The 2017 World Health Organization classification described aggressive pituitary neuroendocrine tumor (PitNET) as "a with strong invasiveness and rapid growth, which is difficult to treat surgery, radiation therapy, or drug therapy," remains a challenge in the treatment of tumors. Currently, temozolomide (TMZ) first-line for PitNET. However, it not yet covered by insurance Japan. Additionally, O6-Methylguanine-DNA Methyltransferase (MGMT) expression can lead resistance, further complicating...
A recent report on computed tomography (CT) findings of contrast extravasation in subarachnoid hemorrhage (SAH) with Sylvian hematoma suggests that the occurrence is secondary to bleeding subpial space. Our patient was his sixties and admitted hospital because loss consciousness (Glasgow Coma Scale E4V1M4). SAH diagnosed plain head CT, growing hematomas were observed interhemispheric fissures following a hemorrhage. CT angiography (CTA) using dual-phase scan protocol revealed both latter...
Bilateral dissecting aneurysms presenting with subarachnoid haemorrhage are rare. The treatment strategy for bilateral vertebral artery is controversial because the contralateral already dissected and can easily undergo enlargement or bleed after non-reconstructive procedures such as trapping proximal occlusion. Here, we report a case of aneurysm that was treated stent-assisted coiling ruptured side. A 42-year-old man admitted to our hospital sudden headache (WFNS grade 1). Computed...
We describe a case of cerebral infarctions caused by transient vasoconstrictions in the posterior circulation 2 weeks after intraventricular hemorrhage without subarachnoid 35-year-old patient with Moyamoya disease. To our knowledge, this is first report where diffuse segmental basilar and arteries were recognized The complained severe acute-onset headache 14 days hemorrhage, which had different character severity from one she at onset hemorrhage. Finally, disappeared within 1 month...
Objective Postoperative nonfunctioning pituitary tumor (NFPT) regrowth is a significant concern, but its predictive factors are not well established. This study aimed to elucidate the pathological characteristics of NFPTs indicated for reoperation regrowth. Methods Pathological, radiological, and clinical data were collected from patients who underwent repeat operation NFPT at Moriyama Memorial Hospital (MMH) between April 2018 September 2023. For comparison, we also gathered initial surgery...
Surgical treatments for moyamoya disease (MMD) include direct revascularization procedures with proven efficacy, example, superficial temporal artery (STA) to middle cerebral (MCA) bypass, STA anterior occipital (OA) MCA or OA posterior bypass. In cases poor development of the parietal branch STA, auricular (PAA) is often developed and can be used as bypass donor artery. this report, authors describe double performed using only PAA in initial surgery MMD.In authors' institution, MMD...
Cerebrospinal fluid (CSF) rhinorrhea is a common complication after transsphenoidal surgery (TSS). Suturing of sellar dura effective in the prevention postoperative CSF rhinorrhea, but it may cause rare infections. Herein, we report case Aspergillus sphenoiditis with growth noted on cut ends polyvinylidene fluoride (PVDF) suture used for dural closure.A previously healthy 51-year-old woman complained abnormal odor 5 years TSS null cell adenoma. A white mass sphenoidal sinus was detected...
Implantation of left ventricular assist device (LVAD) is widely performed in patients with end-stage chronic heart failure. Infection and stroke are major complications after LVAD implantation. However, the incidence intracranial mycotic aneurysm implantation rare, no standard care. In this study, we describe a case an that was successfully treated trans-arterial embolization (TAE) N-butyl 2-cyanoacrylate (NBCA) via brachial artery. A 49-year-old man history for ischemic cardiomyopathy...
Among the psychiatric co-morbidities in epilepsy, anxiety disorders are highly frequent and have profound influence on quality of life epilepsy patients. Moringa oleifera Lam. (Moringaceae) is used traditional medicine to treat various ailments including epilepsy. However, no scientific evidence exists support its use. We studied antiepileptic anxiolytic activities aqueous extract leaves (AEMO).Antiepileptic activity was evaluated using pentylenetetrazole (PTZ) induced seizure maximum...
臨床所見・画像から何を考えるか？症例は Hunt and Kosnik grade Ⅱ，Fisher 分類 group 3 の 83 歳のくも膜下出血(SAH)患者である(Fig. 1) ． 発症前は外出や家事などもされていた元気な方であっ た．2 日前にも同様の症状があり，脳動脈瘤の再破裂を 疑う．SAH 発症以前から右眼を失明している．CT では 右後頭葉に陳旧性脳梗塞を認める．3D computed tomography angiography(CTA)では脳底動脈-左上小脳動脈 (BA-SCA)分岐部に左上方に突出して先端部分に bleb を伴う動脈瘤を認める (Fig. 2， 3) ．瘤の neck 径は 5 mm であり，dome／neck ratio＝1.27で，後床突起から までの高さは 7 である．右椎骨動脈(VA)に 70％ 程度の狭窄を認める(Fig.2A) ．胸部 X 線で大動脈弓の 石灰化を認める．
Objective: A case of metastatic bone tumor difficult to approach via the transfemoral route in which preoperative embolization through a small cervical incision was effective is presented.
The aim of this study was to determine age-related differences in outcome between clipping and coiling patients with intracranial aneurysms.We retrospectively analyzed 377 consecutive (clipping, 304 cases coiling, 73 cases) dividing them into four groups based on age as follows: <50 years, 50 59 60 69 ≥70 years.Outcomes were assessed the perioperative period 1 year later.Of symptomatic events, 7 (2.3%), including 4 (1.3%) ischemic stroke, treated none coiling.All stroke after occurred aged...
The aim of this paper was to introduce and validate our high parietal paramedian approach for tumors in the trigone lateral ventricles. This study included nine found region treated surgically institute. method is described here. First, central sulcus post-central gyrus were identified by electrodes after opening dura mater. Corticotomy performed rearward area 25mm within midline 20mm along length, avoid damage primary sensory arcuate fasciculus. A round-shaped spatula used protect...
