Vernet O Ducrey N Déruaz JP de Tribolet N 1993 Giant cell tumors of the skull are very rare and usually occur in the sphenoid bone. The authors report the case of a 10-year-old boy with such a tumor involving exclusively the roof of the left orbit. He presented essentially with edema of the left superior eyelid and diplopia. Computed tomographic examination and magnetic resonance imaging delineated the lesion, which was radically removed via a left fronto-orbital craniotomy. Some aspects of this rare neoplasm are reviewed. https://sonar.ch/global/documents/29951 eng info:eu-repo/semantics/altIdentifier/doi/10.1227/00006123-199305000-00022 info:eu-repo/semantics/altIdentifier/pmid/8492864 Neurosurgery. - 1993 Cerebral Angiography Child Craniotomy Diagnosis, Differential Giant Cell Tumors Humans Male Orbit Orbital Neoplasms Tomography, X-Ray Computed Giant cell tumor of the orbit. http://purl.org/coar/resource_type/c_6501
