Although craniopharyngioma (CP) and pituitary adenoma (PA) are common tumors of the parasellar lesions, coexistence CP PA is very rare. A 48-year-old male visited our hospital because consciousness disturbance. The neuroimaging revealed a sellar tumor contact with massive suprasellar cyst including calcification. Preoperative diagnosis was CP, patient underwent craniotomy to resolve mass effect. histological examination disclosed adamantinomatous subsequently transsphenoidal approach chosen...
We report on a 55-year-old man who developed de novo DAVF in left ACC 5 years after curative transvenous embolization for right ACC. Angiography revealed that the lesion demonstrated more aggressive arteriovenous shunt flow than initial lesion. Successful was performed also second The authors describe possible pathophysiological mechanisms and management strategies this rare occurrence.
BACKGROUND Excess neurological stress by hemorrhagic stoke induces cardiomyopathy, namely takotsubo cardiomyopathy. Here, the authors report a case of myopathy following mechanical thrombectomy for acute large vessel occlusion. OBSERVATIONS A 73-year-old man was emergently brought to authors’ hospital because left hemiparesis and consciousness disturbance. An ischemic lesion right cerebral hemisphere internal carotid artery occlusion revealed. Emergently, endovascular treatment performed,...
In a case of 23-year-old female with Rathke's cleft cyst (RCC), unusual changes size and morphology on computed tomography (CT) magnetic resonance images (MRI) were noted in short period 3 weeks after spontaneous rupture.The CT that the intracystic isodensity was changed to hyperdensity.And MRI showed not only decrease lesion but also changing from hypo-and hyperintensity T1-and T2-weighted both images.The intraoperative findings disclosed content milky-like, hemorrhagic.We considered...
Some reports suggest that older patients with traumatic brain injury (TBI) are more likely to experience acute intracranial hemorrhage, resulting in poor outcomes. However, the association between precise chronological age and use of antithrombotic agents hemorrhage these remains unknown. The aim this study was determine factors associated outcomes TBI, including agents.
Neurofibromatosis type 1 (NF-1) is associated with vascular complications, including stenosis or the occlusion of abdominal aorta and renal arteries. However, reports on occurrence extracranial vertebral artery aneurysms are scarce. A man in his 40s had back pain was feeling unwell. Contrast-enhanced computed tomography revealed a right hemothorax involving thyrocervical trunk at arterial origin. The patient successfully treated endovascular embolization achieved full recovery. Notably, tend...
Development in mechanical thrombectomy is progressing dramatically. Tumor embolism has been rarely reported on the basis of pathological study retrieved thrombus. Herein, authors report a case cerebral tumor from advanced thyroid cancer, which was successfully treated with thrombectomy.A 57-year-old man diagnosed cancer multiple lung metastases and chemotherapy planned. He experienced left hemiparesis bought to emergency section authors' hospital. Magnetic resonance angiography revealed...
Cerebellopontine angle (CPA) tumors are a common type of benign tumors, which similar to vestibular schwannomas; however, the incidence CPA metastasis is rare. Moreover, brain from gastric rare occurrence, with an less than 1% in clinical cases. In this study, we report case 71-year-old man who was admitted our hospital symptoms nausea and gait instability for past 1 week. He had no remarkable medical history. Magnetic resonance imaging revealed tumor left CPA. Intraoperative diagnosis...
The ventricular-peritoneal shunt for hydrocephalus is a well-known and established method but sometimes complicated by malfunction due to several causes. Eosinophilic meningitis rare disease, has occasionally been reported as cause of malfunction. Here, we report the case 74-year-old woman with repeated eosinophilic silicone allergy. Originally, patient received normal pressure secondary subarachnoid hemorrhage. However, was identified 6 weeks later, first revision performed using new system...
