Thrombotic and nonthrombotic pulmonary arterial embolism: spectrum of imaging findings. Stein PD, Chenevert TL, Fowler SE et-al. When the artery is viewed in its axial plane the central filling defect from the thrombus is surrounded by a thin rim of contrast, which has been called the Polo Mint sign. Kang DK, Thilo C, Schoepf UJ et-al. In the thoracic area, the “polo mint sign” refers to the typical aspect of acute pulmonary embolism, when the thrombosed vessel is seen on axial planes (Fig. 1 (4): 349-57. 2009;29 (1): 31-50. If the emboli are large or there is a large clot burden, thrombolysis is an option. Acute pulmonary embolism (PE) is a leading cause of cardiovascular morbidity. Wittram C, Kalra MK, Maher MM et-al. CT angiography of pulmonary embolism: diagnostic criteria and causes of misdiagnosis. The differential diagnosis of the indirect radiologic sign of nonuniform pulmonary arterial perfusion consists of congenital or acquired causes including chronic PE, emphysema, infection, compression or invasion of a pulmonary artery, atelectasis, pleuritis, and pulmonary venous hypertension [ 2 ]. Chronic pulmonary thromboembolism (CPE) is a challenging diagnosis for clinicians. Chronic pulmonary hypertension is considered a relatively rare complication of pulmonary embolism but is associated with considerable morbidity and mortality. 20. (2011) Circulation. Chronic thromboembolic pulmonary hypertension often is identified during the diagnostic work-up in patients with unexplained pulmonary hypertension, and radiologists must be aware of its radiologic manifestations because it is a treatable cause of pulmonary hypertension in some patients.

Some disorders involving the pulmonary artery tree can radiologically mimic chronic PE including congenital interruption, vasculitides, primary sarcoma, idiopathic pulmonary hypertension, acute thromboembolism, tumor thrombus/emboli and in situ thrombosis. Because the treatment of CTEPH is markedly different from that of other types of pulmonary hypertension, lung ventilation-perfusion (V/Q) scintigraphy is recommended for the workup of patients with unexplained pulmonary hypertension.

Chronic Pulmonary Embolism. non-HIV matched controls, normal D-dimer has almost 100% negative predictive value (virtually excludes PE): no further testing is required, raised D-dimer is seen with PE but has many other causes and is, therefore, non-specific: it indicates the need for further testing if pulmonary embolism is suspected, abrupt narrowing or complete obstruction of the pulmonary arteries, if absent, another cardiopulmonary derangement is likely responsible, if unequivocally present, it can establish the need for emergent treatment, flattening or dyskinesis of the interventricular septum, CT features suggestive of right ventricular dysfunction include, abnormal position of the interventricular septum, RVD (right ventricular diameter): LVD (left ventricular diameter) ratio >1 on reconstructed four-chamber views, RVD:LVD ratio >1 on standard axial views is not considered to be a good predictor of right ventricular dysfunction, termed submassive PE when right ventricular dysfunction demonstrated on imaging (CT or echo) but without clinical hemodynamic compromise, misidentification of pulmonary veins for arteries, arterial bifurcations (or branch points) can mimic PE but usually easily distinguished on multiplanar assessment.
