Meningiomas are common intracranial tumors that rarely metastasize. We present a highly unusual case of a 42-year-old man with direct seeding of meningioma to the abdominal wall. The patient had a history of multiple operations for a recurrent intracranial meningioma with decompressive craniectomy and preservation of the calvarial bone flap by implantation into the subcutaneous layer of the anterior abdominal wall. Following removal of the bone flap, a new abdominal wall mass was identified, consistent with iatrogenic implantation of anaplastic meningioma.
脑膜瘤是常见的颅内肿瘤，很少发生转移。我们报告一例极为罕见的病例，一名42岁男性，脑膜瘤直接播散至腹壁。该患者有多次复发性颅内脑膜瘤手术史，行减压颅骨切除术，并通过植入前腹壁皮下层保留颅骨骨瓣。在移除骨瓣后，发现一个新的腹壁肿物，符合间变性脑膜瘤的医源性植入。
