Abstract
OBJECTIVE Although the putamen is the most common area of spontaneous intracerebral hemorrhage, previous reports about the effects of surgery are limited. We sometimes experience a poor prognosis in patients in whom there is no damage to the internal capsule, but with injury in the long insular artery (LIA) region. The purpose of this study was to confirm the relationship between LIA damage and patient prognosis following surgery for putaminal hemorrhage. METHODS We retrospectively collected data of 287 surgical cases who presented with putaminal hemorrhage between January 2004 and March 2022. Among them, we chose patients without initial damage to the posterior limb of the internal capsule, and divided these patients into two groups, those without (Group A) and with (Group B) final damage in the LIA region. We compared positivity rates of final manual muscle test (MMT) scores≥3 and related factors. RESULTS Sixty-three of the 287 patients were included in this study. Of them, 11 cases in Group A were positive for MMT scores≥3 (68.8%) and 9 cases (19.1%) in Group B had MMT scores≥3 seven days after surgery. Group A thus had a significantly higher rate of MMT scores≥3 than group B (p=0.00). CONCLUSION In patients without initial damage to the internal capsule, LIA injury might be a key sign for predicting the functional prognosis of putaminal hemorrhage.

Abstract
We report a case of glioblastoma due to putaminal hemorrhage. Notably, the glioblastoma was located at some distance from the hematoma. A 42-year-old right-handed man presented with a sudden-onset headache, motor aphasia, and right hemiplegia. CT showed left putaminal hemorrhage and a mass lesion with a slightly high density in the midbrain away from the hematoma. Conservative treatment was initiated for the patient. Initially, we suspected a benign tumor-like cavernous malformation based on the CT findings. However, MRI showed ring enhancement of the mass lesion on contrast-enhanced MRI and hyperintensity on arterial spin labeling(ASL). A part of the wall of the putaminal hemorrhage also exhibited hyperintensity on ASL. Since we suspected a malignant brainstem tumor and a secondary intracerebral hemorrhage caused by this tumor, we performed a stereotactic brain biopsy. Histological examination revealed that the tumor was a wild-type IDH-1 glioblastoma. In the acute phase, the intracerebral hemorrhage presented as a hyperintensity on T1-weighted imaging. Therefore, it was difficult to distinguish hemorrhagic glioblastoma from an intracerebral hemorrhage. Even if an intracerebral hemorrhage is observed at common sites, it is important to consider the possibility of a malignant brain tumor and complete a prompt examination. In addition, ASL imaging may be useful in detecting hemorrhagic malignant brain tumors.

Abstract
Novel methods that stimulate neuroplasticity are increasingly being studied to treat neurological and psychiatric conditions. We sought to determine whether real-time fMRI neurofeedback training is feasible in Huntington's disease (HD), and assess any factors that contribute to its effectiveness. In this proof-of-concept study, we used this technique to train 10 patients with HD to volitionally regulate the activity of their supplementary motor area (SMA). We collected detailed behavioral and neuroimaging data before and after training to examine changes of brain function and structure, and cognitive and motor performance. We found that patients overall learned to increase activity of the target region during training with variable effects on cognitive and motor behavior. Improved cognitive and motor performance after training predicted increases in pre-SMA grey matter volume, fMRI activity in the left putamen, and increased SMA-left putamen functional connectivity. Although we did not directly target the putamen and corticostriatal connectivity during neurofeedback training, our results suggest that training the SMA can lead to regulation of associated networks with beneficial effects in behavior. We conclude that neurofeedback training can induce plasticity in patients with Huntington's disease despite the presence of neurodegeneration, and the effects of training a single region may engage other regions and circuits implicated in disease pathology.

Abstract
BACKGROUND Chronic expanding intracerebral hematoma is a well-known complication of spontaneous intracerebral hemorrhage. However, because chronic expanding intracerebral hematoma is relatively rare, it has not been studied systemically. The purpose of this study was to characterize a patient population with chronic expanding intracerebral hematoma, and to identify the predictive factors for it. METHODS We retrospectively evaluated 112 patients with spontaneous putaminal hemorrhage who were treated at our institution between January 1, 2010 and December 31, 2015. Data on age, sex, Glasgow Coma Scale score, presence of intraventricular hemorrhage, and intracerebral hemorrhage volume were collected, and their predictive values for chronic expanding intracerebral hematoma were investigated. We also evaluated the predictive value of a characteristic radiological finding at onset called the "layer sign," which was represented as a fluid level adjacent to the clot. RESULTS Chronic expanding intracerebral hematoma was observed in 4 patients (4.9%) with spontaneous intracerebral hemorrhage. Only the layer sign was significantly related to chronic expanding intracerebral hematoma (P = .003), and was found to be independently associated with chronic expanding intracerebral hematoma in a multivariate analysis (odds ratio, 18.6; 95% confidence interval, 1.19-291.0; P = .037). CONCLUSIONS The frequency of chronic expanding intracerebral hematoma in those with spontaneous intracerebral hemorrhage was estimated at 4.9%. The layer sign was a useful factor for predicting chronic expanding intracerebral hematoma.

