Purpose: Radiological Society of North America (RSNA) Consensus for coronavirus disease 19 (COVID-19) is developed to evaluate the lung involvement on chest computed tomography (CT) and create a common reporting lexicon. Aim of this study is to determine the frequency of CT features in sex and age groups in patients with COVID-19, compare the findings according to the RSNA consensus classifications, and evaluate the compatibility of the classifications and findings.
Materials and Methods: Chest CT images of 281 patients with COVID-19 were evaluated. Patients were noted in the appropriate RSNA consensus class. The patients’ data were analyzed by group according to age and sex.
Results: The main findings included ground-glass opacity, consolidation, and air bronchogram. The common involvement patterns were as follows: bilateral, peripheral, and multifocal. The rates for the typical, atypical, and indeterminate classifications, according to the RSNA consensus, were 63.6%, 9.6%, and 27.0%, respectively. Subpleural fibrous streaking was more frequent in males. Air bronchogram, lymphadenopathy, pleural effusion, subpleural fibrous streaking, bilateral involvement, and a typical classification on CT features were more frequent in the ≥ 65-year age group.
Conclusion: While the typical appearance classification has results consistent with the findings, we think that the classifications specified as indeterminate and atypical appearance do not show sufficient agreement with the findings and revision is needed for correct diagnostic guidance.
IntroductionMorgagni hernia is a rare congenital anomaly caused by the fusion defect between the septum transversum and the sternum. Patients may be asymptomatic or present with respiratory symptoms, abdominal pain, retrosternal pain, abdominal fullness, or gastrointestinal obstruction. Chest X-ray and thoracic computed tomography (CT) are the most commonly used modalities in imaging.AimWe describe an adult case in which the transverse colon was herniated from the retrosternal area to the thyroid gland without a history of trauma or surgery.Case studyA 24-year-old female patient living in the countryside presented to our hospital with the complaints of indigestion and chest pain persisting for 2 years. In the thorax CT examination of the patient, it was observed that the transverse colon had herniated to the retrosternal region and then to the neck.Results and discussionMost acquired anterior diaphragmatic hernias are due to blunt or penetrating traumatic injury. However, there are also case reports describing iatrogenic diaphragmatic hernias following a sternotomy performed during thoracic or cardiac surgery. In Morgagni hernia, the most frequently herniated organs are the greater omentum and transverse colon. There are also reports, albeit rarer, describing the herniation of the stomach, liver and small intestines.ConclusionsMorgagni hernia is a very rare type of hernia, especially in adult patients. The diagnosis of these patients can be easily made based on thoracic CT findings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
