Aneurysmal Bone Cyst as an Intracranial Space-Occupying Lesion

Massive Aneurysmal Bone Cyst of the Anterior Cranial Fossa Floor. Case Report.

“…15) Aneurysmal bone cysts have occurred at various locations in the calvarium and the skull base, including the occipital bone, 14,15,17) the frontal bone, 4,7) the temporal bone, 6) and the parietal bone. 5) The previous case of aneurysmal bone cyst involved the nasal cavity, sphenoid bone, and skull base.…”

Le kyste osseux anévrismal de l’orbite

“…isolément dans 8 cas, parfois associé à une extension ethmoïdale [22,27]-Les autres localisations, elhmoïdalc [26], sphéno-maxillo-ethmoï-dalc [30] ou sphéno-maxillo-temporale [27|, sont rares. Il convient de toujours redouter l'extension intracrânienne de la lésion, dé celée dans 4 cas sur 13: des signes ncuroophthalmologiques sont alors souvent re trouvés, associés [24,27] [29] qui a récidivé 1 an après. Ce traitement chirurgical doit certainement être recommandé dans les formes localisées à l'os frontal.…”

Intracranial Intradural Aneurysmal Bone Cyst: A Unique Case

“…Trauma, both direct and indirect, as an etiological factor can be omitted in view of the deep location of the tumor. In the report by Costantini et al [9], proliferation of the internal periosteum through the dural erosion has been postulated for the intracranial location of the cyst. No dural elements were found on histology.…”

“…Costantini et al [9] described a patient with an extracerebral intradural ABC occupying the anterior cranial fossa that had a complete intracranial development. A detailed study of the orbital roof during surgery showed an area of implantation about 1 cm in diameter.…”
