Introduction:
The co-existence of pituitary adenoma and meningioma is extremely rare. It is even rarer in patients with no previous known risk factors for either tumour. Here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation.
Methods:
The tumours were diagnosed on MRI in the 65-year-old patient who presented with patchy visual deficits. The decision was made to undergo surgery for resection of the suprasellar meningioma and the pituitary adenoma, leaving the small olfactory groove meningioma intact. Extended endoscopic transsphenoidal surgery was performed.
Results:
Macroscopic clearance was achieved for pituitary macroadenoma and suprasellar meningioma. Postoperatively, visual field tsting and pituitary axis hormonal levels were normal. The pituitary macroadenoma was confirmed to be a non-functioning pituitary adenoma. The meningioma was diagnosed to be of WHO grade 1.
Conclusion:
The rationale for choosing such management option, including its risks and benefits in this challenging patient is discussed.