Abstract
BACKGROUND Intracranial arterial dissection is an uncommon but well-recognized entity. Treatment remains variable, ranging from observation to intervention via the use of either surgical or endovascular techniques. Aneurysms along the lenticulostriate artery have been reported in only 41 patients. With the current case study we illustrate the effectiveness of observation in the context of a dissecting lenticulostriate aneurysm and discuss other approaches that have been used in the treatment of this particular entity. CLINICAL SUMMARY An accomplished mountain climber presented, after coitus, with acute headache, mild facial weakness, and forgetfulness. Vascular imaging studies revealed a right putaminal hemorrhage secondary to a 3-mm lenticulostriate artery dissecting aneurysm. Clinically, the patient did well, with marked improvement in presenting symptoms enabling his return to mountain climbing. Follow-up angiography showed spontaneous resolution of the arterial dissecting aneurysm. Among the 41 reported cases, 19 were idiopathic, 5 associated with hypertension, and 17 related to various conditions such as Moyamoya disease, arteriovenous malformation, systemic vasculitis, intraventricular tumor, or substance abuse. Of the 42 cases, including the present case, 28 were surgically or endovascularly managed and 12 observed. Only one of the reported cases, a 33-year-old man with Moyamoya disease, who was managed conservatively, died of rebleeding. CONCLUSION There is no common consensus in the literature on a single treatment strategy for a lenticulostriate artery aneurysm. The present case illustrates that observation and follow-up vascular imaging can be an important treatment strategy, allowing healing of the vessel wall and disappearance of the dissecting aneurysm.

Abstract
The aim of this study was to investigate where neurologists look when they view brain computed tomography (CT) images and to evaluate how they deploy their visual attention by comparing their gaze distribution with saliency maps. Brain CT images showing cerebrovascular accidents were presented to 12 neurologists and 12 control subjects. The subjects' ocular fixation positions were recorded using an eye-tracking device (Eyelink 1000). Heat maps were created based on the eye-fixation patterns of each group and compared between the two groups. The heat maps revealed that the areas on which control subjects frequently fixated often coincided with areas identified as outstanding in saliency maps, while the areas on which neurologists frequently fixated often did not. Dwell time in regions of interest (ROI) was likewise compared between the two groups, revealing that, although dwell time on large lesions was not different between the two groups, dwell time in clinically important areas with low salience was longer in neurologists than in controls. Therefore it appears that neurologists intentionally scan clinically important areas when reading brain CT images showing cerebrovascular accidents. Both neurologists and control subjects used the "bottom-up salience" form of visual attention, although the neurologists more effectively used the "top-down instruction" form.

Abstract
Ruptured aneurysms typically present as subarachnoid hemorrhage (SAH); however, they can also cause intracerebral hemorrhage (ICH) that can be mistaken for hypertensive hemorrhage. We report a rare case of a ruptured middle cerebral artery bifurcation aneurysm presenting as putaminal hemorrhage without subarachnoid hemorrhage (SAH). A 47-year-old man, with a past history of hypertension, presented with a decreased level of consciousness. Neurological examination revealed hemiparesis of the right side. A CT scan on admission demonstrated left putaminal hemorrhage without SAH. Three-dimensional CT and conventional angiograms demonstrated a superiorly directing aneurysm of the M1/M2 portion of the left middle cerebral artery (MCA). We performed aneurysmal clipping and hematoma evacuation. The postoperative course was uneventful. This case suggested that ruptured aneurysms situated on the middle cerebral artery can present as putaminal hemorrhage without SAH.

Abstract
BACKGROUND This study was carried out to examine indications for angiographic evaluation in the case of spontaneous putaminal hemorrhage. METHODS Angiographic examinations were performed on 62 consecutive adults with spontaneous putaminal hemorrhage without remarkable subarachnoid hemorrhage. Most patients were evaluated using conventional catheter angiography except for hypertensive patients over the age of 60 who underwent a magnetic resonance angiogram or a computed tomography angiogram. Computed tomography and clinical factors such as age and hypertension were correlated with the angiographic findings. RESULTS Nine of the 62 patients (15%) exhibited angiographic abnormalities, including middle cerebral artery aneurysm (n = 1), arteriovenous malformations (n = 3), moyamoya disease (n = 2), and the moyamoya phenomenon associated with a proximal middle cerebral artery occlusion (n = 3). The angiographic yield was significantly higher (1) among patients at or below the median age of 55 compared with those above (9/33, 27%, versus 0/29, 0%; p < 0.01), and (2) among patients without hypertension compared with those with hypertension (5/9, 56%, versus 4/53, 8%; p < 0.01). CONCLUSIONS Although our data could be biased due to the patient selection procedure, they suggest that angiographic evaluation is highly useful for spontaneous putaminal hemorrhage regardless of volume and shape of the hematomas, excepting hypertensive patients over 55 years of age.

