case_images: Timeline of symptom progression and clinical events leading to hospital admission. The diagram illustrates the patient's clinical course from symptom onset (Day 0) to hospital admission (Day 7). The patient's recent domestic trip to a resort in Angra dos Reis, located two hours by car from Rio de Janeiro, was uneventful and posed no risk of tropical or endemic infections. Key events highlight the progression from mild respiratory symptoms to severe disease, marked by hypoxia and fatigue, necessitating hospitalization. Therapeutic interventions and diagnostic milestones are also described.

case_images: On (D7), he was admitted to the Emergency Department with SpO2 levels of 91-92% on room air, tachypnea, fatigue, an axillary temperature of 37.8  C, and blood pressure of 140/80 mmHg. (Figure 1).
case_images: Axial computed tomography (CT) image of the thorax. The image shows bilateral ground-glass opacities with a reticular pattern interspersed with focal areas of consolidation and peripheral bronchiolar filling. The red arrows highlight specific areas of consolidation surrounded by ground-glass opacities, which are more prominent in the peripheral and lower lung regions. These findings suggest a diffuse inflammatory or infectious process involving the pulmonary interstitial and peripheral airways (acinus and bronchioles), which is consistent with viral pneumonia.

case_images: Imaging studies revealed significant pulmonary involvement (Figure 2).
case_images: Computed tomography (CT) image of the paranasal sinuses in the sagittal plane. The image shows mucosal thickening and partial opacification in the frontal sinus (highlighted by the superior red arrow) and ethmoid air cells (highlighted by the inferior red arrow). Narrowing of the sinus drainage pathways is also evident. These findings are consistent with those of acute and subacute sinusitis.

case_images: Additionally, CT scans of the paranasal sinuses showed mucosal thickening associated with secretions in the frontal sinuses and ethmoidal cells bilaterally, along with mild mucosal thickening in the maxillary sinuses, consistent with sinusitis (Figure 3).
