Pelvic pheochromocytoma mimicking as urinary bladder pheochromocytoma: looking beyond the obvious.
Pheochromocytomas located outside the adrenal glands are called paragangliomas. A pelvic location is rare, the most common location for a paraganglioma being the retroperitoneal space. Paragangliomas arise from neural crest cells. Pelvic pheochromocytomas may mimic urinary bladder pheochromocytomas on imaging studies. Patients may present with hypertensive crisis during micturition. We present a 26-year-old female who presented to us with accelerated hypertension with episodes of severe headache and palpitation during micturition. Based on imaging studies, she was diagnosed to have a urinary bladder pheochromocytoma. However, on exploration, the patient was found to have an extravesical pheochromocytoma arising from the left posterolateral pelvic wall, which was excised while preserving the bladder. We present this case report as pelvic pheochromocytomas can mimic bladder pheochromocytomas and are difficult to differentiate on radiological imaging and can lead to inadvertent cystectomy.
