    Abstract Situs inversus totalis (SIT) describes a complete mirror image of the visceral organs in the thoracic and abdominal cavities. Dextrocardia, in combination with SIT, is a rare congenital anomaly with a frequency of 1:10 000, and coronary heart disease may occur with a similar frequency and manifestation as in the general population. Coronary computed tomography (CT) angiography is useful for accurately assessing the coronary artery origin and position for preprocedural planning of difficult coronary artery catheterisation in SIT. In this case, invasive coronary angiography (ICA) was performed from the same angle but on the opposite side compared to standard angiography. With the use of volume-rendered three-dimensional and curved reformatted images reconstructed from coronary CT angiography, the advancement of guidewires and catheters during ICA as well as the planning of surgical procedures can be performed more safely.

    Abstract Although real-time polymerase chain reaction (RT-PCR) remains the standard reference for a definitive diagnosis of coronavirus disease 2019 (COVID-19) infection, the false-negative rate and the lack of availability of RT-PCR assays in the early stages of the outbreak restricted the prompt diagnosis of infected patients. Since most COVID-19 infected patients were diagnosed with pneumonia based on characteristic imaging patterns, radiological examinations have become vital for early diagnosis and the assessment of disease course. Although chest radiography is not sufficiently sensitive for the detection of small ground-glass opacity (GGO) and may produce normal findings in the early stage of infection, it can be used as an initial imaging method, especially in young patients. Thin-slice chest computed tomography (CT) plays a vital role in early detection, observation, and disease evaluation. Typical CT findings of COVID-19 include peripherally distributed multifocal GGOs with patchy consolidations and predilection for the posterior part or lower lobe involvement. The increasing numbers, extent, and density of GGOs on CT indicate disease progression. Lung involvement progresses to consolidation up to 2 weeks after disease onset. Clear and frequent communication among health-care providers, including radiologists, is vital for the improvement of patient care during this pandemic.

    Abstract Abstract Background There is no consensus on the imaging modality to be used in the diagnosis and management of Coronavirus disease 2019 (COVID-19) pneumonia. The purpose of this study was to make a comparison between computed tomography (CT) and chest X-ray (CXR) through a scoring system that can be beneficial to the clinicians in making the triage of patients diagnosed with COVID-19 pneumonia at their initial presentation to the hospital. Results Patients with a negative CXR (30.1%) had significantly lower computed tomography score (CTS) (p < 0.001). Among the lung zones where the only infiltration pattern was ground glass opacity (GGO) on CT images, the ratio of abnormality seen on CXRs was 21.6%. The cut-off value of X-ray score (XRS) to distinguish the patients who needed intensive care at follow-up (n = 12) was 6 (AUC = 0.933, 95% CI = 0.886–0.979, 100% sensitivity, 81% specificity). Conclusions Computed tomography is more effective in the diagnosis of COVID-19 pneumonia at the initial presentation due to the ease detection of GGOs. However, a baseline CXR taken after admission to the hospital can be valuable in predicting patients to be monitored in the intensive care units.

    Abstract Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first reported in Wuhan, China. The infection rapidly spread to more than 200 countries around the world. The clinical presentation of the disease may vary from mild illness to severe pneumonia such as acute respiratory distress syndrome (ARDS). The chest computed tomography (CT) has an important complementary role in diagnosis of the disease. The predominant CT findings of the disease are ground glass opacities and consolidations located in subpleural areas of lower lobes. Widespread ground-glass opacities, consolidation, air bronchograms, central involvement of lung parenchyma, mediastinal lymphadenopathy are more common in patients with the severe form of the disease. CT imaging also guides in differentiation of alternative diagnosis or in assessment of associated pulmonary embolism during the course of the disease. In this pictorial review we aim to review the CT features of COVID-19 pneumonia and mention the changes throughout the disease process.

