Paraganglioma of the Ponytail in One Case

Abstract

Paraganglioma is a rare neuroendocrine tumor composed of paraganglionar cells, much vascularized, usually benign. It is located mainly in the medullo-adrenal part of the superior gland, the carotid glomus and the jugular glomus. Paraganglioma of the ponytail is very rare. The first case was reported in 1972, the clinical signs are not specific. The magnetic resonance image (MRI) is the choice test. It appears in isosignal in sp T1 and in isosignal in T2, containing several sinuous vessels which represent a diagnostic value of this tumor. This case of the ponytail paraganglioma has been confirmed by MRI and immunohistochemistry.