Abstract
INTRODUCTION Surgical intervention in putaminal hemorrhage has been a controversial issue. The aim of this research is to evaluate the benefits of surgery for reducing the development of brain edema. MATERIALS AND METHODS Sixteen cases of putaminal hemorrhage were examined. Eight patients were treated conservatively (C group), and the other 8 patients were treated surgically (S group). Head CT scans were performed on the day of onset (day 0) in C group or performed just after surgery (day 0) in S group, and performed again once per period on days 1-7, 8-14, and 15-21. The volume of the mass including hematoma and edema (H + E) was measured using CT scans and the (H + E)/H0 ratios were calculated (H0; hematoma volume on day 0). The (H + E)/H0 ratios for each period were compared statistically between the 2 groups using a t-test. RESULTS The mean values of(H + E)/H0 ratios at each period were 2.19, 2.63, 2.53 in C group, and 1.29, 1.29, 0.66 in S group. The values in S group were significantly lower as compared with C group in every period (p < 0.01, < 0.05, < 0.01). CONCLUSIONS Hematoma volume reduction by surgery reduced the development of brain edema.

Abstract
A 32-year-old woman, gravida 0, para 0, was admitted for delivery at 40 weeks of gestation. She had no history of headache, hypertension, and toxemia. She was delivered of a healthy boy. Although she was given no medication during normal delivery, she suddenly became drowsy and developed left hemiparesis immediately after delivery. Computed tomographic (CT) scan of the brain performed on the admission day revealed a subarachnoid hemorrhage and right putaminal hemorrhage. A 4-vessel cerebral angiogram demonstrated multiple irregular narrowing of the anterior cerebral arteries, middle cerebral arteries, and posterior cerebral arteries. Her conditions seemed to improve without any medication, and the multiple stenoses were no longer observed by angiography in a follow-up examination. On the basis of these observations, she was diagnosed as having postpartum cerebral angiopathy (PCA). Pathogenesis of PCA still remaing unclear to date an ergot alkaloid derivate (ergonovine) and the hydrogenated form of the powerful vasoconstrictor ergot (bromocriptine) have been reported as cause of PCA. We will classify PCA into 3 categories: eclampsia, secondary PCA, and primary PCA. "Primary PCA" is of unknown etiology, "secondary PCA" results from a known etiology such as drugs, and "eclampsia" is a PCA with toxemia of pregnancy. We report here, that PCA may occur even in a normal pregnant woman who was given no medication, and should be considered in the diagnosis of postpartum cerebral vascular diseases in women.

Abstract
A 40-year-old man was admitted to our hospital because of consciousness disturbance, dysarthria and numbness in his right hand. Computed tomography of the head showed a cerebral hemorrhage of the left putamen. The patient was judged to have an indication of operation, and frontal craniotomy to evacuate hematoma was performed. During the operation, massive whitish pus flowed out at the time of surgery. Therefore, hemorrhage into a brain abscess was diagnosed. We reported this unique and interesting case whose brain abscess could not be differentiated from an ordinary hypertensive putaminal hemorrhage based on clinical findings and CT image. This diagnosis was not made until the patient was operated on through a craniotomy.