    Abstract Coronavirus disease 2019 (COVID-19) first emerged in China and rapidly spread in the world causing a pandemic. Chest computed tomography (CT) continues to play an important role in the diagnosis and follow-up of the disease due to shortcomings of the real-time reverse transcription-polymerase chain reaction test, which is the gold standard in the diagnosis of this disease. Typical chest CT findings of COVID-19 pneumonia have been widely reported in the literature. However, atypical findings such as central involvement, peribronchovascular involvement, isolated upper lobe involvement, nodular involvement, lobar consolidation, solitary involvement, pleural and pericardial fluid, and subpleural sparing can also be seen. Knowing these atypical findings is important to avoid misdiagnosis. This review summarizes the atypical findings that can be seen in the course of the disease and may be confused with other diseases.

    Abstract Abstract Background Right ventricular pseudoaneurysm is an extremely rare finding than left ventricular pseudoaneurysm, associated with high mortality. The diagnosis of right ventricle pseudoaneurysm is often challenging because of its rarity and lack of typical clinical features. However, advanced cardiac imaging techniques including CT angiogram and MRI can help a timely diagnosis to avoid a fatal outcome. Case presentation The authors present the imaging findings of a right ventricular pseudoaneurysm in a 33-year-old male, presented with dyspnea and chest pain after exertion for 2 weeks. The gated CT and cardiac MRI showed a small outpouching from the right ventricle apex into the pericardial space, consistent with a pseudoaneurysm. He underwent cardiac surgery and pseudoaneurysm resection with a favorable outcome. Conclusion Right ventricular pseudoaneurysm is a very rare complication following right heart catheterization and a potentially life-threatening condition that requires prompt diagnosis and management. Though the lack of its typical clinical presentation is often a diagnostic challenge, advanced cardiac imaging techniques including CT angiogram and MRI may help a timely diagnosis to avoid a fatal outcome.

    Abstract The present study aimed to investigate growth, survival and reproduction of the Turkish medicinal leech, Hirudo sulukii, endemic to Southeastern Anatolia and whose biology is poorly understood. In comparison with the Southern medicinal leech, Hirudo verbana, which has a wide distribution throughout Eurasia, H. sulukii grew faster until the fourth month, then growth increased significantly in favour of H. verbana. At the beginning of gravidity, high mortality occurred in specimens of H. sulukii not transferred to moist peat, the cocoon deposition area. Gravidity occurred in almost all (98%) H. sulukii adults, but was detected in only 60% of H. verbana adults. Unlike the growing period, survival rate was greater in H. sulukii during the reproductive period. Gravidity and cocoon laying periods lasted longer in H. sulukii, which continued reproductive activity even in colder conditions. There were more and smaller sized cocoons having higher deformation rate in H. sulukii. Likewise, fewer and larger offspring having lower morphological abnormality were observed in cocoons having lower hatchling rates in H. sulukii. Collectively, our findings reveal that H. sulukii reaches adult size relatively early, continues its reproduction in cold conditions and displays high reproductive performance, thus making it a strong candidate for leech aquaculture.

    Abstract Objective: In this study, we aimed to determine the prevalence of gynecomastia by evaluating computed tomography (CT) images of male patients who were admitted to our hospital during the coronavirus disease-2019 (COVID-19) pandemic.
    Materials and methods: This study included a total of 1,877 patients who underwent chest CT for prediagnosis of COVID-19 pneumonia between March 15
    Results: The prevalence of gynecomastia was 32.3%. In terms of pattern, 22% were nodular, 57% were dendritic, and 21% were diffuse glandular gynecomastia. A significant correlation was found between age and gynecomastia pattern (p<0.001). The incidence of nodular, dendritic, and diffuse glandular gynecomastia increased with advancing age. A significant difference was found in the analysis of the correlation between age groups and glandular tissue diameters (p<0.001). With an increase in glandular tissue diameter, the gynecomastia pattern changed from a nodular to a diffuse glandular pattern.
    Conclusion: In our study, gynecomastia diagnosis was made through axial CT images. Although CT should not replace mammography and ultrasonography for clinical diagnosis of gynecomastia, chest CT scans can be used to evaluate patients with suspected gynecomastia.
