Abstract: Objective To investigate MR findings and analyze the misdiagnosed cases of pituitary macroadenoma.Methods MR features of 1 90 patients of pituitary macroadenoma confirmed by operation and pathology were reviewed.Results 1 6 cases were mis-diagnosed as craniopharyngioma,chordoma,or meningioma.Among the sixteen cases,eight cases with cyst degeneration and hemor-rhage were misdiagnosed as craniopharyngioma;five cases with clival and sphenoid sinus destruction were misdiagnosed as chordo-mas;three cases with suprasellar and anterior cranial fossa extension were misdiagnosed as meningiomas.Conclusion Craniophar-yngioma,chordoma and meningioma should be considered in the differential diagnosis of atypical pituitary macroadenoma.The com-prehensive analysis should be based on a variety of signs.
