Abstract:Os meningiomas extracranianos e extraespinais primários são raros, tendo sido descritos, até 1973, cerca de 50 casos :i . Algumas das localizações mais comuns são a órbita, o nervo óptico, a pele, a cavidade nasal, o ouvido médio e o pescoço s . 5 . O meningioma intraósseo primário da calota craniana distingue-se do meningioma intraósseo secundário por não ser extensão de tumor intracraniano e pela ausência de comprometimento da dura-mater. Azar-Kia & col. Ao exame clínico, nada foi observado de anormal, além … Show more

A case of calvarial meningeoma in a 42 year old female is reported. Arising from the inner table of the skull, it projected a extracranial mass without neurological simptomatology. The surgical procedure give good results. Some aspects of the literature and radiologics finds are commented. The infrequency of this pathology is resulted.

Primary intraosseous meningioma of the skull is an uncommon lesion often confused preoperatively with a primary bone tumor of the skull. The case of an intraosseous meningioma without dural connection or association with a cranial suture is reported that was radiographically diagnosed as Paget's disease and initially treated conservatively. Persistent headache prompted a biopsy, yielding a benign, heavily ossified, and psammomatous meningioma. The lesion was treated with wide surgical excision and acrylic cranioplasty. Subsequent review of the literature has revealed 35 additional cases of purely intraosseous meningioma. An analysis of these 36 cases demonstrates a mean patient age at diagnosis of 45 years and a 2:1 female preponderance, with the majority of lesions associated with cranial sutures. Sixty-four percent of the lesions were hyperostotic on plain skull x-ray films; the rest were osteolytic or a mixture of both. There was no relationship to prior trauma. The treatment of choice is wide surgical resection followed by cranial reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
