We report a 13-year-old boy with an atypical manifestation of a multilocular paraganglioma. Surgical treatment was not curative despite extirpation of a left-sided abdominal paraganglioma. After surgery, the boy experienced several hypertensive crises. Further investigations including dopamine-positron emission tomography demonstrated bilateral adrenal tumours, a further right-sided paravertebral tumour as well as bilateral cervical glomus tumours. Genetic testing revealed a germline mutation in the succinate dehydrogenase subunit D (SDHD) gene. Conclusion:The final diagnosis was familial pheochromocytoma/paraganglioma type 1 (OMIM 168000). Antihypertensive treatment was succesfull and improved the patient’s quality of life.
