We present the CT and MR findings of an intrasellar and suprasellar paraganglioma in a 17-year-old girl. Paragangliomas in this location are rare. The lesion had several imaging features characteristic of paragangliomas including marked enhancement after contrast and multiple vascular flow voids.

Phaeochromocytomas (PC) and paragangliomas are disorders of the sympatho-adrenomedullary system. They are chromaffin-containing neuroendocrine tumors of neural crest origin that contain catecholamine-secreting granules: they arise from either the adrenal medulla (phaeochromocytomas) or from extra-adrenal neural crest derivatives e.g. the sympathetic chain (paragangliomas). The term paragangliom...

Paragangliomas are rare neuroendocrine tumors arising from the ganglia of the sympathetic or parasympathetic nervous system. Less than 160 cases of intrapericardial or intracardiac paragangliomas have been reported in the English language peer-reviewed medical literature. Here, we report a case of intrapericardial paraganglioma, which illustrates some typical multimodality imaging features of t...

Patients with SDHD-associated head-and-neck paragangliomas (HNP) are at risk for developing pheochromocytomas for which screening has been advised. To assess clinical, biochemical, and radiological outcomes of screening in a large single-center cohort of SDHD-positive patients with HNP and to address the necessity for repetitive follow-up, we evaluated 93 patients with SDHD-associated HNP (p.As...

Extra-adrenal paragangliomas are neoplasms of the paraganglia located within the paravertebral sympathetic and parasympathetic chains. Thus paragangliomas may arise anywhere along these tracts and common sites of occurrence include abdomen, retroperitoneum, chest and mediastinum and various head and neck locations such as jugulotympanic membrane, orbit, nasopharynx, larynx, vagal body and carot...
