The primary form is rarer. Its cause is unknown, but etiological factors have been identified. The prevalence of this condition is variable, depending on techniques of diagnosis. It may be detected fortuitously on imaging or in the presence of neurological, ocular or endocrine manifestations. <strong>Aim:</strong> We aim to report a case of empty sella turcica syndrome revealed by adrenal insufficiency in a young African black woman. <strong>Case presentation:</strong> It was an overweight young woman with signs of intracranial hypertension associated with central adrenal insufficiency. The diagnosis of empty sella was confirmed by magnetic resonance imaging. Secondarily, she developed a hypo metabolism syndrome and biology confirmed central hypothyroidism. After correction of the adrenal cortical deficit, the treatment of the thyroid deficit was administered. Evolution was favourable clinically and biologically. <strong>Conclusion:</strong> The empty sella turcica is rare and its revelation by a central adrenal insufficiency is even more. The case we report is a perfect illustration.展开更多

The sella turcica region locates in the base of skull, so the carcinoma patients in early stage often showed no intracranial hypertension and other positive signs of neural system. However, the patients presented visual field defect and hypopsia, and often went to see the doctor of ophthalmology, which resulted from that the tumor often compressed optic nerve and chiasm. We analysed the symptomatic changes of the visual organs in order to provide a diagnositic basis for sellar tumor in oph-thalmological department.Clinical materials: Of the 407 cases of sellar tumors, 296 were pituitary adenoma, 52 were craniopharyngioma, 43 were meningioma, and the rest 16 were other kinds of sellar tumors. We analysed their ocular changes of the sellar tumors and the characteristics of the tumors.Results: The sellar tumor in its early stage is mainly symptomized as visual field changes. Visual field defect was found in 92. 9% of pituitary adenoma,展开更多
