Recurrent Meningioma With Metastasis to the Skin Incision-Case Report-

概要

論文の詳細を見る
A 70-year-old woman presented with meningioma with metastasis to the skin incision. Neuroimaging demonstrated a tumor of the falx extending to the frontal bone. The tumor was grossly totally resected through a coronal skin incision. The histological diagnosis was meningotheliomatous meningioma. The tumor recurred in the ethmoid sinus 2 years later, and was resected through the transfacial approach. One year later, the tumor recurred in the ethmoid sinus and orbit, and was resected through the transcranial approach. Six months later, she noticed an isolated small mass under the skin incision, distant from a further recurrence of the tumor. Both tumors were resected. The histological diagnosis was atypical meningioma. Resection of atypical meningioma carries the risk of iatrogenic metastasis. Surgeons should wash out the operative field carefully and change surgical tools frequently.
