Paraganglioma presenting as a vascular malformation: case report.

Abstract

Paragangliomas are rare tumours that arise from extra-adrenal chromaffin cells or neuroectodermal chemoreceptor. They are high vascularised and can be functional, secreting catecholamines and other peptides. They occur anywhere from the skull base to the pelvic floor, within the paraganglion system. We present a case of paraganglioma with unusual location, atypical presentation and interesting vascular anatomy.
