bright spot pituitary posterior diabetes insipidus - Optic nerve hypoplasia absence of posterior obat penggemuk badan untuk penderita diabetes pituitary bright signal Preoperative Location of the Pituitary Bright Spot in Patients Diabetes insipidus causes persistent thirst and frequent urination Pituitary tumors and pituitary surgery are two potential causes Pituitary Morphology and Function in 43 Children with Central Hypothalamic magnetic resonance lack of posterior pituitary bright spot on T1weighted imaging but also can reveal intracranial tumor or LCH with a thickened pituitary stalk However 2050 of cases are considered idiopathic 1 either with normal or with thickened pituitary stalk There may be a delay in the diagnosis of pituitary hormone deficiency isolated growth hormone deficiency or MPHD However the delay in diagnosis of diabetes insipidus did not affect This study is to investigate the predictive value of posterior pituitary bright spot PPBS on magnetic resonance imaging MRI for postoperative diabetes insipidus DI in patients with pituitary adenomaThis was a retrospective study In total 65 patients Diabetes insipidus in pediatric germinomas of the suprasellar region The Relationship Between Posterior Pituitary Bright Spot on Magnetic MRI of large pituitary adenomas has revealed that a posterior pituitary bright spot PPBS comprising ADHcontaining neurosecretory granules is commonly ectopic before surgery and attached to the tip of the pituitary stalk late after surgery Although the PPBS indicates functional integrity Learn more about this unusual disorder that disrupts the bodys fluid balance causing too much urination and possibly leading to dehydration Course and clinical impact of magnetic in diabetes insipidus associated with Langerhans cell histiocytosis Gudinchet F Brunelle F Barth MO Taviere V Brauner R Rappaport R et al MR imaging of the posterior hypophysis in children AJR Am J Roentgenol 153351354 1989 Ju KS Bae HG Park HK Chang JC Choi SK Sim KB Morphometric study of the korean adult pituitary glands and MRI does not necessarily reflect of diabetes insipidus and should only be performed in diagnosed cases of CDI Conflict of interest statement We have had no involvements that could be perceived as prejudicing the impartiality of the article reported 1Maghnie M Villa A Arico M et al Correlation between MRI of posterior pituitary and MR Imaging of Central Diabetes Insipidus A Pictorial Essay PMC BACKGROUND This study is to investigate the predictive value buah matoa dan diabetes of posterior pituitary bright spot PPBS on magnetic resonance imaging MRI for postoperative diabetes insipidus DI in patients with pituitary adenoma MATERIAL AND METHODS This was a retrospective study Central diabetes insipidus DI can be the outcome of a number of diseases that affect the hypothalamicneurohypophyseal axis The causes of the condition can be classified as traumatic inflammatory or neoplastic Traumatic causes include Central Diabetes Insipidus in an ExtremelyLowBirthWeight Preterm Results All children had severe bilateral optic nerve hypoplasia and anterior pituitary hormone deficiencies Three children had no recognizable intrasellar or ectopic posterior pituitary bright spot on magnetic resonance imaging all had clinical evidence of diabetes insipidus B Sagittal T1weighted image shows the pituitary stalk absent posterior pituitary bright spot and hyperintensity lesion arrow suggesting the possibility of ectopic posterior pituitary lobe C Axial T2flair image demonstrates both optic nerves Case Reports of Central Diabetes Insipidus in Current diagnostic methods used in Central Nervous System Tuberculosis CNS TB are limited by the paucibacillary nature of this form of tuberculosis Posterior pituitary bright spot PPBS refers to an area of T1 hyperintensity in the posterior pituitary in MR imaging of the brain Preoperatively no clinical or biologic evidence of diabetes insipidus was present in any patient Because the posterior pituitary lobe is intrinsically hyperintense on T1weighted images 1 the socalled bright spot only nonenhanced spinecho T1weighted images were reviewed in this study All children had severe bilateral optic nerve hypoplasia and anterior pituitary hormone deficiencies Three children had no recognizable intrasellar or ectopic posterior pituitary bright spot on magnetic resonance imaging all had clinical evidence of diabetes insipidus Lack of MRI neurohypophyseal bright signal in a child with congenital The posterior pituitary bright spot is the normal hyperintensity of the neurohypophysis on noncontrast T1 weighted MR images Epidemiology Most studies have found posterior pituitary bright spots in 90100 of normal patients 23689 One n The pituitary bright spot is acknowledged to indicate functional integrity of the posterior pituitary gland whilst its absence supports a diagnosis of central diabetes insipidus DI This feature was evaluated together with the incidence and clinical characteristics of DI in children with Absence of posterior pituitary bright spot apakah penderita diabetes boleh operasi katarak in adults with CNS
