外傷を契機として発症し急性経過をとった上顎洞血瘤腫の1例

Traumatic Maxillary Hematoma

　はじめに

　上顎洞血瘤腫は比較的稀な疾患であるが，症状，画像診断では悪性腫瘍との鑑別が困難なこともあり，日常臨床を行ううえで念頭におくべき疾患といえる。今回われわれは外傷を契機として発症し，急性経過をとった上顎洞血瘤腫の1症例を経験したので，文献的考察を含め術前診断のあり方についても検討した。

Maxillary hematoma is not only difficult to dis-tinguish from malignant tumor in terms of symptoms and radiological examination, but may also lead to considerable hemorrhaging during biop-sy or surgery due to vascular proliferation in the hematoma. There are also cases where biopsy alone is not sufficient to make a definite diagnosis.

The authors experienced a case of maxillary hematoma caused by trauma with nasal bleeding and progressive anemia. Preoperative angiography and selective embolization were effective.
