Primary Hepatic Neuroendocrine Tumor With Ectopic Adrenocorticotropic Hormone Production

This report describes the case of a 63-year-old female with a metastatic neuroendocrine tumor (NET). Imaging studies revealed a primary hepatic NET (PHNET) originating in the porta hepatis and associated with extensive hepatic metastasis. This represents an extremely rare presentation of PHNET associated with ectopic adrenocorticotropic hormone (ACTH) production and hypercortisolism. As such, it is a unique presentation of an otherwise rare pathology and hence we believe it contributes to the literature on PHNETs by supplementing it with information on an uncommon variation of an infrequent pathology.
