Abstract
Functional imaging is an important step in the diagnostic approach of patients with pheochromocytoma (PCC). Metaiodobenzylguanidine (MIBG) scintigraphy (single-photon emission computed tomography) is currently the most widely used functional imaging modality for evaluating a case of PCC. However, it has some limitations and poor sensitivity, especially in cases of malignant PCC (MPCC). Positron emission tomography (PET) scanning with gallium-68 (68Ga)-DOTA-coupled somatostatin analogs is the newer upcoming modality with some superiority over MIBG scan. We present a case of MPCC with unusual invasion and metastasis positive on DOTANOC PET scan along with relevant review of literature.
