Demonstration of two cases of uncommon lung disease, with emphasis on the chest X-ray.

A patient with a unilateral obstructive emphysema due to a centrally localized carcinoid of the bronchus is presented. The chest X-ray is very suggestive; nevertheless, the diagnosis is often delayed. A patient with echinococcosis of the lung is described. A Turkish woman presented with multiple varying round masses, hydatid cysts. A short description of the disease is given. As in the previous case the chest X-ray is suggestive of the diagnosis if one takes into account the nationality of the patient. The case histories of 2 patients with an uncommon disease of the lungs elucidated by misleading and/or unexpected radiologic findings, will be presented in detail.
