Abstract: Objective To summarize the experiences of diagnosis and treatment of ruptured cerebral aneurysm without subarachnoid hemorrhage(SAH). Methods The clinical manifestations, neuroradiological results, methods of treatment and outcome of 15 cases of ruptured cerebral anenrysm which presented with intracerebral hemorrhage (ICH), and/or intraventricular hemorrhage (IVH), subdural hematoma (SDH) or intramural hemorrhage(IMH) without SAH on initial CT or MRI were reviewed retrospectively. Results The initial CT or MRI in 15 cases was obtained within 2 days after onset. Of these cases, three patients presented with ICH, six with ICH and IVH, one with IVH, one with SDH, three with IMH and 1 with mixed density. There are six middle cerebral artery, four anterior communicating artery, three posterior communicating artery, one anterior cerebral artery and one posterior inferior cerebellar artery aneurysms. Thirteen patients underwent a craniotomy for clipping and two patients endovascular coiling. According Glasgow Outcome Scale (GOS),8 patients recovered well, 3 became moderately disabled, 3 were severely disabled and 1 was in vegetative state on discharge. The incidence of aneurysm rupture with ICH and/or IVH, SDH, IMH without SAH is 3.8% in this report. Conclusions Initial CT or MRI of ruptured cerebral aneurysms may presented with ICH, and/or IVH, SDH and IMH without SAH, which may have a muhifactorial cause attributable to the timing of CT or MRI, location of the aneurysm and direction of its dome, and the amount of hemorrhage. The key points to improve the outcome of such cases are to control increased intracranial pressure earlier, diagnose and manage ruptured aneurysms promptly.
