Unilateral exophthalmos caused by an invasive pituitary adenoma.
A case of pituitary adenoma associated with unilateral exophthalmos is reported. An intraorbital infiltrative tumor growth was verified by histopathological study. The mechanism of exophthalmos is discussed, and edema of the intraorbital tissue secondary to an inflammatory reaction or venous stasis associated with tumor cell infiltration is considered to be the cause of exophthalmos in this patient.
