Abstract

Neuroendocrine tumors with somatostatin receptor expression are suitable for imaging with somatostatin analogues. {sup 68}Ga-labeled peptides are useful for the diagnosis, staging and assessment of therapeutic response of these tumors. However, for a correct interpretation it is necessary to know the normal biodistribution of somatostatin receptors in the body. Asymmetric adrenal uptake may be a normal variant to cause confusion, or an accessory or ectopic spleen can lead to a false positive result. We report a case of asymmetric adrenal uptake which was correctly considered as a normal variant, but an accessory spleen caused the false impression of being a metastasis from a previously resected primary carcinoid tumor.
