View Original Source →Case Details
Personal Characteristics
An asymptomatic 28-year-old man
Clinical Characteristics
2 centimeter nodule situated in the peripheral and posterior portion of the left midlung field. The nodule had been discovered on routine x-ray examination of the chest. Tomography demonstrated calcification typical of granuloma. The histoplasmin skin test gave positive result and the tuberculin test a negative result. The patient returned in 1969 after left pleural effusion developed. The effusion was minimal and did not recur after thoracentesis. No explanation could be offered for the disappearance of the nodule, noted at this time , and unfortunately no interim roentgenograms of the chest were available. Bronchoscopic examination performed because of the remote possibility that the nodule might be obscured by an atelectatic left lower lobe gave negative results.
