Fsrt for Pituitary Macroadenomas
The use of fractionated stereotactic radiotherapy (FSRT) has evolved with technical advances in noninvasive immobilization, radiation delivery, and image guidance. The application of FSRT to pituitary tumours is aimed at reducing toxicity through improved dose conformality and reduced treatment margins. The aim of the present paper is to report our own experience and to review the published dat...
متن کاملArachnoid Cyst in Oculomotor Cistern
Oculomotor cistern is normal anatomic structure that is like an arachnoid-lined cerebrospinal fluid-filled sleeve, containing oculomotor nerve. We report a case of arachnoid cyst in oculomotor cistern, manifesting as oculomotor nerve palsy. The oblique sagittal MRI, parallel to the oculomotor nerve, showed well-defined and enlarged subarachnoid spaces along the course of oculomotor nerve. Simpl...
متن کاملThe oculomotor cistern: anatomy and high-resolution imaging.
BACKGROUND AND PURPOSE The oculomotor cistern (OMC) is a small CSF-filled dural cuff that invaginates into the cavernous sinus, surrounding the third cranial nerve (CNIII). It is used by neurosurgeons to mobilize CNIII during cavernous sinus surgery. In this article, we present the OMC imaging spectrum as delineated on 1.5T and 3T MR images and demonstrate its involvement in cavernous sinus pat...
متن کاملClinical characteristics and surgical treatment of pituitary adrenocorticotropin-secreting macroadenomas: experience from a single-centre study
Cushing’s disease due to adrenocorticotropin (ACTH)-secreting macroadenomas is rare. The aim of this study was to evaluate the clinical characteristics and biochemical assessment of patients with corticotroph macroadenomas,and the early and late outcomes of transsphenoidal surgery as the first surgical approach during a long-term follow-up. We performed a retrospective review of 20 patients wit...
متن کاملCavernous sinus invasion by pituitary macroadenomas. Neuroradiological, clinical and surgical correlation.
The classical imaging gold-standard for this diagnosis is the presence of tumor lateral to the carotid artery. Seventeen patients with pituitary macroadenomas with intraoperative confirmation of cavernous sinus invasion were studied with MRI. Only 8 patients had tumor lateral to the carotid artery; 13 had tumor within the carotid syphon and all lacked the ring enhancement of the medial wall of ...
