ABSTRACT
Es bien conocido que la cirugía bariátrica no está exenta de complicaciones, en especial las técnicas de hipoabsorción. Sin embargo, en la práctica clínica la pérdida de visión por déficit de vitamina A como complicación nutricional de este tipo de cirugía es poco habitual. Presentamos el caso de una paciente de 56 años con xeroftalmía bilateral con perforación corneal del ojo izquierdo y disminución de la agudeza visual bilateral después de ser sometida a cirugía bariátrica (derivación biliopancreática tipo Scopinaro) por obesidad mórbida. A pesar del tratamiento sustitutivo con altas dosis de vitamina A, la pérdida de visión del ojo izquierdo es prácticamente total (AU)
It is well known the bariatric surgery is not without complications, particularly malabsorptive techniques. However, loss of vision due to vitamin A deficiency as a nutritional complication of this type of surgery is rare in clinical practice. We report the case of a 56-year-old woman with bilateral xerophthalmia, left corneal perforation and reduced bilateral visual acuity following bariatric surgery (Scopinaro type biliopancreatic diversion) for morbid obesity. Despite treatment with very high doses of vitamin A supplements, the loss of vision in the left eye was practically complete (AU)

Bone sarcoidosis of the skull is an infrequent presentation of sarcoidosis. We describe a 51-year-old man who consulted due to inflammatory-appearing nodulation in the right supraorbital region. Images showed a solitary osteolytic lesion extending to soft tissues with increased scintigraphic uptake. The anatomopathological study revealed the presence of non-caseating epithelioid granulomas, compatible with sarcoidosis. Steroid treatment led to a marked remission of the lesion, without evidence of relapse during a follow-up period of 1 year. The literature dealing with skull sarcoidosis is reviewed.
