title: Episodic ectopic ACTH syndrome associated with pulmonary infarctions.
abstract: The etiology of the ectopic ACTH syndrome, associated with certain tumors, is unclear. The ectopic ACTH syndrome was diagnosed in our patient by the characteristic clinical and laboratory findings. Shortly after admission, pulmonary infarctions were documented by lung scans and computed tomography. After treatment with anticoagulants, his plasma ACTH level and its suppressibility became normal. There was no evidence of a tumor. The ectopic ACTH syndrome recurred one year later in conjunction with another episode of pulmonary infarctions. During anticoagulant therapy his infarctions cleared and his plasma ACTH level normalized. In the five years since the onset, no tumor has been found, and plasma ACTH level remains normal and suppressible. We propose that our patient's pulmonary infarctions stimulated pulmonary ACTH production, leading to Cushing's syndrome.
