    Pituitary Colloid Cyst
    (LIPPINCOTT WILLIAMS \& WILKINS, 2017-01-01) Guduk, Mustafa; Sun, Halil Ibrahim; Sav, Murat Aydin; Berkman, Zafer
    Colloid cysts appear most commonly in the third ventricle, their occurrence in the sellar region is uncommon. The authors report a female patient with a pituitary colloid cyst. She was diagnosed incidentally with a sellar lesion by a routine paranasal computed tomography examination performed for planning of a dental implant surgery. Radiologic examinations revealed a pituitary lesion that was removed by transnasal transsphenoidal route. Her pathologic examination revealed that the lesion was a colloid cyst. Although rare, colloid cysts should be considered in the differential diagnosis of pituitary lesions

    Intrasellar arachnoid cyst: A case report and review of the literature
    (ELSEVIER SCI LTD, 2016-01-01) Guduk, Mustafa; HamitAytar, Murat; Sav, Aydin; Berkman, Zafer
    INTRODUCTION: Arachnoid cysts (ACs) are frequently found on intracranial imaging studies but intrasellar arachnoid cysts are rarely encountered. PRESENTATION OF CASE: We present a 49-year old patient who had headaches for 6 months and cystic sellar mass was found in his cranial imaging. We operated him by transnasal transsphenoidal route. Our intraoperative diagnosis was an arachnoid cyst and pathologic studies verified our observation. He did well postoperatively and after a 1 year follow-up he was left free from future follow-ups. DISCUSSION: As common cystic lesions occupying the sellar region can simulate ACs both clinically and radiologically, neurosurgeon can fail to include ACs in making the initial diagnosis preoperatively. CONCLUSION: Although a rare entity, arachnoid cysts should be considered in the differential diagnosis of sellar region. (C) 2016 Published by Elsevier Ltd on behalf of IJS Publishing Group Ltd.
