Atypical chest CT findings of COVID-19 pneumonia: a pictorial review

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

Evaluation of patients with fibrotic interstitial lung disease: Preliminary results from the Turk-UIP study

OBJECTIVE: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF. MATERIAL AND METHODS: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERSARS/ALAT guidelines. Demographics and clinical and radiological data of the patients were recorded. All data recorded by researchers was evaluated by radiology and the clinical decision board. RESULTS: A total of 336 patients (253 men, 83 women, age 65.8 +/- 9.0 years) were evaluated. Of the patients with sufficient data for diag-nosis (n=300), the diagnosis was IPF in 121 (40.3%), unclassified idiopathic interstitial pneumonia in 50 (16.7%), combined pulmonary fibrosis and emphysema (CPFE) in 40 (13.3%), and lung involvement of connective tissue disease (CTD) in 16 (5.3%). When 29 patients with definite IPF features were added to the patients with CPFE, the total number of IPF patients reached 150 (50%). Rate of male sex (p<0.001), smoking history (p<0.001), and the presence of clubbing (p=0.001) were significantly high in patients with IPE None of the women <50 years and none of the men <50 years of age without a smoking history were diagnosed with IPE Presence of at least 1 of the symptoms suggestive of CTD, erythrocyte sedimentation rate (ESR), and antinuclear antibody (FANA) positivity rates were significantly higher in the non-IPF group (p<0.001, p=0.029, p=0.009, respectively). CONCLUSION: The rate of IPF among patients with fibrotic ILD was 50%. In the differential diagnosis of IPF, sex, smoking habits, and the presence of clubbing are important. The presence of symptoms related to CTD, ESR elevation, and EANA positivity reduce the likelihood of IPF

Extremely rare coronary artery anomaly: Left main coronary artery

Although they are rare, left coronary artery anomalies can cause complications with high mortality, including arrhythmia and cardiac arrest. Left main coronary artery originates from the non-coronary sinus abnormality is rarely observed. This abnormality has been defined as a benign pathology in the past, although it is described in the literature to cause morbidity and mortality in some cases. We present very rare case of the left main coronary artery arising from non-coronary sinus detected on CCTA

Tıp ve diş hekimliği fakülteleri arasındaki radyolojik konsültasyon profilinin değerlendirilmesi

Amaç: Bu çalışmanın amacı; radyolojik konsültasyon amacıyla yönlendirilen hastaların başlıca yönlendirilme sebeplerini araştırarak, tıp ve diş hekimliği fakültesi arasındaki genel radyolojik konsültasyon profilinin belirlenmesidir. Yöntem: 2017-2018 tarihleri arasında, EÜ Diş Hekimliği Fakültesi Ağız, Diş ve Çene Radyolojisi AD ve E.Ü Tıp Fakültesi Radyoloji AD birimine radyolojik konsültasyon amacıyla sevk edilen tüm olguların kayıtları incelendi. Olgular; yaş, cinsiyet, konsültasyon nedeni ve mevcut patoloji lokalizasyonuna yönelik sınıflandırıldı. Elde edilen veriler tanımlayıcı istatistiksel yöntemler kullanılarak değerlendirildi. Bulgular: Toplam 80 adet radyolojik konsültasyon olgusu incelendiğinde, 65 tanesinin diş hekimliği fakültesinden tıp fakültesine; 15 olgunun ise tıp fakültesinden diş hekimliği fakültesine yönlendirildiği belirlendi. Olguların yaş ortalamasının 49 olarak belirlendiği çalışmamızda katılımcıların 44 tanesi erkek (%55) iken, 36 tanesinin kadın (%45) olduğu saptandı. Diş hekimliği fakültesinden tıp fakültesine radyolojik konsültasyon amacıyla yönlendirilen hastaların başlıca yönlendirilme sebepleri arasında malign lezyon şüphesi olan olgularda ileri tetkik gerekliliği (%39) ve cihazın görüntüleme hacmini (FOV) (Field of view) aşan geniş kemik içi lezyon varlığı (%35) yer almaktaydı. Mevcut patolojilerin en sık yerleşim bölgesi mandibula (%25) olarak belirlenirken, en sık talep edilen ileri radyografik tetkik bilgisayarlı tomografi ile görüntüleme (%48.7) idi. Tıp fakültesinden diş hekimliği fakültesine en sıklıkla yönlendirilen olguların başında ise travma olguları yer alırken (%54), bunu odontojenik kist cerrahisi sonrası kontrol (%33) ve dentofasiyal anomali olguları (%13) izledi. En sık talep edilen radyografik tetkik ise panoramik radyografi ile görüntüleme (%100) idi. Sonuç: Diş hekimliği fakültesi ve tıp fakültesinden radyolojik konsültasyon amacıyla yönlendirilen hastaların başlıca yönlendirilme sebepleri birbirinden farklılık göstermektedir. Radyolojik konsültasyon, hastanın durumunun belirlenmesi ve en uygun tedavinin planlanmasında önemli katkı sağlayacaktır.Aim: the aims of study were to evaluate main reasons of radiological consultation cases referred from both faculty of dentistry and faculty of medicine and to determine the general radiological consultation profiles between these two faculties. Methods: Cases both referred to the Radiology department of Faculty of Dentistry and Faculty of Medicine, Ege University for radiological consultation between 2017 and 2018 were evaluated. Data were classified according to the age, sex, reason for radiological consultation and location of the pathology. the variables were analysed using descriptive analysis. Results: 80 (36 females,44 males) radiological consultation cases were evaluated. 65 cases were referred to the Faculty of Medicine, while 15 cases were consulted to the Faculty of Dentistry. the mean age was 49. the most common location of the pathologies was the mandible (32.5%). “Further evaluation requirement with advanced imaging modalities” and “Intrabony lesions with dimensions extending the FOV (Field of view) of imaging modality” were the main reasons of consultation from Faculty of Dentistry, while the imaging modality frequenty requested was computed tomography (48.7%). Through the cases referred from Faculty of Medicine, “trauma cases (54%)” were the most common consultation reason followed by “control cases after the odontogenic cyst surgery (33%)” and “dentofacial anomaly cases (13%)”. Orthopantomography (100%) was the most frequently requested imaging modality. Conclusion: the main reasons of radiological consultations were different from each other. Radiological consultations in medical field have provided important contributions in terms of determining the most appropriate treatment planning and patient’s status
