A report is made here on a rare case in which occurrence of multiple cerebral aneurysm was observed after radiotherapy. The case was that of a female aged 51 who was hospitalized with the chief complaint of consciousness disorder. The patient was discharged from the hospital 1 year before, after undergoing subtotal extirpation of a tumor through the transsphenoidal sinus in a case of pituitary adenoma, and post-operative radiotherapy (topical 50 Gy). Mild hyperlipidemia associated with hypothyroidism was observed by blood biochemical test during the patient's hospitalization, and multiple cerebral infarction was also observed by CT scanning and MR imaging. Therefore, conservative treatments including intensified endocrine-supplementing treatment, centering on thyroid hormone, were attempted. The patient's thyroid gland function and hyperlipidemia improved but the consciousness disorder persisted. Exacerbation of the consciousness disorder occurred suddenly 6 weeks after the patient's hospitalization. Subarachnoid hemorrhage and hydrocephalus were observed by CT scanning. Cerebral angiography detected a saccular aneurysm in the trifurcation of the right middle cerebral artery, 3 fusiform aneurysms in the periphery of the right middle cerebral artery, 2 fusiform aneurysms in the posterior cerebral artery and irregularity of wall width in the central artery including the terminal region of the internal carotid artery. These findings were not observed at the initial hospitalization and were considered to have been formed newly afterwards. Further, these findings were observed unexceptionally in all the radiated fields. The patient died 8 weeks after hospitalization, and no autopsy finding was obtained. From the above, we presumed that radiation vasculopathy caused by the radiation therapy made one year previously, had led to the formation of multiple cerebral aneurysms.(ABSTRACT TRUNCATED AT 250 WORDS)

Subarachnoid hemorrhage (SAH) is rare in young adults and little is known about aneurysms in this subgroup. The effect of clinical and prognostic factors on the outcome based on the Glasgow Outcome Scale (GOS) scores and the predictors of unfavorable outcomes were analyzed in young adults with aneurysmal SAH. A retrospective review of the clinical parameters, including age, sex, hypertension, smoking status, hyperlipidemia, location of the cerebral aneurysm, size of the aneurysm, multiplicity, perioperative complication such as hydrocephalus, vasospasm, and hematoma, and Hunt and Hess and Fisher grading on presentation, was conducted in 108 young adults (mean age 34.8 years) managed at our institute. The outcome was classified based on GOS grading into unfavorable (GOS scores 1-3) or favorable (GOS scores 4 or 5). The overall mortality rate was 3.7% (4/108 patients). Univariate regression analysis for the outcomes at discharge found that age at the time of presentation, male sex, size of aneurysm, multiple aneurysms, hyperlipidemia, and poor Hunt and Hess and Fischer grades were associated with unfavorable outcome. Multivariate regression analysis found independent effects of sex, multiple aneurysms, size of aneurysm, and Hunt and Hess grade on the outcome at discharge. Size of aneurysm, presence of multiple aneurysms, Hunt and Hess grade, and hypertension were the predictors of outcome at mean 2-year follow up based on multivariate exact regression analysis. The multimodal approach with aggressive medical management, early intervention, and surgical treatment might contribute to favorable long-term outcomes in patients with poor expected outcomes.

Statins have been suggested in previous studies to play a protective role in experimental cerebral aneurysm (CA) models; however, no evidence supports that the application of statins can protect against aneurysm rupture in humans, and the risks of lipid levels and aneurysms remain unknown. Therefore, this meta-analysis aimed to summarize and update the epidemiological evidence to systematically assess the relationships of statin therapy and hyperlipidemia with the incidence, rupture, postrepair mortality, and all-cause mortality of abdominal aortic aneurysm (AAA) and CA. Related studies were initially retrieved from the electronic databases PubMed, Embase, and Cochrane Library from inception to August 4, 2018. Subsequently, 33 studies were enrolled into this meta-analysis, and the maximum adjusted risk ratios (RRs) as well as the corresponding 95% confidence intervals were extracted. Finally, a total of 32 observational studies involving 150,134 participants were enrolled into this meta-analysis. The RRs of statin therapy for AAA incidence, AAA rupture, CA rupture, postrepair mortality, all-cause mortality, and adverse events were 1.83 (0.56-5.98), 0.67 (0.47-0.97), 0.50 (0.18-1.36), 0.60 (0.48-0.74), 0.66 (0.58-0.75), and 0.58 (0.47-0.71), respectively. Besides, the RR of hyperlipidemia for CA rupture was 0.79 (0.67-0.93). Our findings suggested that statin therapy could reduce the risks of AAA rupture, postrepair mortality, all-cause mortality, and adverse events, without inducing the risk of AAA incidence or CA rupture, and that hyperlipidemia was associated with a lower risk of CA rupture.
