We present the case of a thirty five year old salesman in whom microscopic haematuria was detected during a routine employment medical. History and physical examination were unremarkable. A renal ultrasound initiated by the urology service revealed an upper abdominal mass. CT abdomen confirmed a 5x6cm lesion distinct from the right kidney and adrenal gland. A CT-guided biopsy precipitated a hypotensive crisis (90/60mmHg) and hypoglycaemia (blood glucose 2.3mmol/l). 24-hr urinary collections showed raised noradrenaline levels (579, 586, 573 nmols/24hrs) normal adrenaline levels. An I131MIBG scan confirmed the previously identified mid-abdominal area plus unsuspected high activity in the upper pharyngeal area with bony metastases in the anterior arch of C-2 vertebra on MRI. The primary lesion was excised with ongoing MIBG therapy to the metastatic deposit. Phaechromocytomas are uncommon catecholamine-secreting tumours. They may present atypically in diverse locations with 95% intra-abdominal. We believe a high index of suspicion combined with a and b -blockade is essential prior to invasive procedure of any intra-abdominal mass of unknown aetiology. Failure to suspect, especially nonendocrine services, may result in a fatality with medicolegal implications.
