Orbital Intraosseous Hemangioma: Report of a Case

眼眶骨內血管瘤:病例報告

摘要


原發性眼眶骨內血管瘤在臨床上並不多見。一般好發於40至50歲之病患。臨床之表徵為單獨之病灶。病患會出現病灶部位疼痛、眼球突出、眼球轉動受限、視覺受損、眼球偏移及骨腫塊等。出現臨床症狀之病例會被認為惡性病灶。我們提出一位71歲病患,該病患在7年前於左側眼眶上外側出現一無痛性,逐漸增大之腫塊。由於上眼瞼下垂及腫塊表徵,病患接受臨床評估。電腦斷層掃描發現眼眶有一多發蝕骨性骨骼病灶,形成一個個的空腔。初步被認為是眼眶骨纖維性再生不良,病患接受外科手術及病灶切除部位重建。組織病理學檢查發現該腫塊為海綿狀血管瘤。

Orbital intraosseous hemangiomas (OIHs) are rare benign lesions and few cases have been reported in the literature. They generally appear as solitary lesions in patients in the 4th or 5th decade of life. However, they can be present with pain, proptosis, restricted ocular motility, visual impairment, globe displacement or palpable bony mass. Some symptomatic cases are confused with malignancies. We report a 71-year-old man who had a 7-year history of progressive swelling in the left lateral brow area. Computed tomography showed a bony lesion with internal coarsened trabeculae and multifocal lytic areas. The lesion was thought to be fibrous dysplasia, and the patient underwent total excision of the tumor with primary reconstruction of the defect. Histopathologically, the surgical specimen showed cavernous hemangioma.
