Pituitary (5. doi:10.1023/B:PITU..45413.62This is the first report describing magnetic resonance (MR) intensity changes of the posterior pituitary gland in the patients suffering from the classical “triphasic” diabetes insipidus (DI) after transsphenoidal surgery for pituitary adenomas. A 21-year-old female and a 54-year-old female were admitted to our hospital with the diagnosis of Cushing's disease and acromegaly due to pituitary microadenomas, respectively. No evidence of DI was found, and T1-weighted MR images exhibited “bright spot” corresponding to the posterior pituitary in both cases. Both experienced the classical “triphasic” pattern of water metabolism disturbance after successful transsphenoidal resection of pituitary adenomas, that is, polyuria-oliguria-polyuria. The MR signal hyperintensity in posterior pituitary was detected during the first polyuric phase, but the hyperintensity disappeared during the second polyuric phase. In addition, “bright spot” was restored along with the recovery from DI in the chronic phase. These findings of serial MR images supported that the first DI phase of the classical triphasic course of water metabolism disturbance was caused by secretional dysfunction of stored vasopressin from the posterior gland, whereas the second DI phase was due to impairment in the functional integrity producing vasopressin--containing granules after depletion of vasopressin in the oliguric phase.diabetes insipiduscomplicationsmagnetic resonance (MR) imagingpituitary glandpituitary adenomastranssphenoidal surgery1.Mark L, Pech P, Daniels D, Charles C, Williams A, Haughton V.
