软脑膜脂肪瘤性错构瘤Leptomeninges Hamartoma Lipomatous · 脑 · 神经系统 · NTP ntp-0397
诊断要点:在 NTP 研究中,脂瘤性错构瘤应当被诊断,并指明具体部位。
病变描述
Figure 1 展示了一种神经发育异常。该中线脑膜脂瘤性错构瘤(leptomeningeal lipomatous hamartoma)位于扣带回(cingulate gyrus)基底部,紧邻胼胝体(corpus callosum)和隔核(septal nuclei)上方。由正常白色脂肪细胞(white adipocyte)构成,处于脂瘤性错构瘤的常见部位。错构瘤的膨胀对邻近结构几乎没有压迫效应,也未伴有明显的临床神经学体征。此类错构瘤在啮齿类动物研究中不常见。不应将其与脂肪瘤(lipoma)或脂肪肉瘤(liposarcoma)混淆。

Comment:
Figure 1 depicts a neurodevelopmental anomaly. This midline leptomeningeal lipomatous hamartoma is located at the base of the cingulate gyrus, immediately above the corpus callosum and septal nuclei. Consisting of normal white adipocytes, it is in the common location for a lipomatous hamartoma. The expansion of the hamartoma has had little compressive effect on adjacent structures and was not accompanied by noticeable clinical neurological signs. This type of hamartoma is uncommon in rodent studies. It is not to be confused with a lipoma or liposarcoma.
Recommendation:
Lipomatous hamartomas should be diagnosed in NTP studies and the subsite specified.
