With an incidence rate of 15-20%, meningiomas are one of the most common brain tumors among benign intracranial tumors. They are distributed as follows in intracranial localizations: parasagittal and falx (25%), convexity (18%), sphenoid wing (18%), parasellar (12%), posterior fossa (10%), intraventricular (2%), intraorbital (1%), and extracranial (1%). The most common extradural localizations are the paranasal sinuses, nasal cavity, skin, neck, glands, and intraosseous space. Intradiploic meningiomas are generally localized in the frontoparietal and orbital regions. Due to their low incidence and lack of adequate preoperative diagnostic testing, intradiploic meningiomas are generally mistaken for primary calvarial bone tumors and en plaque meningiomas. Our case was discussed here with literature findings since primary intradiploic meningioma is uncommon and poses diagnostic challenges.
脑膜瘤的发病率为15%-20%,是颅内良性肿瘤中最常见的脑肿瘤之一。它们在颅内的分布如下:矢状窦旁和大脑镰(25%)、脑凸面(18%)、蝶骨嵴(18%)、鞍旁(12%)、后颅窝(10%)、脑室内(2%)、眶内(1%)和颅外(1%)。最常见的硬膜外部位是鼻窦、鼻腔、皮肤、颈部、腺体和骨内间隙。板障内脑膜瘤通常位于额顶叶和眶区。由于其发病率低且术前缺乏充分的诊断检查,板障内脑膜瘤通常被误诊为原发性颅骨肿瘤和斑块状脑膜瘤。由于原发性板障内脑膜瘤并不常见且存在诊断挑战,我们在此结合文献研究结果对该病例进行讨论。