Given the limitations of current navigation-guided brain biopsy methods, we aimed to introduce a novel method and validate its safety accuracy.This was retrospective study twenty consecutive patients who underwent at Shimane University Hospital, Japan.Clinical records 13 7 with frameless free-hand (FFNB) or framed computed tomography-guided stereotactic (CTGB) method, respectively, were retrospectively reviewed. We compared age, sex, tumor location, histological diagnosis, maximum size...
With the increasing use of carotid artery stenting (CAS), duplex ultrasound (CDU) is important for post-stented patients to check patency CAS. In our institute, stented were treated with dual antiplatelet therapy 3 months after Follow-up on 3-dimensional computed tomography (3D-CT) angiography was performed around 2 years Some also followed up annually CDU. Although major complication CAS reportedly in-stent restenosis (ISR), definitions ISR have not been standardized. From perspective...
Langerhans cell histiocytosis (LCH) is a neoplastic disease characterized by the idiopathic proliferation of cells. X-ray, computed tomography (CT), and magnetic resonance imaging (MRI) are often performed, pathology should be identified for definitive diagnosis. Single-system single-site lesions can treated surgical excision, but multi-system single-system multi-site challenging to treat excision alone; therefore, chemotherapy used after diagnosis through biopsy. We report LCH skull that...
Introduction: Proximal stenosis of the subclavian artery (SCA) shows progression to steal syndrome (SSS)/phenomenon (SSP), characterized by retrograde flow in ipsilateral vertebral (VA). Here we describe clinical manifestations and ultrasound findings VA patients with high-grade SCA, role percutaneous transluminal angioplasty (PTA) stenting SCA. Patients: Twelve (male: 10, female: 2; age: 17–86 yr) were selected from among inpatients SCA treated our department between 2009 2015. Results: The...
2015年に発表された5つのランダム化比較試験により, 機械的血栓回収療法の有効性が確立した. 本邦の適正使用指針では発症8時間以内が治療適応となるが, いわゆるwake up strokeやunknown onsetなどでは, その適応に悩む症例がある. われわれは発症から18時間経過した右内頚動脈塞栓症例において, diffusion weighted image (DWI)-fluid attenuated inversion recovery (FLAIR) mismatchの存在から機械的血栓回収療法を施行し神経症状の回復を得た症例を経験した. 本症例では右頚部内頚動脈から中大脳動脈にかけて連続する多量の血栓が存在し, 血栓の飛散が段階的に生じたことでtherapeutic time windowが延長された可能性も示唆された. 発症から時間が経過した症例においても, DWI-FLAIR mismatchが認められる症例では機械的血栓回収療法が有効となる可能性が示唆された.
Although surgery for cerebrovascular disease is an important field neurosurgeons, the number of enforcements may decrease owing to development endovascular intervention.Current neurosurgeons must acquire surgical skills with smaller cases.Here, we present our education method videos and records using information technology facilitate safe reliable neurovascular surgery.The author also disclosed results during their
脳動脈瘤の血管内治療後に，遅発性に発生する白質病変についての報告が散見される．本病態は，血管内留置デバイスから溶出するニッケルに対するアレルギー，あるいは治療中にカテーテルなどから剝離する親水コート剤に対する異物反応などが発生機序と推測されている．今回我々は，潰瘍性大腸炎を基礎疾患に有する内頚動脈瘤患者のステント併用コイル塞栓術後，遅発性に大脳白質の浮腫が発生し，病変縮退後に浮腫病変内に微小虚血巣の残存した1例を経験した．血管内治療後の遅発性白質病変とそのリスク要因について，考察を加え本症の啓発を行う．
Pseudoaneurysms typically occur iatrogenically as a result of procedures such femoral artery puncture, and are often associated with pain pulsatile mass, for which manual compression is the first treatment choice. Here we report pseudoaneurysm without mass or that was found incidentally after puncture. A 74-year-old woman left middle cerebral occlusion underwent mechanical thrombectomy using 9Fr sheath via right artery. After treatment, hemostatic device used to seal puncture site. No groin...
