Dynamic FDG PET/CT on bladder paraganglioma: A case report

Area of Science:

• Oncology
• Nuclear Medicine
• Urology

Background:

• Paraganglioma (PGL) is a rare neuroendocrine tumor (NET) originating from chromaffin cells.
• PGL often presents with nonspecific clinical manifestations, complicating early diagnosis.
• Diagnostic imaging and nuclear medicine are crucial for PGL detection and management.

Observation:

• This report describes a rare case of paraganglioma originating in the urinary bladder.
• The patient presented with an unusual onset of symptoms, initially masking the true diagnosis.
• Standard diagnostic protocols were employed, including advanced imaging techniques.

Findings:

• Positron Emission Tomography/Computed Tomography (PET/CT) demonstrated characteristic findings suggestive of paraganglioma.
• The imaging features were pivotal in differentiating the tumor from other bladder pathologies.
• Histopathological confirmation validated the PET/CT findings.

Implications:

• This case underscores the importance of considering PGL in the differential diagnosis of bladder tumors, even with atypical presentations.
• Typical PET/CT characteristics can aid in the early and accurate diagnosis of bladder paraganglioma.
• Improved diagnostic strategies for rare neuroendocrine tumors like PGL can lead to timely intervention and better patient outcomes.
