TL;DR: Endoscopic endonasal transposition of the pituitsary gland and its stalk can provide a valuable corridor to the retroinfundibular space and interpeduncular cistern with pituitary function preservation in the majority of patients.
Abstract: Objective The interpeduncular cistern, including the retroinfundibular area, is one of the most challenging regions to approach surgically. The pituitary gland and the infundibulum guard the region when an endonasal route is undertaken. Superior transposition of the pituitary gland and infundibulum is described as a functional means to access this complex region through a fully endoscopic, completely transnasal route. Methods Ten consecutive patients in whom a pituitary transposition was performed during an expanded endonasal approach at the University of Pittsburgh Medical Center for resection of retroinfundibular lesions were reviewed. The series consisted of seven men and three women with a mean age of 44.4 years. Pathology consisted of four craniopharyngiomas, four chordomas, and two petroclival meningiomas. Results Five patients (50%) underwent total resection of the tumor, three patients (30%) underwent near total resection ( > 95% removal), and two patients (20%) had partial resection of petroclival meningiomas with the goal of optic apparatus decompression. All four patients with visual deficits recovered their vision completely. There was no neurological deterioration. Eight patients had normal pituitary function preoperatively, seven of whom (87.5%) had confirmed function preservation postoperatively, with one of these patients experiencing transient diabetes insipidus. The remaining patient with a hypothalamic craniopharyngioma underwent complete resection with obligatory panhypopituitarism and diabetes insipidus. Conclusion Endoscopic endonasal transposition of the pituitary gland and its stalk can provide a valuable corridor to the retroinfundibular space and interpeduncular cistern with pituitary function preservation in the majority of patients. This approach should only be pursued once significant experience with endoscopic endonasal approaches has been acquired.

TL;DR: Normal high-resolution computed tomographic scans of 126 patients were reviewed to define the diameter, height of the bifurcation, and transverse position of the normal basilar artery.
Abstract: Normal high-resolution computed tomographic (CT) scans of 126 patients were reviewed to define the diameter, height of the bifurcation, and transverse position of the normal basilar artery The mean diameter of the normal basilar artery is 317 mm at the level of the pons In 92% of normal subjects, the basilar bifurcation is located in the interpeduncular cistern adjacent to the dorsum sellae or in the suprasellar cistern below the level of the floor of the third ventricle In 98% of normal individuals, the basilar artery courses in the midline or in a paramedian position, medial to the lateral margins of the clivus and dorsum sellae

TL;DR: The authors report 17 cases of large suprasellar meningiomas operated on during the 2-year period from February 1982 through March 1984, with three deaths: two from pulmonary embolism and one from gastrointestinal hemorrhage.
Abstract: The authors report 17 cases of large suprasellar meningiomas operated on during the 2-year period from February 1982 through March 1984. The tumors ranged from 4 to 9 cm in diameter. These patients presented with severe visual loss (4 were blind) and optic atrophy or papilledema. These tumors were noteworthy in their encroachment against and around the carotid arteries and optic nerves laterally, as well as against the hypothalamus with extension into the interpeduncular cistern and frontal fossa. Advanced microsurgical technique assisted in total removal of all tumor tissue with preservation of vital structures. There were three deaths: two from pulmonary embolism and one from gastrointestinal hemorrhage. The surgical technique for the total removal of these very large tumors is described.

TL;DR: Two different types of suprasellar arachnoid cysts are postulate: a noncommunicating intraarachnoids cyst of the diencephalic membrane of Liliequist and a communicating cyst that is a cystic dilation of the interpeduncular cistern.
Abstract: Object. In this study the authors identify and investigate two new classifications of suprasellar arachnoid cysts. Methods. The authors used computerized tomography cisternography, magnetic resonance (MR) imaging, and neuroendoscopy to investigate nine cases of suprasellar arachnoid cysts. A communicating cyst with early filling and early clearance of a radioopaque tracer was found in seven of nine cases; a communicating cyst with delayed filling and delayed clearance of the tracer was observed in one case; and a noncommunicating cyst was observed in the other. The MR findings indicated a variation in the position of the basilar artery (BA) bifurcation in relation to the ventral surface of the midbrain. A distance existed between the BA bifurcation and the ventral surface of the midbrain in a communicating cyst with early filling, whereas the BA bifurcation was posteriorly displaced in a communicating cyst with delayed filling and also in a noncommunicating cyst, leaving little space between the bifurcati...

TL;DR: The data suggest that patients with primary affective disorder may have a relative decrease in the size of the temporal lobe compared with normal controls.
Abstract: Magnetic resonance imaging brain scans were performed on 17 patients with primary affective disorder and 21 normal subjects. A coronal slice through the temporal lobes at the level of the pons and interpeduncular cistern was selected in each subject, and specific temporal lobe structures and the cerebral area were measured. Ratios between structures of the same hemisphere were calculated. The ratio of the temporal lobe to cerebral area was smaller in patients than controls both on the left (p less than .02) and on the right (p less than .03). The data suggest that patients with primary affective disorder may have a relative decrease in the size of the temporal lobe compared with normal controls.
