Introduction : La neurosarcoïdose hypothalamo-hypophysaire est une pathologie rare et son traitement n’est pas bien codifié ; nous rapportons à ce propos l’observation d’une patiente qui a présenté une sarcoïdose infundibulaire infiltrant le chiasma optique et qui a répondu favorablement à la corticothérapie. Observation : Mme B.F âgée de 35 ans s’était présenté en consultation pour un syndrome aménorrhée/galactorrhée, l’examen clinique ainsi que le bilan hormonal avaient mis en évidence une insuffisance antéhypophysaire, un diabète insipide et une hyperprolactinémie modérée.

Zusammenfassung. Raumforderungen in der Hypophyse haben unterschiedliche Entitäten. Am häufigsten kommen benigne Hypophysenvorderlappenadenome vor. Viele davon werden inzidentell entdeckt und sind asymptomatisch. Andere machen sich durch eine Beeinträchtigung der Hypophysenfunktion (Hypopituitarismus), eine gesteigerte Hormonsekretion (Prolaktinom, Akromegalie, Hypercortisolismus) oder durch neurologische Symptome (bitemporale Hemianopsie) bemerkbar. Die Abklärung beinhaltet eine endokrinologische Labordiagnostik sowie ein MRT der Hypophyse. Bei Nähe oder Kontakt zum Chiasma opticum ist zusätz

Zusammenfassung. Hypophysenadenome (HA) sind gutartige Tumoren aus parenchymatösen Zellen des Hypopysenvorderlappens. Es wird zwischen endokrin-inaktiven HA und hormonsezernierenden HA differenziert. Die Symptomkonstellation ist abhängig von der hormonellen Über- oder Unterfunktion und dem durch das HA erzeugten Masseneffekt. Neben Kopfschmerzen präsentieren sich HA häufig mit Visusstörungen sowie Gesichtsfeldausfällen als Folge der Kompression des Chiasma opticum. Die chirurgische Resektion über einen transsphenoidalen Zugang ist die bevorzugte Therapieoption für symptomatische oder grössenpr

Abstract:

A seven-year-old neutered male Labrador retriever was presented with behavioral changes and reduced vision. Neurological examination revealed blindness of the left eye with a positive pupillary light reflex and a decreased mental status. Blood and cerebrospinal fluid analyses showed no abnormalities. MRI revealed a deviant area located in the thalamic, hypothalamic and caudate nuclear regions. Invasion of the left optic nerve was also observed. The dog was euthanized after 38 days of palliative treatment. Necropsy showed a non-encapsulated extruding white lardaceous mass, with a diameter of 2

Abstract:

The presence of functional hypothalamo-hypophysial neurosecretory system in vertebrates has led to revise earlier views regarding the hypothalamus-pituitary relationship. The hypothalamo-neurohypophysial system which consists of hypothalamic nuclei, their axonal fibres forming tractus preoptico-hypophyses and the neurohypophysis) works as a morphological as well as a physiological connection between the hypothalamus and the pituitary gland. In fishes, fibres from the neurosecretory hypothalamic nuclei terminate in the neurohypophysis, which remains inter digitized with the adenohypophysis and

Abstract:

We experimentally study stochastic resonance (SR) in the human brain through a noise effect for entrainment dynamics of the alpha (α) wave. The measurement has been carried out under the following conditions in order to obtain clear evidence of the SR phenomenon in the central nervous system. The periodic and noisy stimuli are respectively applied to the right and the left eyes of the subject independently. When only periodic and constant (but weak enough) stimulus is applied to the right eye, it does not induce any global entrainment of α-oscillators to the stimulus frequency. In this situati

Abstract:

Single-unit recording and micropressure ejection techniques were used to test the effects of norepinephrine (NE) on the responses of neurons in the superficial layers (the stratum griseum superficiale and stratum opticum) of the hamster's superior colliculus (SC). Application of NE suppressed visually evoked responses by ≥30% in 75% of 40 neurons tested and produced ≥30% augmentation of responses in only 5%. The decrement in response strength was mimicked by application of the α2 adrenoceptor agonist, p-aminoclonidine, the nonspecific β agonist, isoproterenol, and the β1 agonist, dobutamine. T

1. Single-unit recording and iontophoretic techniques were used to test the effects of serotonin (5-HT) on the responses of neurons in the superficial layers (the stratum griseum superficiale and stratum opticum) of the hamster's superior colliculus (SC). 2. Iontophoresis of 5-HT produced a visual response suppression of 40% or greater in 78.1% (n = 50) of 64 neurons tested. 5-HT did not augment the visual responses of any of the cells tested. The average response suppression was 75.3 +/- 21.2% (mean +/- S.D.). 3. Iontophoresis of 5-HT had significantly different effects on activation of SC ce

The aim of this study was to determine the external anatomical structures of encephalon in the sparrowhawk. For this purpose, four brains of sparrowhawk were assessed for morphometric measurements and external structures. The average weight of the sparrowhawk brain was approximately 3±0,2 g., while the mean length, width and dorsoventral thickness of sparrowhawk brain were measured 24±2 mm, 19±2 mm and 4±1 mm respectively. Dorsal appearance of the sparrowhawk encephalon showed two cerebral hemispheres, cerebellum, lobus opticus, flocculus and cranial part of medulla spinalis. In lateral aspect

Introduction: The middle cerebral artery is divided into four segments: proximal M1, insular M2, opercular M3 and cortical M4. M1 extends from the bifurcation point of ACI at ACA and ACM to the insula threshold, laterally from chiasma opticum, laterally from tractus opticus and caudally from trigonum olfactorium, directed laterally, dorsally and rostrally. Early division of the M1 segment into the final trunk is possible at any of the first points of the limb insulae.

Summary We report of a male patient aged 32 years who presented with primary hyperparathyroidism. Three parathyroid glands were resected. At the age of 46 years, nervus facialis irritation was noted, and an MRI scan incidentally revealed a non-functioning pituitary adenoma with affection of the chiasma opticum. The patient underwent transsphenoidal operation resulting in pituitary insufficiency postoperatively. At the same time, primary hyperparathyroidism reoccurred and a parathyroid adenoma located at the thymus was resected. The mother of the patient died early due to multiple tumors. The p
