Here-are my conclusions: . Subject No. 1: In 1956 there is :a ^suj)apiaal lesion -/on the right. The markings to the upper, lungs are a little prominentIn 1967 the chest appears essentially the same. . IMPRESSION: Inactive tuberculosis; no evidence of asbestosis. No. 2: In 1958 there is apical involvement on the right and multiple tiny scattered calcifications in theleft upper lung field. There is a suggestion of honeycombing at the right base. In 1963, the apical lesion on the right has disappeared. Otherwise the chest shows little change. In May 1968, the honeycombing is more striking and it is evident at both bases which are less radiolucent than earlier. IMPRESSION: Inactive tuberculosis; definite evidence of progressive asbestosis in the lower halves of the lung'fields. No. 3: The chest is normal. . yji v-h No. 4: The film is' made in expiration. There is pleural thickening obliterating the left costophrenic angle and the markings at the bases are prominent. Whether the latter s-due to milcL.inv.olvement by asbestdsis or merely represents the changes of an expiratory phase of respiration cannot be determined. I suggest a new film with deep inspiration. Films No. 5 thru No. 12 are all normal. I am returning the films to. you under separate cover, is enclosed. With best regards. S^tfierely, /V V/ My bill ETH 000099 BF/cpb Benjamin Felson, M.D E-00288
