“…12 Magnetic resonance imaging offers excellent definition of soft-tissue and ocular involvement and allows assessment of adjacent neurovascular structures. 5,19 Of particular usefulness, MR imaging demonstrates cystic change (or mucoceles) as evident by very high signal from the cystic component seen on T 2 -weighted images and very low signal from bone sclerosis observed on T 2 -weighted images. 12 Enhancement of pathological tissue is commonly observed on MR imaging but is more difficult to discern on CT scanning.…”

Fibrous dysplasia is a benign but slowly progressive disorder of bone in which normal cancellous bone is replaced by immature woven bone and fibrous tissue. Significant deformity and both acute and chronic visual impairment can result. A contemporary understanding of fibrous dysplasia, emphasizing the origins of visual impairment, indications for decompressive surgery, and the techniques for correction of the cosmetic deformity are presented. In their experience and review of the literature, the authors found the most frequent clinical presentations to be exophthalmos, displacement of the globe, abnormalities of extraocular motility, cosmetic deformity, and visual impairment. Although traditionally the cause of visual impairment has been ascribed to impingement of the optic canal on the optic nerve, the authors' experience is that the most common cause of visual loss is cystic degeneration of the tumor, particularly with those involving the anterior clinoid process. Exophthalmos and optic canal stenosis are less common causes of visual impairment. Indications for surgical intervention include acute and/or serially radiographically documented and relentless visual impairment and significant cosmetic deformity. Individualized management strategies are also discussed.

“…1,4,7,13,20) MR imaging can be useful for assessing the cellular components that can indicate malignancy. 2,10,12) Sudden, rapid disappearance of bone structures and cortical destruction after pathologic fracture suggest malignant change in fibrous dysplasia. Furthermore, [ 11 C]Met PET may reveal increasing accumulation in cases of malignant transformation of fibrous dysplasia.…”

“…Recently, magnetic resonance (MR) imaging 2,10,12) as well as radiography and computed tomography (CT) 6) have been used to identify fibrous dysplasia, which must be differentiated from other types of tumors. Bone scintigraphy with technetium-99m-hydroxymethylene diphosphonate ( 99m Tc-HMDP) has revealed increased bone mineral turnover in fibrous dysplasia.…”

Two cases of fibrous dysplasia in the skull base bone appeared hypointense on T 1 -and T 2 -weighted magnetic resonance imaging, with accumulation of [ 11 C]methyl-L-methionine ([ 11 C]Met) on positron emission tomography (PET). Fibrous dysplasia is a benign bone disorder which is identified by its distinctive radiography, computed tomography, and bone scintigraphy findings. [ 11 C]Met PET may indicate the presence of viable tumor-like cells in fibrous dysplasia.
