Pheochromocytoma and multifocal functioning paraganglioma in a 9-year-old boy with von Hippel-Lindau disease

We report the case of a 9-year-old boy presenting with multifocal paraganglioma partially involving the right suprarenal gland, abdominal paraganglia, and the left para-aortal retropleural region. Von Hippel-Lindau disease (VHL) was diagnosed exclusively by VHL-gene analysis. Other clinical signs of VHL were lacking. After a complaint-free period of 7 months the boy developed a metachronous paraganglioma adjacent to the opposite adrenal gland. Patients with VHL disease should undergo adrenal-sparing surgery.
