A rachnoid cysts account for 1% of all intracranial lesions. 4 Suprasellar arachnoid cysts are rare, comprising approximately 5%–12.5% of all intracranial arachnoid cysts. 14 , 26 , 31 Although the clinical features and radiological appearance of SACs are well described in the literature, there is still controversy concerning the best operative treatment. 10 , 29 There are several surgical procedures, including craniotomy and cyst fenestration or resection, cystoperitoneal shunt treatment, and stereotactic aspiration. Endoscopy has been recently

S uprasellar arachnoid cysts constitute 5%–12% of intracranial arachnoid cysts. 11 They are known to be associated with hydrocephalus and to cause visual and endocrine dysfunction due to their anatomical locations. 2 , 7 The most controversial topic on suprasellar cysts has been the optimal choice of surgical modality. First, operations using only fenestration precluded shunt procedures including ventriculoperitoneal shunting (VPS) and cystoperitoneal shunting (CPS) as the surgical modality of treatment. 6 Later a controversy developed between microscopic and

MRI features of the 5 cases before operation included 1) cystic masses occupying the suprasellar cistern with an MRI signal intensity similar to CSF on all sequences; 2) marked dilation of the third ventricles on axial imaging, though lateral ventricles were not dilated; and 3) sagittal T1-weighted MR images of the SSCs demonstrated the 3 diagnostic features of displacement of the pituitary stalk and optic chiasm upwards and forward, displacement of the mammillary bodies upwards and backward, and effacement of the ventral pons ( Figs. 1 – 5 ).

suprasellar region. Suprasellar extension of pituitary macroadenomas frequently occurs, and in one study it was found in nearly 80% of cases. 9 Currently, it is not known what directs extrasellar extension of pituitary tumors into the sphenoid sinus, cavernous sinuses, or suprasellar region. The sphenoid sinus is known to have a variable pneumatization pattern, with 86% well pneumatized (sellar), 11% pneumatized only to the anterior face of the sella (presellar), and 3% poorly pneumatized (conchal). 3 The right and left sphenoid sinuses are typically separated by a

D espite technological advances such as image guidance and the use of the operating microscope during the last decades, both of which have improved the surgical outcome in the management of suprasellar meningiomas, the treatment of these tumors remains challenging given the high risk of visual pathway involvement and vascular encasement of the paraclinoidal carotid artery or the anterior cerebral artery (ACA) complex. Various surgical approaches have been advocated to resect suprasellar meningiomas, with the subfrontal approach (unilateral or bilateral

Transcript 0:28 This is the case of a 25-year-old woman with a previously diagnosed dermoid cyst. She experienced one episode of seizures and aseptic meningitis 5 years ago due to rupture of the cyst. In clinic she presented with no focal neurological deficits. Recent MRI scans, however, had demonstrated enlargement of the cyst in the last 5 years. 0:52 Her most recent MRI scan demonstrated the presence of a suprasellar solid cyst lesion suggestive of a dermoid cyst. The lesion was in close contact with the pituitary gland in its posterior and lateral aspect in

brain tumors. Although this figure is lower than those of Ueki or Araki and Matsumoto, the incidence is much higher in the Japanese than in Caucasians. In this paper we present 18 cases of suprasellar germinoma. Summary of Cases Patient Population From 1941 through 1976, 2609 intracranial tumors were treated in the Department of Neurosurgery, Kyoto University Hospital. There were 132 cases of germinoma and teratoma (5% of the total series), of which 87 cases (3.3%) were histologically verified and in the remaining 45 cases the diagnosis was likely because of

, 8 , 9 , 11 , 17 , 22 , 32 , 37 In this study, we focused on the intraoperative change in the FA and the volume of the optic chiasma after its decompression in patients harboring suprasellar tumors that were treated under intraoperative MRI control. We correlated the change of the FA and the volume of the optic chiasma to the improvement of the visual status. To the best of our knowledge, this is the first study to discuss the significance of the intraoperative changes in the FA and the volume of the optic chiasma as very early predictors of the visual outcome. We

. Clinical Materials and Methods We have reviewed the records of 52 consecutive patients of all ages registered at the Princess Margaret Hospital, Toronto, during an 18-year interval, 1958 to 1976, in whom prior investigation had demonstrated a tumor in the pineal region or a tissue diagnosis of suprasellar germinoma had been made. All but one of these patients underwent radiation treatment at the Princess Margaret Hospital as part of their primary management. None had received previous radiation or specific systemic treatment other than Decadron. Initial radiological
