ABSTRACT
Introduction Aneurysmal bone cysts (ABCs) are pseudotumoral bone lesions of unknown etiology that are also hypervascularized, benign, and locally destructive. They are rare in the base of the skull. The present case report describes a case of aneurysmal bone cyst in the sella turcica. Case Report The present study was developed at the department of neurosurgery of the Hospital Universitário Professor Alberto Antunes of the Universidade Federal de Alagoas (HUPAA-AL, in the Portuguese acronym), Maceió, state of Alagoas, Brazil, and is accompanied by a review of the literature from the PubMed database. A 17-year-old female patient with bitemporal hemianopia and intense left hemicranial headache associated with symptoms from the cranial nerves contained in the cavernous sinus. Neuroimaging evidenced a large lesion in the suprasellar region with calcification foci, sellar erosion, and extension to the cavernous sinus. The patient was submitted to a partial lesion resection and the histopathological analysis showed an aneurysmal bone cyst. Conclusion A rare case of intracranial aneurysmal bone cyst, with the important differential diagnosis from pituitary adenoma.

Los pituicitomas son tumores infrecuentes de la región selar y supraselar, originados de la neurohipófisis, que suelen ser confundidos con otros tumores al compartir características imaginológicas. Se reporta el caso de una mujer de 36 años de edad, con un pituicitoma en la región selar, que fue diagnosticado como un adenoma hipofisario debido a los hallazgos clínicos e imaginológicos preoperatorios y se realiza una revisión de la literatura.
The Pituicytomas are rare tumors of the sellar and suprasellar region originated of the neurohypophysis and are usually confused with other tumors when sharing imagining features. It is reported a case of a 36 years old woman with pituicytoma in the sellar region that was diagnosed as a pituitary adenoma due to the presurgical clinical and imaging findings and, it is revised the literature.
