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. ## 英文原文 · Recommendation Lipomatous hamartomas should be diagnosed in NTP studies and the subsite specified. ## 配图 - https://www.labsmart.cn/ntp-atlas-images/ntp_0575.jpg 整理:北京天融慧通科技有限责任公司(LabSmart)| https://www.labsmart.cn
