Adrenal myelolipoma is a benign adrenocortical tumor composed of adipose tissue and bone marrow elements; it is reported in one out of 500–1250 autopsy cases. Adrenal myelolipoma is typically diagnosed…
When a patient with multiple endocrine neoplasia type 1 (MEN-1) presents with Cushing syndrome (CS), it may be corticotropin (ACTH) independent (e.g., adenoma, carcinoma, or bilateral macronodular adrenal hyperplasia) or…
Most patients with corticotropin (ACTH)-dependent Cushing syndrome (CS) will have an ACTH-secreting pituitary microadenoma. Approximately 15% of patients with ACTH-dependent CS have an ectopic source of ACTH secretion. The most…
Most patients with corticotropin (ACTH)-dependent Cushing syndrome (CS) will have an ACTH-secreting pituitary microadenoma. Approximately 15% of patients with ACTH-dependent CS have an ectopic source of ACTH secretion, with the…
Most patients with corticotropin (ACTH)-dependent Cushing syndrome (CS) will have an ACTH-secreting pituitary microadenoma. When the pituitary appears normal on magnetic resonance imaging (MRI), it is important to distinguish between…

Approximately 15% of patients with corticotropin (ACTH)-dependent Cushing syndrome (CS) have an ectopic source of ACTH secretion, with the most common source being a bronchial carcinoid (≈25%). Ectopic CS resulting…
Most patients with corticotropin (ACTH)-dependent Cushing syndrome (CS) will have an ACTH-secreting pituitary microadenoma—50% of which are so small that they cannot be seen on magnetic resonance imaging (MRI). Pituitary-dependent…
Most patients with corticotropin (ACTH)-dependent Cushing syndrome (CS) will have an ACTH-secreting pituitary tumor. When a clear-cut pituitary tumor is found on magnetic resonance imaging (MRI) in a woman with…
