Phaeochromocytoma and abdominal aneurysm: confirmation of diagnosis after aortic surgery using mIBG imaging.

Four cases of dissecting thoracic aneurysm associated with phaeochromocytoma have been reported in the World literature, of which only one survived surgery. We report what we believe to be the first case of intra-adrenal phaeochromocytoma presenting as a leaking abdominal aneurysm; which is of further interest as post-reconstruction 131-I meta-Iodobenzylguanidine (mIBG) imaging confirmed the existence of the tumour, despite equivocal urinary metanephrines.
