Early pathologic reports of corpus callosal lipoma described a consistent relationship between the lipoma and the dorsal surface of the corpus callosum, particularly when the lipoma is not associated with corpus callosal agenesis. MR imaging, especially T1-weighted sagittal acquisitions, exquisitely demonstrated this anatomic relationship in three relatively asymptomatic patients. Therefore, in most cases, a lipoma of the corpus callosum is more accurately described as a pericallosal lipoma. In one individual, common associated findings (partial agenesis of the corpus callosum and choroid plexus lipoma) were also noted. Surgical therapy is usually not indicated because symptoms are generally not related and the anterior cerebral artery is often encased by the lipoma.
胼胝体脂肪瘤的早期病理报告描述了脂肪瘤与胼胝体背侧表面之间的一致关系，特别是当脂肪瘤与胼胝体发育不全无关时。磁共振成像，尤其是T1加权矢状位成像，在三名相对无症状的患者中精确地显示了这种解剖关系。因此，在大多数情况下，胼胝体脂肪瘤更准确地描述为胼周脂肪瘤。在一名个体中，还发现了常见的相关表现（胼胝体部分发育不全和脉络丛脂肪瘤）。通常不建议进行手术治疗，因为症状一般不相关，而且大脑前动脉常被脂肪瘤包裹。
