Intracranial midline anterior fossae ossifying fibroma invading orbits, paranasal sinuses, and right maxillary antrum

Abstract

✓ The clinical course, roentgenological findings, and operative management of a patient with an ossifying fibroma (benign osteoblastoma) of the anterior cranial fossae are described. The tumor invaded the orbits, the ethmoids, the upper nasal cavity, and the right maxillary antrum. The differential roentgenological diagnosis is discussed.

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

“…Only 14 cases of benign fibroosseous lesions involving the skull base have been reported. 8,9,11,16,[19][20][21] We describe the second case of aneurysmal bone cyst of the anterior cranial fossa floor.…”

Ossifying fibroma of the jugum sphenoidale

“…With the advent of CT imaging and its widespread use in the evaluation of head trauma, the number of reported cases has increased each year. 4 …”

“…Skull X-ray and computed tomography (CT) of the brain showed a large markedly calcified mass in the region of the pituitary fossa, associated with significant bony erosion (Figs. [1][2][3][4]. Cerebral angiography demonstrated the lesion to be markedly vascular.…”

“…1 Literature on ossifying fibromas involving the anterior cranial fossa, in particular the sphenoid bone, comprises a small number of case reports. [2][3][4][5][6] We present a case of an ossifying fibroma arising from the sphenoid bone, occupying and eroding the pituitary fossa, which mimicked a craniopharyngioma.…”

Craniofacial Resection of Ossifying Fibromas and Osteomas of the Sinuses

“…The osteomas usually appear as homogeneous, dense, or solid multiloculated masses that may ex¬ pand surrounding bony structures. 23 Therefore, patients who otherwise are in good health and who have gi¬ gantiform lesions of the frontoethmoi¬ dal region should be considered candi¬ dates for craniofacial resection and complete removal of the tumor if the lesions are causing facial deformity, pain, recurrent sinusitis, proptosis, diplopia, visual loss, or intracranial complications, including leakage of cerebrospinal fluid, pneumocephalus, or meningitis. '·24·25 This approach is consistent with the work of Edgerton et al20 in fibrous dysplasia where they stated that "surgery should be per¬ formed as soon as important function is threatened or when facial deformity becomes substantial."…”
