ABSTRACT
To determine the clinicopathological and imaging features in 18F-fluoro-2-deoxyglucose (18F-FDG) positron emission tomography and computed tomography (PET/CT) for paraganglioma of testis, and to increase the diagnostic accuracy.
Methods:
A case of paraganglioma of testis with multiple lymph node and lung metastasis were reported. PET/CT and pathological findings in the case were retrospectively analyzed.Results:
The patient presented with high blood pressure, high level of catecholamine, and urinary vanillylmandelic acid. The patient underwent 18F-FDG PET/CT, which showed the features including the right testis nodule with a star lesion nearby, the right spermatic cord, the lymphadenopathy of bilateral inguinal and retroperitoneum, the posterior basal segment of right lung nodule, and a lot of brown adipose tissues (BAT) in the whole body with intense FDG uptake. 18F-FDG PET/CT showed that the intense FDG uptake of the BAT disappeared after the excision of the right testis and metastasis of paraganglioma.Conclusion:
PET/CT shows great value in localization diagnose, clinical staging and curative evaluation. PET/CT plays a helpful role in revealing the BAT with 18F-DG avidity in the patients with paraganglioma with elevated blood pressure, high level catecholamine, and urinary vanillylmandelic acid.
