Location? National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. If the pressure is of a low degree and persistent, it may be reflected only in a change in contour of a single process or of the entire sella with little evidence of decalcification, since in such cases there is a natural reparative recalcification at the site of the erosion. Erosion of the sella, or any of its related processes, is due to pressure from a contiguous mass, abnormal pulsation, or generalized pressure reflected from a more remote lesion. In the former, the decalcification results from the hyperemia of the walls of the sphenoid sinus which accompanies the infection, and in the latter both from hyperemia due to increased vascularity at the site of the tumor and from actual pressure by tumor cells which grow into the haversian canals of the adjacent bone. 28 October 2009 | Surgical and Radiologic Anatomy, Vol. These basic changes—erosion, decalcification and destruction of bone—are intimately related to one another. sella tur´cica a depression on the upper surface of the sphenoid bone, lodging the pituitary gland.

Lymphocytic hypophysitis is a rare, noninfectious inflammatory disorder of … In front of the hypophyseal fossa is the tuberculum sellae. This focal or generalized pressure produces a loss of substance of the cortex of the exposed surface of the sella or contiguous processes. On the other hand, if the pressure is acute, severe, and progressive, erosion occurs rapidly without opportunity for repair by recalcification, and the picture is soon one of complete loss of bone substance, either focal or generalized.
