There is a 1.8cm well circumscribed calcified mass in the right middle cranial fossa. This mass lies within the temporal horn itself or in the temporal horn of the lateral ventricle. Following contrast there is no associated soft tissue component, nor enhancement. The ventricles are normal in size.
Incidental note is made of some left periorbital soft tissue swelling but no fracture is noted.
The lining cells are columnar, and appear somewhat crowded exhibiting moderate to mild variation nuclear size. Mitotic activity is not prominent. Scattered foci of xanthoma cells are present in the fibrovascular stalks. There are widely scattered stromal concretions consisting of calcified lamellar debris. In adults, they tend to occur in the fourth ventricles.
