ABSTRACT
Carcinoid syndrome arises from neuroendocrine tumors, characterized by the presence of neurosecretory granules. The diagnosis of carcinoid syndrome involves biochemical testing and various imaging techniques. We report the case of a 62-year-old man with Parkinson's Disease who was found to have new-onset cirrhosis and multiple hepatic lesions with necrosis on CT imaging. These findings were concerning for metastatic malignancy of unknown primary origin. Subsequent MRI characterization of the liver lesions indicated hepatocellular carcinoma as the most likely diagnosis. However, a transthoracic echocardiogram, performed for anasarca and dyspnea on exertion, revealed a thickened tricuspid leaflet, highly suspicious for carcinoid valvulitis. A biopsy of one of the hepatic lesions was consistent with neuroendocrine tumor, confirming the diagnosis of carcinoid syndrome. This case highlights the limitations of diagnostic imaging approaches in distinguishing hepatocellular carcinoma from neuroendocrine tumors.
