ABSTRACT

Polyarteritis nodosa (PAN) is a rare systemic necrotising medium vessel vasculitis. The hallmark of this condition is aneurysms which are seen in visceral arteries. Aneurysms of extracranial neck and head vessels are rare. We describe a case of PAN who had such aneurysms together with characteristic aneurysms in the mesenteric circulation.

ABSTRACT

Los angiofibromas juveniles nasofaríngeos son los tumores nasofaríngeos benignos más frecuentes. Se presentan predominantemente en varones púberes. Los síntomas más frecuentes son obstrucción nasal y epistaxis recurrentes. A pesar de que su comportamiento biológico es benigno, tiende a crecer destruyendo las estructuras óseas vecinas a la nasofaringe hasta extenderse a la base del cráneo. Recurren con una frecuencia que va del 35 al 57 por ciento después de la extirpación quirúrgica incompleta. El diagnóstico diferencial debe hacerse con hemangiopericitoma, tumor fibroso solitario, hemangiomas, schwannoma e histiocitoma fibroso
