Abstract:
Gallium‐68 ( 68 Ga )‐labelled somatostatin analogue imaging by positron emission tomography ( PET ) is increasingly replacing single photon (such as 111 I n‐labelled octreotide) imaging in the detection and staging of carcinoid and other neuroendocrine tumours. Among other tissues, pituitary uptake of 1,4,7,10‐tetraazacyclododecane‐1,4,7,10‐tetraacetic acid‐octreotate ( DOTA‐TATE ) and other somatostatin analogues is physiological. DOTA‐TATE also accumulates in meningiomas, which have a high density of somatostatin receptor expression. The combination of pituitary and skull base meningioma uptake results in a characteristic ‘double hot spot’ appearance, which indicates the presence of a meningioma. This is a case of a middle‐aged woman who underwent 68 Ga ‐ DOTA‐TATE PET for confirmation and staging of clinically suspected carcinoid tumour, in whom a skull base meningioma was incidentally discovered. With the increasing use of PET in the management of neuroendocrine tumours – and the not infrequent occurrence of meningiomas – the appearance of meningiomas on somatostatin analogue imaging should be one with which reporting clinicians are familiar.
