Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . The heart size is normal . No configurational abnormalities identified . Thoracic aorta unremarkable . No mediastinal abnormalities are seen . The pulmonary vasculature is normal . No signs of acute or chronic parenchymal infiltrates are present and the lateral and posterior pleural sinuses are free . No pneumothorax in the apical area . Mildly accentuated kyphotic curvature in the thoracic spine as seen on the lateral view is related to a mild anterior wedge - shaped deformity of a vertebral body in the mid portion of the thoracic spine , probably T7 . No other skeletal abnormalities are identified . Comparison is made with the next preceding available PA and lateral chest examination of ___ . The findings are completely unchanged . Thus , no evidence of reoccurring apical pneumothorax . Also , the mild deformity of a mid thoracic spine vertebral body appears unchanged . Review is extended to two preceding chest examination of ___ and the diagnosis of a tiny apical pneumothorax made at that time is questionable .
    OUTPUT:
    
No evidence of pneumothorax . Normal chest findings .
