The perioperative management of a 39-year-old Paragangllomas arise from a widely disseminated system of small sensory and neurosecretory organs that develops in fetal life and subsequently decreases in size. t Phaeochromocytomas are classical examples of endocrinologically active chromaffin paragangliomas. Typical nonchromaffin paragangliomas (NCPG) are tumours of the carotid body and glomus jugulare. A NCPG is usually eudocrinologically inactive, but there are rare cases, such as the one described in this report, of a NCPG producing and releasing catecholamines. 2'3 Urinary bladder paragangliomas are uncommon,I have a familial tendency 4 and a mean age of presentation of 38 years. When these paragangliomas stain chromaffinpositive and are endocrinologically active, they have been called bladder phaeochromocytomas. Patients with these "phaeochromocytomas" may present with a classical triad s of haematuria, hypertension and micturitional attacks typical of a "phaeoehromocytoma syndrome ''6 (headaches, tremulousness, anxiousness and a pounding sensation). Fortunately, bladder phaeochromocytomas are rare, representing only 0.06 per cent of bladder tumours. 2 Seven to 20 per cent of these tumours are malignant 1,5 and can be detected by increased serum dopa and dopamine levels]In this report, we describe the anaesthetic management of a patient who underwent incomplete resection of a malignant, highly functional NCPG of the bladder. This tumour, which to the best of our knowledge has never been reported before, is difficult to distinguish from a phaeochromocytoma. The case was complicated by atypical presentation, substantial release of catecholamines from the tumour, difficult preoperative control of hypertension and complex surgical resection.
Case reportA 39-year-old, 61 kg, white male was admitted to the urology service with weight loss, nausea, vomiting, malaise, headaches, hypertension, bladder mass, right flank pain and right hydronephrosis.
