Abstract:
Objective To evaluate the clinical and imaging features of the sellar region lesions in children.Methods The clinical and imaging features of 112 cases with sellar region lesions were analyzed retrospectively,which were confirmed by pathology.Results 37 cases were craniopharyngiomas, which had two main symptoms of intracranial hypertension(57%)and diabetes insipidus(11%).On imaging it demonstrated as a calcified cystic tumor(81%).18 cases were gliomas, the main clinical feature of which was decreased visual acuity,13 of them were pilocytic astrocytoma, which manifested as a solid tumor with significantly enhancement(94%).16 cases were germ cell tumors,the main complaint was diabetes insipidus (75%),13 of them were germinoma, which showed iso-high density on CT and moderate enhancement after administration of contrast.And it showed high signal intensity on DWI.7 cases were hamartoma,86% patients of which showed gelasmus epilepsy,the imaging showed iso-signal masses with no enhacement in the hypothalamic papillary region.5 cases were LCH,80% of which had the complaint of diabetes insipidus,imaging findings manifested as thinkened pituitary stalk and loss of hyperintensity of posterior pituitary on T1WI.3 cases were pituitary tumors.23 cases were Rathke's cleft cysts,3 cases were arachnoid cyst.Most of the patients presented with headache.Conclusion The clinical and imaging features shows some specific features, which is helpful to improve the correct rate of diagnosis and provide the basis for further treatment.
