Pituitary tumors are relatively common tumors accounting for almost 15% of all primary brain tumors. Pituitary macroadenomas cause mass effect on the optic apparatus causing a myriad of visual deficits. On imaging generally the anterior visual pathway is involved which may be compressed by the mass lesion. Edema in the posterior visual pathway, i.e., optic tracts on magnetic resonance imaging is a relatively common finding in craniopharyngiomas and other metastatic lesions in the pituitary region. Edema in the optic tracts in pituitary macradenomas is a very rare entity as reported by various authors in literature. We report a case of optic tract edema in a case of pituitary macroadenoma which caused rapid deterioration in the vision of the patient and improved after administration of steroids.
