INTRODUCTION Granular cell tumor （GCT） of neurohypophysis was first reported by Boyce and Beadles in 1983.Iu In 2016 WHO classification of central nervous system （CNS） tumors, GCT of neurohypophysis was defined as a distinct diagnosis.121 Here, we reported two cases of GCT of neurohypophysis misdiagnosed as pituitary adenoma and craniopharyngioma. One of the cases was a very rare fully described neurohypophysial GCT which invaded into the right cavernous sinus [Figure 1a and 1b], indicating that the benign tumor might possess aggressive features.
