To report a case of extradural meningioma of a fifty eight yearsold man.


Case report.


We have experienced a case of a male that present with proptosisand progressive enlargement of the left orbit of two years ofevolution. Physical examination revealed appropriate visualacuity. Intraocular pressure was on 15mmHg in both eyes. Theleft globe displaced superolateral with significant expansionof the inferomedial orbital rim. The conjunctiva was normalin both eyes, the pupils were symmetric, with normal light reflex,the fundus was unremarkable. A soft-tissue mass of 2 x 1.8cmis located inferonasal to the globe. Computed tomography showsan extraconal mass on inferonasal region in the left orbit,anterior and outside the lacrimal sac. This lesion has reinforcementwith intravenous contrast, on a homogeneous form and expandwithout bony destruction in the ascending branch of the maxilarwithout postseptal extension. Resection of the lesion via transconjunctivalwas performed. Microscopically we can see meningothelial cellsin faeces, with whirpool zones and veins of different sizes.


The extradural meningioma is an infrequent tumor, and arisefrom ectopic meningothelial cells.Are only five similar casespreviously reported.Primary intraorbital ectopic meningiomahave an extremely low incidence and its existence has remaineda matter of controversy.
