Magnetic resonance imaging (MRI) of the abdomen may include lower chest findings which may be overlooked or misinterpreted due to their location outside the area of main exam focus or lack of familiarity with the image appearance of these findings. This article will review the utility of abdominal MRI sequences to diagnose lower chest pathology while providing a systematic pictorial review of imaging findings in the lungs, pleura, mediastinum and chest wall. We will discuss the MRI appearance of lung nodules and masses, lung infiltrates, pulmonary infarction, pulmonary embolism, empyema, pleural effusions and thickening, mediastinal lesions and lymphadenopathy, cardiac thrombus and masses, and breast lesions. The purpose of this article is to increase awareness to the diagnostic advantages of abdominal MRI sequences for lower chest findings and encourage abdominal MRI readers to meticulous scrutinize the lower chest for concomitant pathology.

Different endemic outbreaks of measles have been diagnosed worldwide during the last several years. Some have had severe and fatal complications, possibly because of decreasing vaccination rates. The present case report describes an unvaccinated boy aged 2 years 11 months who was diagnosed with severe measles complicated by pulmonary embolism (PE). Clinical examination revealed a maculopapular rash, hyperemic pharynx, Koplik's spots, upper respiratory airway obstruction, and tachycardia with no meningeal signs of irritation. Laboratory investigations showed leukocytosis, anemia, normal liver enzyme levels, a moderately high C-reactive protein level (26 mg/L), a high erythrocyte sedimentation rate (65 mm/h), and immunoglobulin M positivity for measles. The patient was treated with antibiotic therapy (meropenem at 20 mg/kg every 8 hours) and supportive measures (anti-inflammatory drugs and intravenous rehydration). On the fourth day of hospitalization, the patient's general condition became profoundly altered; although cardiorespiratory resuscitation maneuvers were initiated, the child died. Autopsy revealed bilateral pleural effusion with serous citrine fluid, acute purulent bronchopneumonia, bilateral hilar adenopathy, and bilateral PE. Additional research is needed to establish optimal care for pediatric patients with measles, especially when complicated by PE.

A large part of the world is presently in the grip of the coronavirus disease (COVID-19) by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 virus), declared a pandemic in March 2020. This document is a brief commentary of the imaging modalities used in the screening, diagnosis and management of COVID-19 pneumonia. Chest x-rays, especially portable, still form a part of majority of official guidelines, with reports of the suggestive radiologic features. The potential of CT scan and ultrasound is also realised, with earlier detection rate. Typical radiologic findings of bilateral, asymmetrical, crazy-paved ground glass opacification, consolidation, reverse halo sign, opacities, progressing to fibrosis are well described for both the X-ray and CT scan. Atypical findings include airway changes, pleural effusion, pulmonary nodules and acute pulmonary embolism. Absence of lymphadenopathy, pleural effusion and pneumothorax is notable. The role of portable lung ultrasound, reported to be useful in emergency, is yet to be established in the guidelines. Disinfection of the equipment is a major concern. Governmental guidelines still advocate X-ray despite professional societies increasingly recommending CT scan.

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.
