Unexpected Small Urinary Bladder Pheochromocytoma : A Nonspecific Presentation

Abstract EN

Objectives.

Pheochromocytoma of the urinary bladder is an extremely rare tumor that typically presents with a hypertensive crisis during micturition.

Preoperatively, it may be misdiagnosed due to nonspecific symptomatology, physical, and radiologic findings.

Method.

We report a case of unsuspected small pheochromocytoma which was incidentally found by CT scan and confirmed by the histological aspects after transurethral resection in a 63-year-old woman.

Here, we have described the clinical presentation, physical findings, laboratory investigations, and treatment provided in our case.

We have also included radiological images and histopathology slides with input from both radiologists and pathologists.

Surgical management and postoperative follow-up are discussed, as are details of previous published data.

Results.

After undergoing surgical treatment (transurethral resection), our patient is asymptomatic, with complete resolution of her pathology.

Conclusion.

Diagnosis is difficult before histopathological examination and should be considered in patients with no risk factors for usual bladder tumor.

Our purpose is to raise clinician's awareness for this condition so that they will be more likely to diagnose it.

This will facilitate prompt diagnosis and treatment and especially prevent complications due to pheochromocytoma which may be severe.
