  ABSTRACT: Background: The simultaneous presence of a pituitary adenoma and a meningioma is a rare and underreported condition. The randomly encountered cases need to be reported to further allow our understanding of this collision tumors that are still not understood nor fully described. Patients and Method: We report a case of coexisting nonfunctioning pituitary adenoma and a left temporal lobe meningioma revealed by a 1-year history of progressive vision loss and occasional headaches in a 56-year-old woman. Her clinical condition worsened in the last 5 months with ptosis, cavernous sinus syndrome, and ophthalmoplegia of the right eye without papilledema. There was an improvement in the visual symptoms after subtotal resection of both lesions through a right frontotemporal craniotomy. Histology confirmed a collision tumor. The patient was referred for adjuvant treatment with gamma knife radiosurgery. He was doing well and back to his usual duties 6 months later. Conclusion: A gross total or subtotal resection with adjuvant therapy is the gold standard for the surgical management of collision tumors for a favorable patient outcome.
