Intraosseous meningiomas are a rare subtype of meningiomas representing approximately 2% of all cases. They can confound a diagnosis of other bone lesions including metastatic tumors. We present a case of a patient with prostate cancer who on staging workup was suspected to have a skull metastasis. Both bone scan and CT Head demonstrated a lesion in the right frontal calvarium. Surgical resection and pathology revealed an intraosseous meningioma. The patient was restaged as having localized prostate cancer and the was offered curative treatment for his malignancy. The case highlights the importance of obtaining tissue diagnosis in cases of radiographic isolated oligometastatic disease in patients with a known primary malignancy.
骨内脑膜瘤是脑膜瘤的一种罕见亚型，约占所有病例的2%。它们可能会混淆包括转移性肿瘤在内的其他骨病变的诊断。我们报告一例前列腺癌患者，在分期检查时怀疑有颅骨转移。骨扫描和头颅CT均显示右额骨有病变。手术切除及病理检查显示为骨内脑膜瘤。该患者重新分期为局限性前列腺癌，并接受了针对其恶性肿瘤的根治性治疗。该病例强调了在已知原发性恶性肿瘤的患者中，对于影像学检查发现的孤立性寡转移疾病进行组织诊断的重要性。
