Intraosseous calvarial meningiomas, defined as meningiomas confined to the skull with no epidural or subcutaneous component, are rare and usually exhibit osteoblastic activity. We present a case of a primary intraosseous meningioma in the right frontal bone that presented radiologically as a solitary lytic skull lesion and was completely excised. The lesion was benign without recurrence for 1 1/2 years. According to our review of the literature, our case is the first with documentation on computed tomography. In cases of solitary osteolytic skull lesions, meningioma should be considered even though it may not seem likely, because management will be directed to radical excision with good prognosis rather than biopsy.
颅骨内脑膜瘤定义为局限于颅骨内、无硬膜外或皮下成分的脑膜瘤，较为罕见，通常表现为成骨活性。我们报告一例右侧额骨原发性颅骨内脑膜瘤，影像学表现为孤立性溶骨性颅骨病变，已完全切除。该病变为良性，1年半未复发。根据我们对文献的回顾，我们的病例是首例有计算机断层扫描记录的病例。在孤立性溶骨性颅骨病变的病例中，即使可能性不大，也应考虑脑膜瘤，因为治疗将采用根治性切除，预后良好，而不是活检。
