Abstract
Conventional vascular imaging methods have primarily focused on evaluating the vascular lumen. However, these techniques are not intended to evaluate vessel wall abnormalities where many cerebrovascular pathologies reside. With increased interest for the visualization and study of the vessel wall, high-resolution vessel wall imaging (VWI) has gained traction.Over the past two decades, there has been a rapid increase in number of VWI publications with improvements in imaging techniques and expansion on clinical applications. With increasing utility and interest in VWI, application of proper protocols and understanding imaging characteristics of vasculopathies are important for the interpreting radiologists to understand.

Role of Structural, Metabolic, and Functional MRI in Monitoring Visual System Impairment and Recovery. J Magn Reson Imaging 2021; 54:1706-1729. [PMID: 33009710 PMCID: PMC8099039 DOI: 10.1002/jmri.27367] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 08/24/2020] [Accepted: 08/27/2020] [Indexed: 12/13/2022] Open
Abstract
The visual system, consisting of the eyes and the visual pathways of the brain, receives and interprets light from the environment so that we can perceive the world around us. A wide variety of disorders can affect human vision, ranging from ocular to neurologic to systemic in nature. While other noninvasive imaging techniques such as optical coherence tomography and ultrasound can image particular sections of the visual system, magnetic resonance imaging (MRI) offers high resolution without depth limitations. MRI also gives superior soft-tissue contrast throughout the entire pathway compared to computed tomography. By leveraging different imaging sequences, MRI is uniquely capable of unveiling the intricate processes of ocular anatomy, tissue physiology, and neurological function in the human visual system from the microscopic to macroscopic levels. In this review we discuss how structural, metabolic, and functional MRI can be used in the clinical assessment of normal and pathologic states in the anatomic structures of the visual system, including the eyes, optic nerves, optic chiasm, optic tracts, visual brain nuclei, optic radiations, and visual cortical areas. We detail a selection of recent clinical applications of MRI at each position along the visual pathways, including the evaluation of pathology, plasticity, and the potential for restoration, as well as its limitations and key areas of ongoing exploration. Our discussion of the current and future developments in MR ocular and neuroimaging highlights its potential impact on our ability to understand visual function in new detail and to improve our protection and treatment of anatomic structures that are integral to this fundamental sensory system.

World Neurosurg 2018; 122:e561-e568. [PMID: 31108072 DOI: 10.1016/j.wneu.2018.10.100] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2018] [Revised: 10/14/2018] [Accepted: 10/16/2018] [Indexed: 12/23/2022]
Abstract
OBJECTIVE We tested the hypothesis that cerebellopontine angle (CPA) tumors are associated with a greater incidence of unruptured intracranial aneurysms (IAs). METHODS Patients with intracranial tumors (ITs) undergoing computed tomography angiography and magnetic resonance imaging were enrolled in an observational cohort study that prospectively collected age, sex, hypertension, diabetes, cerebral arteriosclerosis, tumor type, tumor location, hydrocephalus, smoking, alcohol intake, CPA tumor size, cerebral aneurysms, and cerebral arteriosclerosis. Patients with the coexistence of IA and ITwere classified as group II, whereas the others with IT as group I. RESULTS We included 1218 patients with IT for analysis. The incidence of IA was 7.1% (86/1218). A total of 31% of patients with aneurysms had CPA tumors. In a multivariate logistic regression model, a greater incidence of IA was found in female patients (odds ratio [OR] 1.726, 95% confidence interval [CI] 1.050-2.836, P=0.031) and in patients with CPA tumors (OR 3.002, 95% CI 1.822-4.947, P=0.000) after adjustment for tumor type, cerebral arteriosclerosis, and age. In female patients, CPA tumors were a unique independent risk factor of a greater incidence of IA (OR 2.270, 95% CI 1.194-4.317, P=0.012). Furthermore, cerebral arteriosclerosis was a unique independent risk factor of IA in patients with CPA tumors (OR 7.626, 95% CI 2.928-19.860, P=0.000). CONCLUSIONS These data support the hypothesis that CPA tumors are associated with a greater incidence of unruptured IAs, especially in female patients. Cerebral arteriosclerosis contributed to elevated risk of IA in patients with CPA tumors.

World Neurosurg 2017; 111:e592-e600. [PMID: 29288842 DOI: 10.1016/j.wneu.2017.12.126] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2017] [Revised: 12/18/2017] [Accepted: 12/19/2017] [Indexed: 02/05/2023]
Abstract
OBJECTIVE This study aimed to perform an integrative clinical and survival analysis for patients with coexisting glioma and intracranial aneurysm and to assess the influence of prognostic factors on overall survival (OS). METHODS A systematic literature search on PubMed and Web of Science was performed for literature in English published from 1951 to August 2017. Detailed information including clinical characteristics, treatments, critical events, and time to events for survival analysis was extracted from the included articles. Clinical characteristics of included patients were reviewed, and survival analysis was performed to identify prognostic factors of OS. RESULTS A total of 56 cases from 38 articles published in English-language journals were included in this study, and relative details were selected for integrative analysis. Univariate analysis demonstrated that age (<47/≥47 years), ruptured aneurysm (yes/no), glioma type (glioblastoma multiforme [GBM]/no GBM), World Health Organization (WHO) grade (low/high), and radiotherapy (yes/no) had a statistically significant correlation with OS (log-rank P = 0.004, P = 0.037, P = 0.004, P < 0.001, and P < 0.001, respectively). Further, multivariate analysis revealed that WHO grade (hazard ratio [HR], 22.383; 95% confidence interval [CI], 1.795-279.151; P = 0.016) and receiving radiotherapy (HR, 0.054; 95% CI, 0.009-0.333; P = 0.002) were the independent prognostic factors for OS. CONCLUSIONS This integrative survival analysis revealed that WHO grade and receiving radiotherapy were independent prognostic factors for OS, and patients with low-grade glioma and receiving radiotherapy had longer survival than counter groups. Nevertheless, similar clinical studies which should be larger samples, multicenter, and collaborative are needed further.

Abstract
RATIONALE There were a few case reports concerning epidermoid tumor coexisted with multiple cerebral aneurysms. Here, we present one case of coexistence of intracranial epidermoid tumor and multiple cerebral aneurysms and performed a literature review. PATIENT CONCERNS A 42 years old male patient was admitted to our institution with complaints of headache and dizziness. INTERVENTIONS The radiological examinations showed a hypointense lesion in the right parasellar and petrous apex region and an ipsilateral saccular aneurysm originated from the M2-M3 junction of the right middle cerebral artery (MCA) and a saccular aneurysm of the clinoid segment of right internal carotid artery (ICA). INTERVENTIONS The patients underwent a right frontotemporal approach for removal of the epidermoid tumor and clipping of the MCA aneurysm in one stage. The aneurysm located at the clinoid segment of ICA was invisible and untreated during operation. OUTCOMES No postoperative complications were found in the patient. The patient's follow up after 5 years of surgical treatment was uneventful, and the untreated aneurysm remains stable. LESSONS The coexistence of intracranial epidermoid tumor and cerebral aneurysm is a rare event. The secondly inflammation in cerebral arterial wall may be responsible for the aneurysm formation. Surgical treatment of the intracranial epidermoid tumor and cerebral aneurysm repair may be an optimal scheme in one stage.
