不同于许旺氏细胞瘤，脊膜瘤主要位于上段和中段胸椎水平，但是在前后方向有相似的分布。

Meningiomas are predominately located in the upper and mid- thoracic areas, different from schwannomas, but are in a similar distribution in the anterior-posterior plane.

网状细胞染色考虑许旺氏细胞瘤可能性大于脑膜瘤或室管膜瘤，超过50%的许旺氏细胞瘤在网状细胞染色时可见胞质淡染。

Reticulin staining (c) is more consistent with schwannoma than either meningioma or ependymoma. Reticulin staining was found to be strong in greater than 50% of the tumor.
