Osteolipomas of the tuber cinereum traditionally have been classified as meningeal lipomas that are located at the tuber cinereum. Examination of two cases and a review of 22 others found in the literature show that these lesions exhibit a remarkable consistency in their size and in their location between the corpora mamillaria and the pituitary stalk, and that approximately half of them contain a well-organized bone spherule with a central marrow space. These aspects differ from the features of meningeal lipomas in general; reasons are given for considering that the osteolipomas are displaced elements of the mesenchyme encompassing walls of the craniopharyngeal duct.
传统上，灰结节骨脂瘤被归类为位于灰结节的脑膜脂肪瘤。对两例病例的检查以及对文献中另外22例病例的回顾发现，这些病变在大小以及在乳头体与垂体柄之间的位置上表现出显著的一致性，并且其中约一半含有一个结构良好的骨小球，其中心有骨髓腔。这些方面与一般脑膜脂肪瘤的特征不同；给出了理由以认为骨脂瘤是围绕颅咽管壁的间充质的移位成分。
