Familial Tuberculum Sellae Meningiomas
Objectives:
The aim of this study was to study and explore the genetic mechanism of familial meningiomas through 3 cases of familial tuberculum sellae meningioma.
Methods:
A retrospective analysis of clinical data of 3 cases of familial tuberculum sellae meningioma patients, and the pathological results of types and immunohistochemical results of the 3 patients were compare.
Reults:
Three cases of postoperative pathology were meningiomas (mixed type), immunohistochemical examination showed that Vimentin, epithelial membrain antigen , and Ki67 were positive.
Conclusions:
The occurrence of meningiomas is associated with ≥1 chromosomal deletions, and the absence of certain tumor suppressor genes may be the genetic basis for the familial growth of meningiomas.
Insights
Familial meningiomas may result from chromosomal deletions and the loss of tumor suppressor genes. This study explored the genetic mechanisms behind these rare brain tumors in three cases.
Area of Science:
- Neuro-oncology
- Genetics
- Pathology
Background:
- Familial meningiomas are rare brain tumors with an unclear genetic basis.
- Tuberculum sellae meningiomas represent a specific subtype, and familial occurrence warrants further investigation into underlying genetic mechanisms.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
