fistula.

Example #7

 * Bilateral PE: A 74 year old male with recently diagnosed diabetes mellitus who presents with left sided chest pain and abdominal pain with a 50 pound weight loss.

The scan is performed to evaluate for occult malignancy. The patient has an apparent pulmonary embolus. Thoracoabdominal CT findings are as follow:

 * 1) Bilateral pulmonary thromboemboli involving both upper and both lower lobe pulmonary arteries, greater on the right side.
 * 2) Wedge shaped, pleural based opacities in the left upper lobe which may represent pleural effusions are probably related to the emboli.
 * 3) Dilated right ventricle. This may also be related to the pulmonary emboli.
 * 4) No signs of mass or lymphadenopathy.
 * 5) No evidence of malignancy or other significant abnormality within the abdomen or pelvis.
 * 6) Incidental findings included small calcification in the right adrenal gland, small left renal cyst, and enlarged prostate gland.
