Sarcoidosis mimicking metastatic carinoid on indium-111 pentetreotide scintigraphy

Carcinoid is a neuroendocrine neoplasm derived from primitive stem cells, occurring most frequently in the alimentary tract. Somatostatin-receptor scintigraphy with indium-111 pentetreotide is a sensitive and noninvasive technique for imaging carcinoid and its metastatic spread. However, nontumoral...

Sumario:Carcinoid is a neuroendocrine neoplasm derived from primitive stem cells, occurring most frequently in the alimentary tract. Somatostatin-receptor scintigraphy with indium-111 pentetreotide is a sensitive and noninvasive technique for imaging carcinoid and its metastatic spread. However, nontumoral lesions such as sarcoidosis may also express somatostatin receptors, which may present a diagnostic dilemma in some patients. We present a case of sarcoidosis mimicking metastatic carcinoid on indium-111 pentetreotide scintigraphy in a patient with a history of carcinoid and intra-abdominal metastasis.
