Bladder paraganglioma - Case report on a rare but important differential

Area of Science:

• Urology
• Oncology
• Endocrinology

Background:

• Paragangliomas are rare extra-adrenal neuroendocrine tumors.
• Bladder paragangliomas constitute less than 1% of all paragangliomas.
• They account for <0.05% of all bladder tumors.

Observation:

• This case details an incidental bladder paraganglioma discovered during routine flexible cystoscopy.
• The patient was a young female presenting with non-visible haematuria.
• The tumor mimicked other bladder pathologies.

Findings:

• The paraganglioma was incidentally found.
• Clinical presentation was subtle, with non-visible haematuria.
• Management of the incidental finding was addressed.

Implications:

• Highlights the importance of considering rare diagnoses like bladder paraganglioma.
• Underscores the role of cystoscopy in incidental tumor detection.
• Emphasizes the need for vigilance in evaluating bladder symptoms.
