Abstract. Purpose:To report two cases of pituitary tumor who presented diplopia due to oculomotor nerve palsy as the chief complaint. Cases:One was a 53-year-old woman and the other was a 60-year-old man. Findings:Diplopia led to diagnosis of unilateral palsy of oculomotor nerve. Visual acuity was good in both cases. One showed blepharoptosis in the affected side. The other showed bitemporal hemianopia. Magnetic resonance imaging(MRI)led to the diagnosis of pituitary tumor that proved to be adenoma after surgery. MRI findings in the two cases were compared with that in 8 cases of pituitary tumor who showed typical bitemporal hemianopia. The 8 cases showed larger height and anteroposterior length than the present 2 cases. The 8 cases showed less width of the tumor than the 2 cases. Conclusion:The present cases illustrate that lateral extension of pituitary tumor may result in compression of oculomotor nerve in the cavernous sinus resulting in diplopia as the initial manifestation.
