BACKGROUND
Intracranial lipomas are extremely rare fat-containing lesions, comprising 0.1-0.5% of all primary brain tumors. Lipoma of corpus callosum, the commonest variety of all intracranial lipomas (40%-50%), is associated with varying degrees of dysgenesis of corpus callosum and generally remains asymptomatic.
CASE DESCRIPTION
In this study, we report 2 cases of pericallosal lipomas admitted with seizures and discuss the clinical and radiologic findings in light of the literature.
CONCLUSIONS
Lipomas of the corpus callosum are rare, fat-containing asymptomatic lesions, mostly associated with dysgenesis of the corpus callosum. Diagnosis accidentally occurs during diagnostic procedures in case of an encephalic disorder. Magnetic resonance imaging is the most useful modality for a differential diagnosis. Prognosis and symptoms depend on associated malformations. Surgical treatment is mostly not indicated and should be avoided.
背景
颅内脂肪瘤是极其罕见的含脂肪病变，占所有原发性脑肿瘤的0.1%-0.5%。胼胝体脂肪瘤是所有颅内脂肪瘤中最常见的类型（40%-50%），与不同程度的胼胝体发育不全相关，通常无症状。
病例描述
在本研究中，我们报告了2例因癫痫入院的胼周脂肪瘤病例，并结合文献讨论其临床和影像学表现。
结论
胼胝体脂肪瘤是罕见的、含脂肪的无症状病变，大多与胼胝体发育不全相关。在诊断脑部疾病的过程中偶然发现。磁共振成像对于鉴别诊断最为有用。预后和症状取决于相关畸形。大多数情况下不建议手术治疗，应避免手术。
