“…Other sites involved are the urethra (12.7%), pelvis (4.9%) and ureter (3.2%) 3. The first case of a paraganglioma of the bladder was described by Fernandez et al 4. Bladder paragangliomas account for less than 0.06% of all urinary bladder tumours and 6% of all extra-adrenal phaeochromocytomas 5.…”

Paraganglioma of the bladder is a rare tumour accounting for less than 0.06% of all urinary bladder tumours and has varied presentations. It may present with clinical symptoms of phaeochromocytoma, may be non-functioning and asymptomatic or may present with haematuria. Hence, paragangliomas are occasionally misdiagnosed, and this results in unanticipated intraoperative hypertensive crisis. We present the case of a 44-year-old woman with urinary bladder paraganglioma who presented with young onset hypertension, recurrent micturition syncope with prior history of coronary artery disease and stroke. She was stabilised preoperatively with alpha blocking agents and subsequently underwent successful transurethral resection of the same.

“…Since first described in 1953, a review of the contemporary literature demonstrates the mean patient age of reported cases of PUB is 43.3 years, with an age range of 11-84 years, and a male:female ratio of 1.07:1 [2,5]. The most common presenting symptoms of PUB were found to be hypertension, micturition attacks, headache, hema-turia, and syncope [2].…”

“…Pheochromocytoma is a neuroendocrinal tumor that arises from the chromaffin tissue of the adrenal medulla and sympathetic ganglion (1) . Pheochromocytomas can occur anywhere from the skull to the bladder, and around 10% arise from extra -adrenal organs, where they are known as paragangliomas (2) . Bladder pheochromocytoma arises from the chromaffin tissue of the sympathetic nervous system and is associated with the bladder wall (3) .…”

Bladder pheochromocytoma, as a rare bladder tumor, which originated from the chromaffin tissue of the sympathetic nervous system. It is difficult to distinguish from other non-epithelial tumors on imaging. This study reported a 31-year-old female, whose physical examination revealed a bladder mass for 50 days. The patient's main clinical symptoms included sudden headache, dizziness, increased blood pressure, and chest palpitations after intermittent micturition. However, laboratory tests showed that the 24-hour urine catecholamine levels (norepinephrine, vanillylmandelic acid [VMA] and metanephrine) were normal. Magnetic resonance imaging (MRI) showed a mass in the posterior bladder wall, the typical performance is"light-bulb" bright lesion on T2-weighted imaging. The mass was surgically excised, and histopathological examination revealed that it was a pheochromocytoma. During the first 3-month of postoperative follow-up, the patient's symptoms gradually subsided. To our knowledge, this is the first case reporting on the use of MRI imaging and specific image features of this rare bladder pheochromocytoma. Due to the better soft tissue resolution and multi-parameter on MRI, changes in the size and internal signal of the lesion can be clearly displayed. Thus, MRI is an indispensable tool in tumor diagnosis and prognosis assessment.
