The CT angiogram shows a paraganglioma, a rare neuroendocrine tumour arising from the extra-adrenal autonomic paraganglia. This tumour was found in a 44-year-old man presenting with severe arterial hypertension that proved refractory to antihypertensive therapy. As was the case here, paragangliomas can be hormonally active and secrete catecholamines. Preoperative blood pressure control was achieved with α- and β-adrenergic blockade and the patient proceeded to surgical excision.
