ABSTRACT
Purtscher retinopathy is an occlusive microangiopathy associated with traumatic causes and usually causes visual impairment. For non-traumatic origins, it is called Purtscher-like retinopathy (PLR). A 26-year-old man reported loss of vision in his left eye after the implantation of a telescoping stent for the treatment of an intracranial carotid aneurysm. The fundus of the eye showed numerous cotton-wool spots and superficial haemorrhages. The spontaneous evolution was favourable, with almost complete resolution, except for an inferior residual scotoma. The appearance of PLR may be associated with the implantation of an endovascular stent for the treatment of intracranial aneurysms.

La retinopatía de Purtscher es una microangiopatía oclusiva asociada a causas traumáticas que suele cursar con disminución visual. Cuando la etiología no es traumática se denomina retinopatía Purtscher-like (RPL). Un varón de 26años refirió pérdida de visión en el ojo izquierdo tras el implante de un stent telescopado para el tratamiento de un aneurisma carotídeo intracraneal. El fondo de ojo mostró numerosos exudados algodonosos y hemorragias superficiales. La evolución espontánea fue favorable, con una resolución casi completa salvo por un escotoma residual inferior. La aparición de RPL se puede asociar al implante de un stent endovascular para el tratamiento de aneurismas intracraneales (Au)

The morphology of the Sella Turcica is important both as a reference in cephalometric studies and in the pituitary gland, internal carotid artery and cavernous sinus surgical boarding. The present report describes a case of partial ossification of the sella turcica walls in a dry skull of 40-year-old Brazilian individual. We analyze the morphometric characteristics of the region.
La morfología de la silla turca tiene importancia tanto como referencia en los estudios cefalomé trieos como en los abordajes quirúrgicos de la glándula hipófisis, carótida interna y seno cavernoso. En el presente reporte se describe un caso de osificación parcial de las paredes de la silla turca, en un cráneo seco de un individuo brasilero de 40 años. Se analizan las características morfométricas de la región.
