[Ganglioneuroma coinciding with a lumbar disk herniation]

INTRODUCTION. Ganglioneuromas or gangliomas are tumours of the sympathetic ganglia that contain cells of the neural crest, so they can appear in all body localizations. They are generally benign, more frequent between 10 and 40 years, may secrete hormones and, sometimes, Neurofibromatosis type I and other genetic disorders can be associated. OBJECTIVE. To review the scientific literature related to the topic and to present a case treated in our service. DISCUSSION. The symptoms depend on location and vasoactive secreted hormones. In spite of that, they are generally benign tumours, although sometimes they can spread out. Since laboratory and image test are of limited usefulness, the conclusive diagnosis is anatomopathologic. In symptomatic patients the best procedure is surgical removing. CONCLUSION. Ganglioneuroma and disk herniation association constitute an exceptional disorder. Its treatment implies surgery resection.
