Mixed teratoma and meningioma in the temporoparietal region.
A case of a teratoma mixed with meningioma in the left temporoparietal region in a patient with progressive memory impairment, bradyphasia, loss of visual acuity of the left eye, and left leg weakness is presented. Histological findings showed fibroadipose tissue containing gland-like structures and lymphocytoid cells alongside a meningothelial meningioma. It is unusual for a teratoma to occur in the temporoparietal region; even more unusual is its proximity to an unrelated tumor in the same location.
