What are parasellar tumors?

Isaac Yang, MD
Neurosurgery
Parasellar tumors refer to brain tumors that are para- (near) and sellar, which refers to the sella turcica (a depression in the middle line of the upper surface of the sphenoid bone of the skull, in which the pituitary gland is lodged).  Therefore, parasellar tumors are tumors near the sella of the skull base and refer to skull base tumors near the pituitary gland.
Parasellar tumors are tumors that appear in the area of the brain called the sellar/parasellar region. Parasellar tumors include craniopharyngiomas, germ cell tumors, and epidermoid cysts, which are tumors that arise from developmental cells; meningiomas, tumors of the protective covering of the brain; gliomas, tumors that arise from the supporting cells in the brain; and metastatic tumors that originate in another part of the body and spread to the brain.
