Background: Most common tumors in the suprasellar region are adenomas of the pituitary gland, craniopharyngiomas, cystic lesions (Rathkes cleft cysts). Supraselar meningiomas are rare and slow-growing tumors that usually arise from the tuberculum sellae or the chiasmatic sulcus. These tumors frequently invade the sella turcica because that they are mistaken for a pituitary tumor.
Methods: A case series
Results: We present a two cases of patients complaning about one side vision loss. First case is a 40 years old female, that was sent to endocrinologist because of infertility. She was diagnosed with PCOS and glucose intolernce. Due to losing eye sight and PCOS we ordered MR of pituirary gland and full hormonal blood work. Her leverls of prolactin, TSH, fT4, FSH, LH, ACTH, GH and IgF 1 were within normal range. MR of showed expansive mass in left supraselar region that compresses optical chiasma and left optic nerv. Surgical treatment was preformed and patohystological examination of tumor showed Meningeoma transitionale WHO gradus I. After surgery vision was restored with preserved pituitary function. Second case is 61 years old male, that was send to endocirnologist due to acute blury sight on right eye and headache. Full hormonal blood work up was done and was withing normal range. On the MR of pituitary gland showed meningeoma in supraselar region. Patient is scheduled for surgical treatment.
Conclusion: Supraselar meningiomas are rare and can be hard to differentiate from pituitary adenomas, and they are often sent to endocrinologist for that reason. It is really important to diferentiate appropriated surgical approach. Follow ups reqiered because of recurrence of the meningeoma.
