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

Abstract

A 19-year-old male patient presented with a midline facial, nose, and forehead hard and bony swelling associated with hypertelorism. Neuroimaging revealed a massive tumor involving the anterior cranial fossa floor, which had occupied and enlarged all paranasal air sinuses, and displaced the orbits outwards and the frontal lobes of the brain superiorly. A basal transcranial route was used for radical resection of the massive and vascular tumor. Histological examination confirmed an aneurysmal bone cyst. Such tumors only rarely involve the cranial bones or paranasal air sinuses.

Aneurysmal Bone Cyst of the Orbit : A Case Report with Literature Review

“…In the cranium, the vault is the frequent site for ABC, but the sphenoid, ethmoid, and orbit are rarely involved. Cranial ABC causes destruction of both inner and outer table of the skull, resulting in painful or painless mass by external expansion and neurological symptoms by compressing the brain or cranial nerve4,11,16,18).…”

Aneurysmal Bone Cyst of the Petrous Bone: Case Presentation and Review of the Literature

“…The lesions usually impart intense contrast enhancement after intravenous gadolinium injection [6,7]. Angiography often shows abnormal circulation with patchy areas of delayed venous phase contrast and occasional arteriovenous shunts [36]. Interestingly, unlike ABC in the skeleton, lesions in the skull are less likely to demonstrate pathologic circulation [28].…”

“…It has been noted that recurrence of ABC of the calvaria is rare, which is unlike ABC in other locations [5]. Nadkarni et al [36] noted that the recurrence rate of an ABC is 59% after simple curettage, and furthermore, the use of cryosurgery after curettage is associated with a lower recurrence rate. In the past, radiation therapy has not been a preferred treatment option because of the potential for malignant transformation of the lesions.…”

Giant Aneurysmal Bone Cyst of the Anterior Cranial Fossa and Paranasal Sinuses Presenting in Pregnancy: Case Report and Literature Review

“… 2 Lesions involving the skull are rare, comprising only 3 to 6% of all ABCs. 3 ABCs have been reported to involve both the neurocranium (ethmoidal and/or sphenoidal, 10 11 12 13 14 15 16 17 18 temporal, 19 20 21 22 23 24 25 26 27 28 29 30 occipital, 21 31 32 33 34 35 parietal, 36 37 frontal, 12 38 39 40 41 ) and viscerocranium (mandible, 42 maxilla, 43 and zygoma 44 ).…”

“…Lesions involving the skull base are more likely to present with focal neurologic deficits. These can include anosmia, 10 12 visual deficits, 12 13 17 46 facial numbness, 30 ocular motility deficits and diplopia, 18 40 hearing loss, 19 23 30 facial weakness, 23 24 30 jugular foramen syndrome, 47 and ataxia. 33 ABCs may also present with symptoms and signs of elevated intracranial pressure, 21 23 48 spontaneous intracranial hemorrhage, 20 49 seizure, 29 50 obstructive hydrocephalus, 34 proptosis, 10 14 16 17 40 epistaxis and nasal obstruction, 11 12 15 17 otalgia, 30 otitis media, 24 and ear mass.…”
