Pheochromocytoma is a neoplasm of chromaffin tissue of the sympathetic nervous system mostly arising from the adrenal medulla. About 10% of pheochromocytomas arise from the extra-adrenal sites. Urinary bladder pheochromocytoma is a rare entity constituting less than 0.6% of all bladder neoplasms. We report one such entity in a patient with review of recent literature. ,,,
45-year-old male presented with a history of palpitation, syncope at times and tiredness after micturition for 3 years. He manifests episodic hypertension during these attacks. There is no family history of hypertension, neurofibromatosis and phaeochromocytoma. Clinical examination revealed episodic hypertension at the time of the act of micturition with normotension in between. Systemic examination including cardiovascular, respiratory, endocrinal and abdominal examination was unremarkable.
Investigations revealed haemoglobin, WBC count, blood sugar, blood urea and serum creatinine being within normal limits. The 24-hours' urinary Vanilyl Mandelic Acid (VMA) was more than 7 mg/day (Normal 2 to 7 mg/day). Ultrasound study showed a mixed echogenic mass of 6.6 x 5.3 cms arising from the bladder base. Kidneys were normal. There was no suggestion of urinary tract obstruction. Spiral Computed Tomography (CT) of the abdomen and pelvis showed a non-homogeneous mass with low density areas arising from the bladder base, the size being 6.7 x 5.4 cms with a Hounsfield value of 30 [Figure 1]. The mass was enhancing with contrast. There was no evidence of invasion. The kidneys and adrenals were normal and there was no suggestion of regional lymph node enlargement. XRay chest was normal. Cystourethroscopy revealed that the mass was arising from trigone. Surgical excision of the tumour was performed after thorough control of hypertension with alpha and beta blockers. Histopathology confirmed the tumour as chromaffin paraganglioma of the urinary bladder. Patient completed about 2 years of recurrence-free postoperative period confirmed by repeat computed tomography of urinary system being normal, urinary VMA in normal range and no abnormality in urethrocystoscopy.
Phaeochromocytoma of the urinary bladder is a rare entity constituting less than 0.5% of all the vesical neoplasms. It arises from the embryonic crest of the chromaffin cells in the sympathetic plexus of the vesical wall. Vesical phaeochromocytoma commonly presents with hypertension, haernaturia and micturitional attacks. The tumour is usually submucosal or intramural with intact vesical epithelium, the most common location being trigone. The peak incidence of presentation is usually in the 2 nd decade with female to male ratio of 3:2. UItrasonography, CT, Magnetic Resonance and Scintigraphic studies are useful noninvasive modalities for the detection and spread of the tumour.
In our patient, the symptoms of micturitional attacks with episodic hypertension, ultrasound and CT study suggestive of a tumour in the bladder with high urinary VMA were suggestive of bladder pheochromocytoma. The histopathology of the tumour confirmed the same. The patient completed about 2 years of symptom and recurrence-free period evaluated by clinical, biochemical, CT study and urethrocystoscopy.
