Summarize the radiology report findings into an impression within 3 sentences.
    INPUT: PA and lateral chest views were obtained with patient in upright position . Available for comparison is the next preceding chest examination of ___ . On the present examination , the heart size is within normal limits , and no configurational abnormalities are identified . The pulmonary vasculature is not congested . On the right lung base and located in the posterior segment of the right lower lobe , there is a discrete parenchymal density indicative of a pneumonic infiltrate . There is no pleural reaction and the right lateral as well as posterior pleural sinus is free from any fluid accumulation . The left lung base is unremarkable . On the frontal view , one can identify , in the right apical area , some scattered small parenchymal infiltrates overlying partially the proximal clavicular area and reaching the apical pleural space . The left apical area appears free , and no pneumothorax is present . Comparison with the next preceding chest examination of ___ enables one to clearly identify the right lower lobe pneumonia as being new . Similarly , the right apical area was clean on the preceding examination . One can also see that there are some linear densities from the right hilum into the direction of the right apical area . The appearance of the lesion , although not typical , raised the possibility of specific tuberculous infection . Noteworthy is that on the preceding examination in ___ , the heart size was considerably larger than it is now , although it might still have been within normal limits .
    OUTPUT:
    
New acute infiltrates in right lower lobe posterior segment and additional right apical lesion raising the possibility of specific infection . Further followup is indicated . Referring physician , ___ , was paged but was not listed .
