Simultaneous bilateral hypertensive basal ganglia hemorrhage is a devastating cerebrovascular disease with significant high morbidity and mortality. Stereotactic aspiration and thrombolysis is a safe and effective way to clear hematomas within short time, thus reducing the neurological impairment from hematoma mass effect and secondary brain injury, improving prognosis.

Brain metastases generally present in the parenchyma of the brain. In the current report, a very rare case of brain metastasis, which simultaneously invaded the subgaleal region, the skull, and the dural and cavernous sinuses is presented. The patient, a 54-year-old female, complained of a progressive headache and exhibited the symptoms of intracranial hypertension. Coronal contrast-enhanced T1-weighted magnetic resonance imaging (MRI) showed high intensity signals in the subgaleal tissue of the left frontoparietal area, as well as in the dural and the cavernous sinuses. The patient was initially diagnosed with an intracranial infection, however, the administered treatment was ineffective. The patient subsequently underwent a biopsy and the pathological diagnosis was determined as a metastatic adenocarcinoma; a primary tumor was not identified during the examinations. Surgical removal of certain metastases and a decompressive craniectomy were performed to relieve the intracranial hypertension. However, the prognosis was unsatisfactory. The patient’s neurological condition progressively worsened and an axial computed tomography scan with a bone window demonstrated a bulging growth in the brain tissue. The patient succumbed after one month due to the widespread metastasis. Thus, this case presents the unusual clinical development of this type of metastatic adenocarcinoma. In addition, due to the intracranial hypertension, the unusual sites of the high intensity signals in the MRI and the lack of a primary tumor, the patient was misdiagnosed with an intracranial infection. Furthermore, this case highlights the necessity for conducting a biopsy as soon as possible and demonstrates the poor prognosis associated with this type of patient.

To investigate the discrepancy between 11C-methionine (MET) positron emission tomography (PET) and MRI results in primary glioblastoma multiforme (GBM) through three-dimensional (3D) volumetric analysis, we retrospectively analysed patients with primary GBM who underwent preoperative 3D MRI and MET PET and were operated between June 2016 and January 2017. Tumour delineation and volumetric analysis were conducted using MRIcron software. Tumour volumes defined by MRI (VMRI) were manually drawn slice by slice in axial and sagittal or coronal images of enhanced T1 sequence, while metabolic tumour volumes were automatically segmented in MET PET (VMET) based on three (frontal, occipital and temporal) 3D reference volumes of interest (VOI). Discrepancies were evaluated in terms of both absolute volume and percentage on the combined images. MET PET contours contained and extended beyond MRI contours in all five patients; in a subset of cases, MET PET contours extended to the contralateral hemisphere. The discrepancy between MET uptake and MRI results was 27.67 cm 3 (4.20-51.20 cm 3), i.e. approximately 39.0% (17.4-64.3%) of the metabolic tumour volume was located outside the volumes of the Gd-enhanced area. Metabolic tumour volume is substantially underestimated by Gd-enhanced area in patients with primary GBM. Quantitative volumetric information derived from MET uptake is useful in defining tumour targets and designing individualised therapy strategies in primary GBM.

Introduction Stroke survivors tend to have low motivation for rehabilitation, which prevent them from completing the rehabilitation training task effectively and participating in daily activities. Reward strategies can stimulate patients' motivation for rehabilitation, but the duration of their effect is unknown. tDCS is a technique capable of promoting plastic changes and functional reorganization of cortical functional areas.When it acts on dlPFC, it can improve the functional connectivity of brain areas associated with goal-directed behavior. Reward strategies combined with tDCS（RstDCS）have been shown to make normal individuals work harder at performing tasks. However, there are no studies on whether this combined strategy improves motivation in stroke patients and whether it has a long-lasting effect on motivation maintenance. Methods and analysis 87 stroke survivors who have low motivation and upper extremity dysfunction will be randomized to receive conventional, Rs, or RstDCS treatment. Patients in each group will undertake 15 sessions of tDCS real or sham stimulation of the left dlPFC for 3 weeks in conjunction with conventional rehabilitation or reward strategy training. Following this, the RS treatment group and RstDCS treatment group will be given a 3-week outpatient self-monitoring training program, while the conventional group will be given home rehabilitation instruction prior to discharge. Rehabilitation motivation is the primary outcome measure and will be assessed using RMS. RMS,FMA, FIM and ICF activity and social engagement scale will be compared at baseline, 3 weeks, 6 weeks, and 3 months after enrollment. Ethics and dissemination The study has been approved by the Ethics Committee of Yueyang Hospital of Integrated Chinese and Western Medicine Affiliated to SHUTCM (2021-122). All participating patients will provide written informed consent. The results will be disseminated through (open access) peer-reviewed publications, networks of scientists, professionals, and the public.

BackgroundStroke survivors often exhibit low motivation for rehabilitation, hindering their ability to effectively complete rehabilitation training task effectively and participate in daily activities actively. Reward strategies have been identified as an effective method for boosting rehabilitation motivation, but their long-term efficacy remains uncertain. Transcranial direct current stimulation (tDCS) has been recognized as a technique that facilitates plastic changes and functional reorganization of cortical areas. Particularly, tDCS can improve the functional connectivity between brain regions associated with goal-directed behavior when applied to the left dorsolateral prefrontal cortex (dlPFC). Combing reward strategies with tDCS (RStDCS) has been shown to motivate healthy individuals to exert more effort in task performance. However, research exploring the combined and sustained effects of these strategies on rehabilitation motivation in stroke survivors is lacking.Methods and designEighty-seven stroke survivors with low motivation and upper extremity dysfunction will be randomized to receive either conventional treatment, RS treatment, or RStDCS treatment. The RStDCS group will receive reward strategies combined with anodal tDCS stimulation of the left dlPFC. The RS group will receive reward strategies combined with sham stimulation. The conventional group will receive conventional treatment combined with sham stimulation. tDCS stimulation is performed over 3 weeks of hospitalization, 20 min/time, five times a week. Reward strategies refers to personalized active exercise programs for patients during hospitalization and at home. Patients can voluntarily choose tasks for active exercise and self-report to the therapist so as to punch a card for points and exchange gifts. The conventional group will receive home rehabilitation instructions prior to discharge. Rehabilitation motivation, measured using RMS. RMS, FMA, FIM, and ICF activity and social engagement scale will be compared at baseline, 3 weeks, 6 weeks, and 3 months post-enrollment to evaluate patients’ multifaceted health condition based on the ICF framework.DiscussionThis study integrates knowledge from social cognitive science, economic behavioral science, and other relevant fields. We utilize straightforward and feasible reward strategies, combined with neuromodulation technology, to jointly improve patients’ rehabilitation motivation. Behavioral observations and various assessment tools will be used to monitor patients’ rehabilitation motivation and multifaceted health condition according to the ICF framework. The aim is to provide a preliminary exploration path for professionals to develop comprehensive strategies for improving patient rehabilitation motivation and facilitating a complete “hospital—home—society” rehabilitation process.Clinical trial registrationhttps://www.chictr.org.cn/showproj.aspx?proj=182589, ChiCTR2300069068
