We are describing a case of a 14-year-old girl who developed acute cerebral infarction which was documented on diffusion-weighted magnetic resonance imaging (DWI). On detailed evaluation, diagnosis of cerebral proliferative angiopathy (CPA) was made. Incidentally, she had capillary malformation on the forehead contralateral to cerebral vascular malformation. To our knowledge, this is the first case of CPA in the literature where DWI abnormality was due to acute cerebral infarction.

ABSTRACT Cavernous hemangioma is a rare tumor of the adult larynx. These hemangiomas are confined to the larynx and generally asymptomatic. We present a rare case of a huge cavernous hemangioma in a 22-year-old patient who presented with stridor and a huge swelling in the neck, of acute onset. Detailed evaluation including 70° Hopkins laryngoscopy, contrastenhanced computed tomography (CT) scan and magnetic resonance imaging (MRI) revealed a vascular malformation with both intra- and extralaryngeal components. The typical findings of hemangioma with its management are highlighted in this article. Postoperatively, patient's voice improved and the stridor was relieved.

A newborn baby girl developed seizures right after birth. On the fourth day, the baby was examined using diffusion sequence magnetic resonance imaging (MRI) and diagnosed to have neonatal adrenoleukodystrophy. Laboratory findings confirmed the diagnosis. This is the first case of neonatal adrenoleukodystrophy (NALD) where diffusion MRI sequence helped in the diagnosis. We find association of NALD with seizures at birth is an extremely rare occurrence, and so far, only one case has been mentioned in the literature.

This paper combines optimized CSMRI algorithm (CS) and magnetic resonance imaging (MRI) to shorten the scanning time of MRI image data and improve the imaging quality. At the same time, the paper applies functional magnetic resonance imaging (BOLD-fMRI) based on the principle of blood oxygen level dependence to explore the application value of the nerve function reconstruction therapy system for the rehabilitation of active and passive motor functions in patients with acute cerebral infarction. Methods. In this paper, 20 patients with acute cerebral infarction were included. The random drawing method was used to divide them into active group and passive group, each with 10 cases. Both groups were treated with conventional medication and acupuncture. The active group used the active mode of the nerve function reconstruction treatment system to guide the patients’ limb active exercise; all training in the passive group is provided by the nerve function reconstruction treatment system to passively exercise the patients’ limbs; both groups undergo BOLD-fMRI examination before treatment and after 2 weeks of treatment and observe the activated parts of the brain functional area and corresponding parts of the two groups before and after treatment. We observe the activation volume and, at the same time, the ADL score. Results. After treatment, the activation volume and ADL scores of brain functional areas in the two groups were significantly improved compared with those before treatment, and the difference was statistically significant ( P < 0.05 ). Conclusion. The combination of optimized CSMRI algorithm (CS) and magnetic resonance imaging (MRI) can be used to evaluate the early rehabilitation efficacy of patients with acute cerebral infarction and has certain guiding value for clinical treatment.

This research was developed to investigate the effect of artificial intelligence neural network-based magnetic resonance imaging (MRI) image segmentation on the neurological function of patients with acute cerebral infarction treated with butylphthalide combined with edaravone. Eighty patients with acute cerebral infarction were selected as the research subjects, and the MRI images of patients with acute cerebral infarction were segmented by convolutional neural networks (CNN) upgraded algorithm model. MRI images of patients before and after treatment of butylphthalide combined with edaravone were compared to comprehensively evaluate the efficacy of this treatment. The results showed that compared with the traditional CNN algorithm, the running time of the CNN upgraded algorithm adopted in this study was significantly shorter, and the Loss value was lower than that of the traditional CNN model. Upgraded CNN model can realize accurate segmentation of cerebral infarction lesions in MRI images of patients. In addition, the degree of cerebral infarction and the degree of arterial stenosis were significantly improved after treatment with butylphthalide and edaravone. Compared with that before treatment, the number of patients with severe cerebral infarction or even vascular stenosis decreased significantly (P &lt; 0.05), and gradually changed to mild vascular stenosis, and the neurological dysfunction of patients was also significantly improved. In short, MRI image segmentation based on artificial intelligence neural network can well-evaluate the efficacy and neurological impairment of butylphthalide combined with edaravone in the treatment of acute cerebral infarction, and it was worthy of promotion in clinical evaluation of the treatment effect of acute cerebral infarction.

We describe a patient who presented with an acute paresis of her distal right hand suggesting a peripheral median nerve lesion. However, on clinical examination a peripheral origin could not be verified, prompting further investigation. Diffusion-weighted magnetic resonance imaging revealed an acute ischaemic lesion in the hand knob area of the motor cortex. Isolated hand palsy in association with cerebral infarction has been reported occasionally. However, previously reported cases presented predominantly as ulnar or radial palsy. In this case report, we present a rather rare finding of an acute cerebral infarction mimicking median never palsy.

Introduction: Due to improvements of catheter design and approach, catheterization-related cerebral infarctions are expected to decrease, whereas this may be counterbalanced by increased risk profile of patients who undergo catheterization. Aims: The aim of this study is to examine the prevalence and risk factors of symptomatic and asymptomatic catheterization-related cerebral infarctions in the contemporary era, using diffusion-weighted magnetic resonance imaging (MRI). Methods and Results: We retrospectively analyzed 84 patients who underwent 1237 diagnostic and interventional catheterization procedures conducted within 2010 and 2011 in our hospital and who obtained the MRI within 14 days after catheterization. Among these, 10 patients developed a neurological event underwent MRI for suspected cerebral infarction (group A), whereas 74 patients were asymptomatic and underwent MRI for various reasons (group B); 52% of patients for the assessment before coronary bypass or surgery of aortic valve, 19% for the systemic vascular assessment for atherosclerotic diseases, and 28% for other reasons. The MRI revealed a fresh cerebral infarction in 5 patients in group A and 22 patients (29.7%) in group B. In patients with infarct lesions, more number of catheters were used (p=0.01), the intravascular procedure was longer (mean ± SEM, 17.1 ± 1.7 minutes vs. 22.7 ± 2.4 minutes, p=0.06), and the mean age tended to be higher (mean ± SEM, 74.1 ± 1.67 vs. 70.4 ± 1.1, p=0.07). The features of infarction were as follows: 62.9% of patients had multiple lesions and relatively small lesions in asymptomatic patients compared to those in symptomatic patients. Conclusions: Symptomatic cerebral infarction occurred after 5 of 1237 (0.4%) procedures. However, the rate of asymptomatic catheterization-related cerebral infarctions detected using diffusion-weighted MRI remains high in high-risk patients or candidates for cardiac surgery, when the rate is compared to that reported by previous studies conducted around 10 years ago. More number of catheters used and longer procedure time were associated with cerebral infarction in present study and careful procedural planning is warranted.
