Sample Report
Findings concerning for a right upper lobe pulmonary abscess with adjacent mediastinitis. No mediastinal gas or drainable mediastinal fluid collection. Recommend follow-up imaging after treatment to ensure resolution.
Groundglass opacities and tree-in-bud nodularity throughout the right lung likely relate to atypical infection.
Large pericardial effusion, likely representing reactive pericarditis. Recommend correlation with clinical findings of cardiac tamponade.
