Resumen

Las malformaciones cavernosas de la región pineal son raras, con solamente 21 casos publicados hasta el momento en la literatura. A pesar de la dificultad de su diagnóstico debido a su extrema rareza, la presencia de esta lesión puede ser sospechada basándonos en sus características radiológicas.

Presentamos el caso de una paciente de 57 años de edad, con un cuadro clínico de instauración aguda de desorientación, somnolencia y diplopia. La TC cerebral mostró una hemorragia aguda en la región pineal e hidrocefalia triventricular asociada y la RM cerebral fue sugestiva de que se tratase de una malformación cavernosa. La paciente fue operada con escisión total de la lesión y el estudio histológico confirmó el diagnóstico de angioma cavernoso. Concluimos que la cirugía para extracción total de la lesión es el tratamiento de elección cuando, basados en la imagen, sospechamos un angioma cavernoso de la región pineal.

Summary

Cavernous malformations rarely occur in the pineal region with only 21 reported to date. Although its diagnosis is not easy because of the extreme rareness of this condition, the presence of this lesion can be suspected based on its typical radiological findings.

We report the case of a 57-year-old woman presented with desorientation, somnolence and diplopy. The CT-scan showed an acute hemorrhage in the pineal region and triventricular hydrocephalus. An MRI suggested a cavernous malformation. The patient was operated with total en-bloc removal of the lesion. We conclude that surgical exploration and total resection is the treatment of choice when the diagnosis of cavernous angioma is suspected of the basis of neuroimaging.
