Purpose:
To evaluate the efficacy of multi-detector row CT (MDCT) findings in the diagnosis of fibrous dysplasia (FD) in orbital bone.
Methods:
The MDCT manifestations of 18 cases of FD in orbital bone (6 cases from the 458th hospital of PLA, 12 cases from the Zhongshan ophthalmic center of Sun Yat-Sen university) collected from April 2002 to August 2009 were reviewed. Six cases were confirmed by biopsy, 5 cases were confirmed by operation and postoperative pathology, the remaining 6 cases were confirmed based on typical CT findings.
Results:
FD in orbital bone could be originated from monostotic single lesion (5 cases), monostotic multiple lesions (1 cases) or polyostotic multiple lesions (12 cases). Twelve lesions were originated in the frontal bone, 5 lesions in the sphenoid, 2 lesions in the ethmoid, 7 lesions in the temporal bone.
Conclusions:
MDCT is very important in the diagnosis and treatment strategy of FD in orbital bone correctly. It help identify the location and extension of the lesions based on the axial plane, coronal plane and sagittal plane view.
