These tumors usually appear in the sphenoid sinus, clivus, cavernous sinus, infundibulum, and suprasellar cistern. Ectopic PitNETs typically display the characteristic magnetic resonance imaging findings of pituitary adenomas. However, preoperative diagnosis of PitNETs is usually challenging because of the variety of clinical and imaging presentations, locations, and sizes. Ectopic suprasellar PitNETs resemble mass lesions in the pituitary stalk. Ectopic cavernous sinus of PitNETs are typically microadenomas in the medial wall. Ectopic sphenoclival tumors are characterized by more aggressive tumor activity than the other ectopic PitNETs. Although ectopic PitNETs are exceedingly rare, they should be considered as a differential diagnosis for masses around the sella turcica. Treatment of the disease should be individualized and may include medical care, surgical resection, gamma-knife radiosurgery, and radiotherapy. © 2024 Elsevier B.V., All rights reserved.Publication Metadata only Chronic ectopic pregnancy: magnetic resonance imaging diagnosis(MA Healthcare Ltd, 2024) Demir, Mustafa Kemal; Ecertastan, Ozge; Taşçı, Tolga; Akinci, Okan; Demir, Mustafa Kemal, Department of Radiology, Medical Park Hospital, Bursa, Turkey; Ecertastan, Ozge, Department of Radiology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Taşçı, Tolga, Department of Obstetrics and Gynecology, Bahçeşehir Üniversitesi, Istanbul, Turkey; Akinci, Okan, Department of Radiology, University of Health Sciences, Istanbul, Turkey[No abstract available]
