Epidermoid cyst of the sphenoid sinus with extension into the sella turcica presenting as pituitary apoplexy: case report.

Background: Epidermoids of the central nervous system are rare tumors. They are usually found in the fourth decade of life and most commonly off midline in the cerebellopontine angle. We report here a rare case of an epidermoid arising from the sphenoid sinus with extension into the sella and adjacent structures with acute onset of neurological deficit.

Does antegrade cerebral perfusion protect the brain during deep hypothermic circulatory arrest?

Purpose: This study compares cerebral protection using no cerebroplegia and using antegrade cerebroplegia with variable flow rates during deep hypothermic circulatory arrest (DHCA).

Methods: Twenty healthy neonatal piglets (2.5-3.
