To the best of our knowledge, this case represents one of the first mycotic cerebral aneurysms from mucormycosis in a patient without an underlying skull base infection or previous intracranial surgery. Despite optimal surgical management, clinical outcomes for mycotic cerebral aneurysms are largely dependent on the success of medical therapies at controlling systemic disease.
BackgroundBoth stentriever and direct-aspiration thrombectomy effectively treat large-vessel occlusions. However, data are limited comparing clinical outcomes after aspiration-first versus stentriever-assisted aspiration for thrombectomy.MethodsA retrospective cohort study compared procedure times and radiographic outcomes after two mechanical thrombectomy techniques (aspiration first or stentriever). To minimize bias and variability inherent to multi-operator series, we assessed consecutive patients with cerebrovascular occlusions treated by a single surgeon during a 1 year period at two stroke centers. Expanded Thrombolysis in Cerebral Infarction (eTICI) grades were assessed by an investigator blinded to treatment.ResultsData from 93 patients (median age 70 years) were analyzed: 73 patients (78.5%) were treated with a strentriever-first strategy and 20 (21.5%) were treated with aspiration first, with stentriever rescue therapy required in only three of these cases following unsuccessful aspiration. There were no significant differences in patient demographics, sites of occlusion, or rates of tandem occlusions between aspiration-first and stentriever-assisted groups (p≥0.36). The rate of first-pass eTICI ≥2b was 75.0% (15/20) for aspiration-first and 52.1% (38/73) for strentriever-first groups (p=0.07), while the rate of final eTICI ≥2b was 100% (20/20) and 82.2% (60/72), respectively (p=0.04). The aspiration-first technique was associated with procedural times ≤25 min in a multivariable analysis (adjusted OR 4.77, 95% CI 1.15 to 18.39; p=0.03).ConclusionsIn this single-surgeon series, an aspiration-first technique was associated with a statistically significant improvement in eTICI outcomes and faster procedure times compared with stentriever-assisted aspiration. Further prospective studies are necessary to minimize selection bias inherent in this study design.
The anterior cingulate gyrus (ACG) is a continued focus of research as its exact role in brain function and vast connections with other anatomical locations is not fully understood. A review of the literature illustrates the role the ACG likely plays in cognitive and emotional processing, as well as a modulating role in motor function and goal-oriented behaviors. While lesions of the cingulate gyrus are rare, each new case broadens our understanding of its role in cognitive neuroscience and higher order processing. The authors present the case of an 8-year-old boy with a 1-month history of staring spells, agitated personality, and hyperphagia notable for the consumption of paper, who was found to have a 3-cm tumor in the left ACG. Following surgical resection of the tumor, his aggressive behavior and pica were ameliorated and the patient made an uneventful recovery, with no evidence of recurrence over the last 6 years since surgical resection. Here we discuss a unique behavioral presentation of pica, along with a review of the current literature, to illustrate functions of the ACG relevant to the location of the lesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
