Intra-sellar schwannoma co-existing with GH-secreting pituitary adenoma.

Abstract

We present a unique example of an intra-sellar schwannoma co-existing with a growth hormone (GH)-secreting pituitary adenoma. The patient presented with acromegaly and magnetic resonance imaging (MRI) revealed an intra-sellar mass. The tumour was totally resected via a sub-labial trans-sphenoidal approach. Histopathology demonstrated the presence of a GH-secreting adenoma as well as a schwannoma at the periphery of the adenoma. After surgical excision, remission of the acromegaly occurred. Follow-up monitoring showed no evidence of recurrence of the adenoma two years after surgery. To the best of our knowledge, this is the first example of an intra-sellar schwannoma co-existing with a GH-secreting pituitary adenoma.
