Abstract
The aneurysmal bone cyst is a nonmalignant reactive bone lesion. Developing rarely in the craniofacial region, and more commonly affecting the long bones and the spine, the lesion has variable etiopathogenic characteristics. The authors diagnosed a 33-year-old female as aneurysmal bone cyst after undergoing clinical, radiological and histological examinations. The characteristics were as followed: 1. The patient complained of pain and swelling of the right preauricular area. 2. The conventional radiograms showed a relatively well defined radiolucent lesion with partially scalloping margin. The cortical bone of the right condyle was thinned and expanded by the lesion. 3. Bone scintigraphy with ~c demonstrated ring-like or doughnut-pattern accumulation of radioactivity. 4. On Tl-weighted imaging of MRI, the lesion on the right condyle had middle signal intensity. T2-weighted MRI demonstrated multiple high signal intensities seperated by septa which had low signal intensity. Finger in balloon appearance was seen. 5. Histologically, the lesion was composed of large sinusoidal blood spaces lined by fibroblasts and histiocytes. Its fibrous stroma consisted of fibroblstic element, multinucleated giant cells, extravasated erythrocytes and focal hemosiderin pigmentation. New bone formation was also observed around larger sinusoidal spaces.
