A falx meningioma in an 11-year-old girl had a hemangiopericytomatous and papillary pattern, but the dominant histologic feature was a pseudoglandular arrangement of the tumor cells, closely imitating an adenocarcinoma. The gland-like spaces resulted mainly from dissolution of the centers of cell nests, and to a lesser extent from the fusion of papillary processes. The tumor-recurred locally five years after surgery and maintained its pseudoglandular pattern. Recognition of the existence of a pseudoglandular variant of meningiomas can prevent the mistaken diagnosis of a metastatic adenocarcinoma and other similar tumors.
一名11岁女孩的镰旁脑膜瘤具有血管外皮细胞瘤样和乳头状结构，但主要组织学特征是肿瘤细胞呈假腺管状排列，酷似腺癌。腺样间隙主要是由细胞巢中心溶解形成，其次是由乳头突起融合形成。该肿瘤术后5年局部复发，仍保持假腺管状结构。认识到脑膜瘤存在假腺管型变体可避免误诊为转移性腺癌和其他类似肿瘤。
