    INPUT: PA and lateral chest views were obtained with patient in upright position . Comparison is made with the next preceding PA and lateral chest examination of ___ . Heart size is unchanged and within normal limits . Thoracic aorta mildly elongated but otherwise unremarkable . The pulmonary vasculature is not congested . Comparison is made with the next preceding chest examination . There exist some hazy right - sided basal densities in supradiaphragmatic position . These include a local 1 x 1 .5 cm density which appears to be a parenchymal infiltrate . Comparisons made of the lateral projections demonstrate a hazy density occupying the area close to the lower portion of the right - sided major fissure , thus locating the process to either the lower aspect of the right middle lobe or adjacent anterior segment of the right lower lobe . Under any circumstances , a followup after treatment in about a week or so is recommended to see normalization of these findings to a status as they existed on the preceding chest examination of ___ , which was considered to be within normal limits .
    OUTPUT:
    
Infiltrate on right lower lung anteriorly , probably pneumonic . Followup recommended .
