Abstract
Herniation of meningeal and #brain tissue into the middle ear and
mastoid through a bony defect that allows meningeal and/or brain
tissue to protude into temporal bone is a rare #pahtologicalentity with
potentially life-threatening complications, requiring surgery [1,2].
While
herniation of brain tissue in middle ear usually occurs from the middle
fossa through a defect either in tegmen tympani or in the #mastoidtegmen [1,2], the etiology of this defect varies and includes chronic
otitis media with or without #cholesteatoma, and previous #otologicsurgery[1-4]. Less commonly, the osseous defect is congenital or follows skull
fracture, tumour or irradiation [2]. Nonetheless, since the introduction
of more sensitive diagnostic tools in the last few years, reports of
spontaneous or idiopathic brain #herniations have increased [2].
