Evaluation of the Compatibility of Atrium and Ventricular Measurements in Thoracic Computerized Tomography and Coronary Computerized Tomography Angiography

Aim: We aimed to evaluate the consistency of the measurements of diameter and area of cardiac chambers in coronary computed tomography angiography (CTA) and contrast-enhanced thoracic computed tomography (CT) images.Materials and Methods: 30 patients who underwent thoracic CT and coronary CTA over a 6-month period between August 2016 and August 2019 were included in the study. Maximum left atrium area, anteroposterior and transverse left atrium diameter, right atrium transverse diameter, right and left ventricular transverse diameters were measured by two observers. Inter-observer and intra-observer Contrast-enhanced thoracic CT and coronary CTA measurements of the cardiac chambers were found to be perfectly compatible. Both left atrial axial area and AP diameter were evaluated on coronary CTA images and contrast-enhanced thoracic CT with excellent reproducibility.Conclusion: To our knowledge, this is the first study that shows the measurement of diameter and area of the cardiac chambers in thoracic CT and coronary CTA and comparing them with each other. Thoracic CT, with its high reproducibility, could be a useful tool in evaluation of cardiac chambers

Percutaneous transcatheter embolization of gastrointestinal bleeding in a child with polyarteritis nodosa

Background: Polyarteritis nodosa is a form of necrotizing vasculitis of small and medium-sized arteries. Major gastrointestinal complications are ulceration, perforation, hemorrhage, and obstruction. Case Report: We report on a clinical case of a 16-year-old female patient with massive hematemesis, who was successfully treated with embolization with a 1:2 dilution of N-butyl cyanoacrylate glue. Conclusions: To the best of our knowledge, this is the youngest child reported on with massive GI bleeding secondary to PAN, treated with successful percutaneous transcatheter embolization under emergency conditions

Videofluoroscopic and Manometric Evaluation of Oropharyngeal and Esophageal Motility Disorders

Background: Esophageal motility studies are performed in patients who have dysphagia that is not explained by stenosis. Diagnosis can be challenging and requires expertise in the interpretation of tests and symptoms

Apparent Diffusion Coefficient Measurement in Mediastinal Lymphadenopathies: Differentiation between Benign and Malignant Lesions.

Objectives: We aimed to prospectively assess the diagnostic value of apparent diffusion coefficient (ADC) measurement in the differentiation of benign and malignant mediastinal lymphadenopathies. Materials and Methods: The study included 63 consecutive patients (28 women, 35 men; mean age 59.3 years) with 125 mediastinal lymphadenopathies. Echoplanar diffusion-weighted magnetic resonance imaging of the mediastinum was performed with b-factors of 0 and 600 mm(2)/s before mediastinoscopy and mediastinotomy, and ADC values were measured. The ADC values were compared with the histological results, and statistical analysis was done. P < 0.05 was considered statistically significant. Results: The mean ADC value of malignant mediastinal lymphadenopathy (1.030 +/- 0.245 x 10(-3) mm(2)/s) was significantly lower (P < 0.05) when compared to benign lymphadenopathies (1.571 +/- 0.559 x 10(-3) mm(2)/s). For differentiating malignant from benign mediastinal lymphadenopathy, the best result was obtained when an ADC value of 1.334 x 10(-3) mm(2)/s was used as a threshold value; area under the curve 0.848, accuracy 78.4%, sensitivity 66%, specificity of 86%, positive predictive value 76.7%, and negative predictive value of 79.2%. Interobserver agreement was excellent for ADC measurements. Conclusions: ADC measurements could be considered an important supportive method in differentiating benign from malignant mediastinal lymphadenopathies

Life-Threatening Complication of Percutaneous Transthoracic Fine-Needle Aspiration Biopsy: Systemic Arterial Air Embolism

Computed tomography-guided percutaneous transthoracic fine-needle aspiration biopsy of lung lesions is a well known diagnostic technique. Nevertheless, it has some complications; such as pneumothorax, intraparenchymal hemorrhage and hemoptysis, which are not rare. Air embolism is one of the rare but potentially fetal complications of this procedure. Herein, we report the case of a 69-year-old male, in which case of systemic air embolism developed after the performance of lung biopsy. Early diagnosis and prompt oxygen therapy is crucial for patient's survival so careful reviewing of the obtained computed tomography images during the biopsy may prevent a missing systemic air embolism and provide an adequate therapy

Laparoscopic Management of a Very Rare Case: Cystic Artery Pseudoaneurysm Secondary to Acute Cholecystitis

Pseudoaneurysm of a cystic artery is a rare entity that commonly occurs secondary to biliary procedures. Most of the cases in literature are consisted of ruptured aneurysms and to our knowledge, except our case, there were only 3 cases with unruptured aneurysms, which incidentally were detected by radiological methods. When cystic artery pseudoaneurysm is present with acute cholecystitis, most of the reports in literature suggested open cholecystectomy with the ligation of the cystic artery as a main treatment option. In this paper we present a case of acute cholecystitis with unruptured cystic artery pseudoaneurysm that incidentally was detected by computed tomography (CT). Cystic artery pseudoaneurysm was handled laparoscopically with simultaneous cholecystectomy. Due to high risk of rupture, surgeons have evaded laparoscopic approach to acute cholecystitis, which accompanied cystic artery pseudoaneurysm. However herein, we proved that laparoscopic management of cystic artery pseudoaneurysm with simultaneous cholecystectomy is feasible and reliable method

Cement embolism confused with involvement of tuberculosis on plain graph

Although percutaneous vertebroplasty was first used in the treatment of vertebral hemangiomas, in time, it took part in the treatment of painful osteoporotic and pathological vertebral fractures. Cement embolism is a rare complication of vertebroplasty and usually remains asymptomatic; however, sometimes it may lead to fatal results. In this article, we report a 47-year-old female patient of cement embolism diagnosed by thorax computed tomography that was confused with involvement of tuberculosis due to incidentally detected high-density pulmonary opacities on plain graph. We also discussed other pathologies which should be considered in differential diagnosis when pulmonary opacities are identified
