Children account for a small proportion of total COVID-19 cases ranging from 1% to 15%. Around 90% of children with COVID-19 were either asymptomatic or had mild-to-moderate disease and only less than 5% had severe disease. Chest imaging plays a vital role not only in diagnosing COVID-19 pneumonia but also in monitoring disease progression and evaluating therapeutic response. However, radiological findings are milder and less specific in children., We report an 11-year-old male child with COVID-19 pneumonia who presented with atypical findings on chest imaging.
An 11-year-old male child presented with fever, cough, cold, and respiratory distress for 3 days duration. His father was recently diagnosed as coronavirus disease (COVID-19) positive. The child was developmentally normal and had no prior history of any respiratory disease. Examination revealed a febrile, tachypneic child with SpO2 of 94% in room air. His pulse was 106/min and respiratory rate was 34/min. Nasopharyngeal swab test for COVID-19 by reverse transcription polymerase chain reaction came as positive. Chest X-ray showed perihilar bronchial wall thickening, bilateral small parenchymal nodules, and lower zone opacification [Figure 1]. Ultrasound chest revealed left-sided minimal pleural effusion. High-resolution computed tomography (CT) of the chest showed multiple ill-defined, pleural-based isodense nodular areas in the right middle lobe, left upper lobe, and lower lobe and multiple, small, subcentimetric-sized well-defined nodular opacities in bilateral lung parenchyma diffusely [Figure 2]. Level of suspicion was estimated as COVID-19 Reporting and Data System-3. He was diagnosed as a case of COVID-19 pneumonia and was treated with supplemental oxygen, antivirals, antibiotics, and low-dose glucocorticoids. Symptoms improved gradually, and he was discharged after 14 days. He is doing well on follow-up at 4 weeks.

Chest radiograph findings in children with COVID-19 infection are nonspecific, which includes common findings such as diffuse interstitial pattern and increase in central peribronchovascular wall thickening., The classic findings of pediatric COVID-19 in noncontrast chest CT imaging includes subpleural lesions, bilateral multifocal ground-glass opacification, patchy consolidation, and halo sign around areas of consolidation., Lesions are frequently wedge shaped, followed by elongated and confluent with ill-defined margins. With increasing severity of lung disease, the consolidations can extend diffusely resulting in “;white-out lung” along with extensive air bronchograms., When compared to adults, children are more likely to demonstrate CT abnormalities but less likely to have bilateral and interstitial involvement. Nodular lesions, though reported in adults, are uncommon in children.,
Radiologists should have a sound knowledge of these atypical imaging patterns and a high index of suspicion while dealing with pediatric COVID-19 cases to avoid misdiagnosis.
