Benign primary intraosseous meningioma presenting with osteolytic skull lesion and soft-tissue component is rare. CT and MR imaging of a patient with frontoparietal scalp swelling showed an osteolytic intracalvarial lesion with an extradural soft-tissue component. Following wide surgical resection, the histological examination revealed an intraosseous chordoid meningioma. The clinical and radiological findings of primary intraosseous meningioma are discussed and the relevant literature is reviewed.
表现为颅骨溶骨性病变和软组织成分的原发性骨内良性脑膜瘤很罕见。一名额顶部头皮肿胀患者的CT和MR成像显示颅内有一溶骨性病变,并伴有硬膜外软组织成分。广泛手术切除后,组织学检查显示为骨内脊索状脑膜瘤。本文讨论了原发性骨内脑膜瘤的临床和影像学表现,并对相关文献进行了综述。
