1/3. Delayed rupture of traumatic intracranial pseudoaneurysm in a child following gunshot wound to the head.BACKGROUND AND OBJECTIVES: Traumatic intracranial aneurysms (TICAs) are highly unstable lesions that may rupture within minutes after formation or remain quiescent for several weeks and manifest with delayed hemorrhage and neurologic deterioration. mortality following a rupture may be 30% to 40%. Among all cerebral aneurysms, the incidence of TICAs is less than 1%; 20% to 30% of TICAs occur in children. methods AND MATERIALS: A child with a low-caliber craniocerebral gunshot wound deteriorated neurologically 12 days after the initial injury and emergency evacuation of an intracranial hematoma. A new massive left frontal hematoma was discovered, caused by the rupture of an unsuspected left pericallosal artery pseudoaneurysm. The new hematoma was evacuated, and the aneurysm was trapped using microsurgical techniques. RESULTS AND/OR CONCLUSIONS: A high index of suspicion should be maintained for delayed pseudoaneurysm genesis and rupture. A cerebral arteriogram should be obtained when significant subarachnoid hemorrhage or intraparenchymal hematomas are present, when missiles traverse major arteries, or when the pterional or cranioorbitofacial regions are violated. Treatment should be prompt.- - - - - - - - - - ranking = 1keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
2/3. Traumatic false aneurysm of the middle meningeal artery causing an intracerebral hemorrhage: case report and literature review.BACKGROUND: Traumatic false aneurysms of the meningeal arteries are rare. We report an unusual case of an intracerebral hematoma caused by the rupture of a traumatic aneurysm of the middle meningeal artery. CASE DESCRIPTION: A 64-year-old woman suffered a massive spontaneous intracerebral fronto-temporal hemorrhage. Cerebral angiogram revealed a pseudoaneurysm of the middle meningeal artery. At operation, a skull fracture was discovered in the vicinity of the aneurysm. The patient died the day after surgery. CONCLUSION: Although rare, traumatic meningeal aneurysms should be considered as a possible cause of cerebral hematoma. Because of their potential morbidity and mortality, they must be detected and treated rapidly.- - - - - - - - - - ranking = 0.22603827830363keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
3/3. Traumatic middle meningeal artery aneurysm causing intracerebral hematoma: a case report and review of literature.BACKGROUND: Traumatic aneurysms of middle meningeal artery (MMA) are rare. Traumatic MMA aneurysms usually present with extradural hematomas, whereas intradural intraparenchymal hematomas are exceedingly rare. CASE DISCUSSION: We report a 30-year-old man who presented 1 year after head injury with spontaneous right frontal intraparenchymal hematoma. Investigations revealed a MMA pseudoaneurysm, which was successfully treated surgically. CONCLUSION: Traumatic MMA pseudoaneurysm producing intracerebral hematoma (ICH) is rare and can be listed as a cause of spontaneous acute ICH.- - - - - - - - - - ranking = 0.37291440775797keywords = pseudoaneurysm, aneurysm (Clic here for more details about this article) |
