OBJECTIVE:
To study the clinical manifestation, radiograph features, pathology, diagnosis and treatment of fibrous dysplasia in cranial bone.
METHOD:
A case of fibrous dysplasia involving sphenoid and occipital is reported and literature were reviewed.
RESULT:
The most common complaint were headache, proptosis, diplopia, or visual changes. Distinguishing features of fibrous dysplasia on CT include "ground-glass" appearance, bone fiber anisotrophy, aneurysmal bone cyst formation and thickness of the cranial cortices. Fibrous dysplasia could be exactly diagnosed by pathology. Computed tomography was also a choice for diagnosis.
CONCLUSION
Fibrous dysplasia involving the cranial bone can present in myriad ways. Modern imaging modalities and histopathologic analysis is required to make accurate diagnosis. Surgery, particularly in a challenging region such as sphenoid and occipital bone, should preserve the existing function for the patients with functional impairment or a cosmetic deformity.

OBJECTIVE:
To show imaging findings of inferior orbital fissure (IOF) and groove (IOG) on axial CT scans and to discover their anatomic variations, so as to avoid misdiagnosing them as orbital fracture.
METHODS:
25 normal skull were used to investigate the configurations of IOF and IOG. Five skulls were performed axial CT scans. 20 normal orbital axial scans were studied as well. MPR and RT-3D reconstructions were used in this study.
RESULTS:
Skulls scans and normal orbital images on axial CT showed three sorts of findings: (1) single bony dehiscence between lateral and inferior walls; (2) first type of double bony dehiscence between lateral and inferior walls, among the dehiscence interposing a small bone. The long axis of the small bone was parallel to orbital wall; (3) second type of double bony dehiscence between lateral and inferior walls, but the long axis of the small bone was in anteroposterior direction. Anatomy and variation of three sorts of CT findings were corresponded respectively to: (1) a baseball club-shaped IOF; (2) a "V"-shaped IOF, that is composed of both of lateral and internal ramus, lateral ramus situates between the zygoma and the lateral portion of greater wing of sphenoid, and internal ramus between the maxilla and the internal portion of greater wing of sphenoid, both rami intercross caudally and open upwards in a "V"-shaped configuration; (3) a deep IOG with a protuberant lateral wall.
CONCLUSION
Familiarity of imaging features on the axial CT scans and understanding of their anatomy of IOF and IOG would be helpful for avoiding misdiagnosis of orbital fracture.
