PULMONARY SARCOIDOSIS

ROENTGENOLOGIC ANALYSIS OF 150 PATIENTS

A retrospective roentgenographic analysis was made of 162 patients with a tissue diagnosis of sarcoidosis.

1. Abnormal chest roentgenograms were noted in over 90 per cent of the patients at the time of positive tissue diagnosis.

2. Pulmonary sarcoidosis was most frequently diagnosed in patients 20 through 39 years of age, and was especially common in Negro women.

3. More than 80 per cent of the 150 patients with pulmonary sarcoidosis had lymph node enlargement. Bilaterality was the hallmark of this lymphadenopathy. Bilateral hilar with bilateral paratracheal lymphadenopathy was more common than bilateral hilar with only right paratracheal lymphadenopathy.

4. More than 60 per cent of the 150 patients developed pulmonary parenchymal changes during the course of the disease. A reticulonodular pattern was most common. Fibrotic and chronic acinar patterns were less frequent but common patterns.

5. Pleural effusion due to sarcoidosis was seen in 5 instances.

6. Cardiomegaly, calcified nodes, pneumothorax, lobar atelectasis, and mycetoma were unusual manifestations of pulmonary sarcoidosis.
