Abstract

After transsphenoidal resection of a pituitary (or other) tumor, the remaining intrasellar cavity, and sphenoid sinus are usually packed with exogenous fat or muscle to prevent cerebrospinal leak and prolapse of the optic chiasm into an empty sella. We treated two patients in whom chiasmal compression occurred postoperatively because of packing of fat. In one patient, the expected visual improvement in the postoperative period was suboptimal. The subsequent removal of fat resulted in total visual recovery. In the other patient, chiasmal compression persisted from intrasellar fat and residual tumor. Iatrogenic compression of the optic nerves or chiasm should be considered in all patients in whom visual recovery is incomplete.
