Chordoid glioma, a recently introduced clinicopathologic entity, is a rare neoplasm occurring mainly in the third ventricle and hypothalamus. The authors had experienced a case of chordoid glioma combined with Rathke's cleft cyst which occurred in the sellar and suparasellar region. Here we report clinical, radiological, and histopathological features of this neoplasm with review of literature

Diencephalic syndrome of infancy which is characterized by progressive and profound emaciation often with normal or accelerated skeletal growth, hyperkinesias, hypotension, and hypoglycemia. The profound emaciation so characteristic this syndrome has yet to be explained. The diencephalic syndrome is caused by low grade astrocytoma, ependymoma in the third ventricle including the hypothalamus. Authers report a case of diencephalic syndrome which was confirmed in this patient with ependymoma in the region of anterior hypothalamus by transcallosal approach.

Olfaction and food intake are interrelated and regulated. In the process of feeding, the metabolic signals in the body and the feeding signals produced by food stimulation are first sensed by the arcuate nucleus of hypothalamus and the nucleus tractus solitarius of brain stem, and then these neurons project to the paraventricular nucleus of hypothalamus. The paraventricular nucleus transmits the signals to other brain regions related to feeding and regulates feeding behavior. In this process, olfactory signals can be transmitted to hypothalamus through olfactory bulb and olfactory cortex to regulate feeding behavior. At the same time, gastrointestinal hormones (ghrelin, insulin, leptin, etc.) and some neurotransmitters (acetylcholine, norepinephrine, serotonin, endocannabinoid, etc.) produced in the process of feeding act on the olfactory system to regulate olfactory function, which in turn affects the feeding itself. This review summaries the research progress of the interaction between olfaction and food intake and its internal mechanism from the aspects of neuronal and hormonal regulation.

Delayed cerebral infarction after resection of craniopharyngioma is a uncommon entity, but leads to high morbidity and mortality. We present 3 such cases and discuss the etiology and pathogenesis with review of pertinent literatures. In our cases, delayed deterioration of consciousness was observed in all cases. All of them expired. The cause may be multifactorial and the surgical approach may contribute to the pathogenesis of delayed cerebral infarction. We suspect vasospasm might be the major mechanism of pathogenesis. Vessels were primed to spasm during operation due to blood in the cistern or mechanical injury. Vasoactive materials may have been liberated from the pituitary stalk or injured hypothalamus, either at the time of surgery, or later, after portions of tumor have undergone necrosis. The high degree of suspicion to detect vasospasm should be done in the case of the delayed deterioration of mental status at an early stage of craniopharyngioma surgery. Possible mechanism underlying this delayed cerebral infarction are discussed.
