<b><i>Introduction:</i></b> Xanthogranuloma of the sellar region is a rare benign lesion, and there are few cases reported in children. Its histogenesis is controversial, and it is difficult to strictly differentiate it from craniopharyngioma (CP), Rathke’s cleft cyst, or pituitary adenoma. <b><i>Case Presentation:</i></b> A 16-year-old boy presented with a rare xanthogranuloma of the sellar region after complaining of retardation of growth 5 years previously. The ophthalmologic evaluation revealed no visual field disturbance. Endocrinological examination revealed hypopituitarism. Magnetic resonance imaging showed an intrasellar mass extending into the suprasellar region and compressing the optic chiasma, which appeared mixed signals on T1-weighted images. Endonasal transsphenoidal resection of the tumor was performed. Histological analysis of the tumor sections demonstrated granulomatous tissue with cholesterol clefts, hemosiderin deposits, fibrous tissues, multinucleated giant cells, and lymphocyte. Thus, the tumor was pathologically diagnosed as xanthogranuloma of the sellar region, which is different from adamantinomatous CP. There was no epithelial tissue in any part of the tumor including tumor capsule but have focal necrosis and calcification. His endocrinological dysfunction did not recover, so a hormonal replacement was continuously required. <b><i>Conclusion:</i></b> Xanthogranuloma of the sellar region is a rare entity but must be considered in the differential diagnosis of lesions of the sellar region, even in pediatric population. We should think about this disease when dealing with children with stunted growth accompanied by a long medical history. Our case demonstrates the natural progression of the disease, suggesting that xanthogranuloma of the sellar region without epithelial components may be an independent disease.

✓ The authors report the uncomplicated removal of an intrasellar epidermoid cyst that on presentation mimicked a pituitary adenoma. Current controversies regarding the differentiation of this cyst from other cystic lesions of the sellar region are reviewed.

The work is devoted to assessing the results of the analysis of world literature for a period of more than 50 years: it reflects the data on the nature of the occurrence of mental disorders developing in patients with tumors of the chiasmal-sellar region against the background of water-electrolyte disorders both before and after surgery. The presented data shed light on the occurrence of the variants of mental disorders in such a specific category of neurosurgical patients, which may allow the clinician to timely determine the appropriate treatment tactics and reduce the severity of complications in the postoperative period.

Suprasellar Extension

Paragangliomas are usually benign tumors which can be found in many sites of the body, from the base of the skull down to the pelvic floor. In the central nervous system the sellar region is very rarely involved; only three well studied cases have been reported to date. We present the cytological, histological, histochemical, immunocytochemical and ultrastructural features of an intrasellar and suprasellar paraganglioma in an 84-year-old man.
