Abstract

With improvements in diagnostic imaging techniques for the brain, pituitary tumors without neurological signs or symptoms have occasionally been found. To evaluate therapeutic strategy for incidentally found pituitary tumors ("pituitary incidentaloma"), we analyzed the result of magnetic resonance imaging findings and of ophthalmological and endocrinological studies in 3 cases with follow up. Incidentally found functioning tumors were excluded. All of 3 cases is greater than 10mm in tumor size("pituitary macroincidentaloma"). The follow-up period was 49 months, 16 months and 6 months(mean, 25.3 months) in each case. There was no evidence of tumor enlargement, endocrinological problems and visual field defect during follow-up period. Patients with pituitary incidentalomas usually follow a benign course and neurosurgical intervention is not initially required in the management even those greater than 10mm in diameter. Observation over time may be good approach to the patient with a pituitary macroincidentaloma to avoid the unnecessary risk for surgery in a patients with a stable mass.
