[The role of susceptibility-weighted MRI in detection of ruptured aneurysm in multiple aneurysms].

Since 2008 till 2010 years 22 patients with multiple aneurysms were examined in Burdenko Neurosurgical Institute (Moscow, Russia). The series included 13 female and 9 male patients, age ranged from 28 to 62 years (mean 45 years). 68 aneurysms of different localization were discovered in these 22 patients. We also analyzed results of examination of 2 patients with solitary aneurysms in which SW-MRI was performed to confirm or exclude the fact of hemorrhage due to rupture of the aneurysm. All patients were operated microsurgically. SW-MRI is effective technique for identification of source of hemorrhage in patients with multiple aneurysms thus allowing selection of correct tactics of management. Information value of the method declines with increase of time after hemorrhage (over 2 years). SW-MRI enables verification of the fact of hemorrhage due to aneurysm in disputable cases (minimal non-specific clinical presentation, absence of hemorrhage verification).
