title: Functioning middle mediastinal paraganglioma (phaeochromocytoma) associated with intercarotid paragangliomas.
abstract: In three patients with phaeochromocytomas, computed tomography or iodobenzylguanidine scanning gave misleading or negative results. These patients were found to have a functioning middle mediastinal paraganglioma in association with one or two intercarotid paragangliomas. The possibility of this association should be considered in patients with functioning extra-adrenal paragangliomas.
