Los pituicitomas son una entidad poco frecuente incluida en la Clasificación de los Tumores del Sistema Nervioso de la Organización Mundial de la Salud (OMS) en el año 2007. Son lesiones originadas en la neurohipófisis y han sido confundidas durante años con otros tumores hipofisarios. Presentamos el caso de una mujer de 31 años diagnosticada de una lesión supraselar en el contexto de un estudio de infertilidad debida a un hipogonadismo-hipogonadotropo con prolactina ligeramente aumentada, a la que se realizó un abordaje pterional consiguiendo su exéresis completa. Tras la cirugía aparecieron hemianopsia bitemporal, diabetes insípida y panhipopituitarismo, y los 2 últimos se corrigieron en pocas semanas. Realizamos además una revisión de sus presentaciones clínicas y radiográficas más frecuentes, así como de los tratamientos planteados en los casos publicados.

Pituicytomas are rare entities which develop in the neurohypophysis. They were included in the last World Health Organization (WHO) Classification of Central Nervous System Tumours in 2007, but for many years they have been confused with other pituitary tumours. We report the case of a 31-year-old woman who was diagnosed of a tumour in the suprasellar region during an infertility study due to hypogonadotropic hypogonadism and slight hyperprolactinemia. A standard pterional approach was performed, achieving total tumour excision. After the surgery the patient suffered bitemporal hemianopsia, diabetes insipidus and panhypopituitarism, although she recovered from the latter 2 in a few weeks. We conducted a review of the most common clinical and radiological features of this entity, as well as the treatments proposed in the literature to treat this rare tumour.
