Multiple Recurrent Paraganglioma in a Pediatric Patient with Germline SDH-B Mutation
Urology case reports(2017)
摘要
Magnetic Resonance Imaging (MRI) and fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET) are recognized approaches for locating paragangliomas. Recently, gallium-68 DOTA-octreotate (DOTATATE) scans have shown promise detecting neuroendocrine tumors missed by FDG-PET and MRI. 13-year-old male with SDH-B mutation presented with symptoms of paraganglioma and elevated catecholamines. MRI did not demonstrate the T2 hyper intense signal typical of paraganglioma and pheochromocytoma; FDG-PET scan did not reveal increased foci of uptake. DOTATATE scan revealed a signal consistent only with residual adrenal tissue. Resection of the right adrenal bed revealed paraganglioma. Following surgery, no further symptoms were reported and biochemical tests normalized.
