To present a patient with giant cell tumor (GCT) of the orbit by changing behavior from an intraorbital mass to an intraosseous tumor.
A 16-year-old boy presented with pain, swelling, erythematous of the left upper and lower eyelids, proptosis, and diplopia. Ophthalmic examination revealed chemosis, conjunctival injection, limited elevation, depression as well as abduction in the left eye.
Multislice computed tomography scan (CT scan) of the orbit and paranasal sinuses showed a hyperdense, oval, extraconal mass with bone erosion. Magnetic resonance imaging of the orbit showed an inferior lateral isointense, oval, extraconal mass that had indented the globe. The patient underwent superior lateral orbitotomy, and the orbital mass was excised. Two months later, the patient developed proptosis, severe chemosis, and eyelid erythema in the same eye. CT scan showed an intraosseous mass in the lateral wall of the orbit that had pushed the globe anteromedially. Intraosseous tumor was resected, and the lateral orbital wall was drilled during the second surgery. GCT was diagnosed based on pathological survey.
Following the resection of the orbital GCT, the tumor behavior may change to an intraosseous lesion.
报告1例眼眶骨巨细胞瘤（GCT），其表现从眶内肿块转变为骨内肿瘤。
一名16岁男孩出现左上、下眼睑疼痛、肿胀、红斑、眼球突出和复视。眼科检查发现左眼结膜水肿、结膜充血、上抬受限、下转受限以及外展受限。
眼眶和鼻窦的多层计算机断层扫描（CT扫描）显示一个高密度椭圆形眶锥外肿块伴有骨质侵蚀。眼眶磁共振成像显示一个位于下外侧等信号的椭圆形眶锥外肿块，该肿块使眼球受压。患者接受了眶上外侧切开术，切除了眼眶肿块。两个月后，患者同一只眼睛再次出现眼球突出、严重结膜水肿和眼睑红斑。CT扫描显示眼眶外侧壁有一个骨内肿块，将眼球向前内侧推移。第二次手术切除了骨内肿瘤，并对眼眶外侧壁进行了钻孔。根据病理检查诊断为骨巨细胞瘤。
眼眶骨巨细胞瘤切除后，肿瘤表现可能转变为骨内病变。
