Abstract Background Pulmonary embolism (PE) is a common condition with considerable morbidity and mortality; it is more often diagnosed post-mortem by pathologists than in vivo by clinicians. Prompt and accurate diagnosis is difficult because PE may be clinically silent, the symptoms are vague and nonspecific, and in addition there is no definitive, non-invasive diagnostic test to establish its diagnosis. Objectives The aim of this study is to discuss the reliability and clinical effectiveness of the incidental detection of a PE on non-contrast CT which could be advantageous in the emergent context and also in patients with pre-existing renal disease or known allergies to contrast agents in a situation without viable alternative. Patients and Methods Results In our study CTA was used as the method of choice in detection of central pulmonary embolism in highly suspected pulmonary embolism in twenty patients and we compared it with pre contrast scan to identify non contrast CT reliability in detection of central pulmonary embolism. Our study showed that non contrast CT chest have a good role in detection of central pulmonary embolism as hyper dense lumen sign. Conclusion Unenhanced MDCT is an alternative approach for the diagnosis of acute central PE when CTPA is inaccessible or contraindicated. In our study Non-contrast chest CT scans have good role in evaluation of PE through detection the hyper dense lumen sign that is a good indicator of acute pulmonary thromboembolism particularly in cases involving the central pulmonary arteries.

We present a case of an acquired, transient, rotated right kidney in a 43-year-old woman with an enterocutaneous fistula who presented with acute pulmonary embolism. This non-ptotic rotated kidney returned to its normal orientation within 10 days. We postulate that this transient kidney rotation is due to transient hepatomegaly and passive renal congestion secondary to pulmonary embolism. While in this patient there were no untoward sequelae, it has been reported that ureteral obstruction or vascular occlusion can occur in patients with ptotic and malrotated kidneys, and radiologists, therefore, should be aware of this unusual occurrence and the potential complications.

Background: Acute pulmonary thromboembolism (APTE) is a life-threatening condition, often manifesting with chest pain, dyspnea, and increased cardiac biomarkers including cardiac troponin I (CTI) and D-dimer. Therefore, APTE is often misdiagnosed with classical non-ST elevation myocardial infarction (NSTEMI), resulting in unnecessary coronary interventions and a delay of therapy. Objectives: Our aim was to distinguish APTE from NSTEMI based on CTI and D-dimer levels. Methods: Complete clinical and laboratory data sets from APTE patients (n = 123) were compared with matched NSTEMI patients (n = 123) who presented with chest pain. The APTE diagnosis was confirmed by chest tomography, angiography, or radionuclide ventilation-perfusion scan, while NSTEMI was established by clinical symptoms, cardiac biomarkers, and coronary angiography. Clinical characteristics, CTI (initial and peak), and D-dimer levels at presentation were retrospectively analyzed. Results: The clinical characteristics were not different between APTE and NSTEMI patients. However, significantly lower initial CTI (0.2 ± 0.5 vs. 4.4 ± 9.5 ng/ml) and peak CTI (0.7 ± 2.7 vs. 17.1 ± 20.4 ng/ml), but higher initial D-dimer (9.8 ± 9.4 vs. 1.6 ± 3.6 ng/ml), distinguished APTE from NSTEMI. By receiver operating characteristic curve analysis, the cutoff values for initial CTI, peak CTI, and D-dimer were 0.25, 0.98, and 3.18 ng/ml, respectively. Conclusion: Patients with APTE exhibited lower initial and peak CTI but higher D-dimer levels than NSTEMI patients. Assessing cardiac biomarkers is useful for differentiating APTE from NSTEMI. Further large randomized biomarker studies are urgently needed to facilitate a better APTE diagnosis since clinical characteristics are not particularly helpful.