Abstract
OBJECTIVE Hypertensive putaminal hematoma (HPH) is a devastating type of stroke that mostly results in death or severe neurologic deficit. There seems to be no general agreement on the selection of treatment modality for individual patients. In this study a comparison has been made between conservative treatment and the results of surgical treatment through the transsylvian transinsular approach of HPH with 30 cc or more. METHODS Sixty-six patients with 30 cc volume or over of HPH, who were admitted within 36 hours after ictus, have been included in this study. Selection of the patients was made primarily according to the computerized tomography scan (CT) findings on admission. Out of the 66 patients, 47 were operated for hematoma evacuation through transsylvian transinsular approach, and the remaining 19 were accepted as a control group to be treated conservatively after their relatives declined authorization for surgery. All patients' neurologic grades and CT findings on admission were classified according to the hypertensive intracerebral hemorrhage grading system, as proposed by the cooperative study in Japan. After 6 months the outcomes of both groups were assessed according to the Glasgow outcome scale (GOS). RESULTS The statistical difference between the mortality rates was considerable (p < 0.05) with ratios of 34% and 63.1% in the surgically and conservatively treated groups, respectively. Good recovery, that is GOS score 5, was not observed in either group. In the group of surgically treated patients, 27.7% was eventually moderately disabled (GOS score 4); whereas this ratio was 5.3% among the conservatively treated group, giving a statistically significant difference (p < 0.05). Our results indicate that neurologic grades and CT findings on admission are good predictors of outcome, as the grades increase the outcome worsens. Furthermore, ventricular spread of hematoma is not a good prognostic factor. CONCLUSIONS Surgical treatment via transsylvian transinsular approach of HPH with a volume of 30 cc or more results in improved outcome as compared to conservative treatment. Operation time within the first 36 hours after ictus did not affect the outcome.

Abstract
Simultaneous occurrence of aneurysmal subarachnoid hemorrhage (SAH) and hypertensive intracerebral hemorrhage (ICH) is very rare and only two cases have been previously reported in the literatures. We present a case of 68-yr-old man with a history of untreated hypertension, who suffered from sudden onset of headache followed by right hemiparesis. Computed tomographic (CT) scan revealed SAH in the basal cistern and remote ICH at the left putamen. Cerebral angiography showed a saccular aneurysm at the anterior communicating artery. No other vascular anomaly could be found at left putaminal area. Nine days after the ictal attack of SAH, the neck of aneurysm was clipped via the left frontotemporal craniotomy. Because of the ICH at the left frontal lobe and intraventricular hematoma on postoperative CT, we performed hematoma removal and external ventricular drainage 3 hours after the first operation. Postoperative neurological status had been improved to be drowsy and he was discharged in a severely disabled state 4 weeks after surgery. We suggest that the rupture of aneurysm possibly caused a rapid increase in blood pressure and subsequently resulted in hypertensive ICH.

Abstract
This study was designed to explore the Chinese writing function of patients with subcortical stroke. Two cohorts of patient subjects with either the left or the right subcortical strokes, mainly putaminal hemorrhagic strokes, and one group of normal controls participated in the study. All participants received a writing test battery including the three aspects of writing function, that is, Spontaneous Writing, Writing to Dictation, and Writing from Copy, as well as a battery of non-writing linguistic tests. Comparing with normal controls revealed that writing function change occurred in both patient groups. The deficits in the patients with the left subcortical stroke essentially included Spontaneous Writing, and Writing to Dictation. These impairments were most likely secondary to aphasic disorders. The writing problem, mainly Writing from Copy, was noted in the patients with the right subcortical stroke. This deficit, however, was independent of the core linguistic impairment. On the basis of the results, we suggest that the lesion involving white matter in the left hemisphere probably interrupts left perisylvian cortical language organization in a manner that produces problems with spontaneous writing and writing to dictation, which are language-related, associated with lesion in the dominant hemisphere. This further suggests that left or right subcortical lesions in the putamen and surrounding white matter are associated with differential effects (language vs. non-language based effects) which are similar to such differences observed with left vs. right cortical lesions.

Abstract
BACKGROUND Spontaneous middle cerebral artery occlusion associated with moyamoya phenomenon is distinct from moyamoya disease. The hemodynamic stress on the collateral channel occasionally leads to aneurysm formation, which may manifest as hemorrhage. The etiology of this disease has not been fully understood. CASE DESCRIPTION A 63-year-old woman presented with left putaminal hemorrhage. The cerebral angiogram revealed a significant stenosis in the proximal segment of the left middle cerebral artery. Collateral arteries originating from the horizontal segment of the ipsilateral anterior cerebral artery and the ambient segment of the ipsilateral posterior cerebral artery supplied the middle cerebral artery distal to the stenosis. Both of the collateral channels had associated aneurysms that were surgically obliterated. The aneurysm on the collateral artery from the posterior cerebral artery was responsible for the putaminal hemorrhage. CONCLUSIONS Spontaneous middle cerebral artery occlusion may lead to focal moyamoya phenomenon and aneurysmal intracerebral, intraventricular, or subarachnoid hemorrhage. The presence of a co-existing anomalous collateral artery in the present case suggests a congenital etiology of the focal middle cerebral artery occlusion.

Abstract
We describe two patients (76- and 54-year-old females) with multiple hypertensive intracerebral hematomas occurring simultaneously. One patient had a right thalamic hematoma extending into the internal capsule and basal ganglia together with an other one in the left putamen. The other patient had two hematomas located ipsilaterally in the left putamen and thalamus. Their neurological examinations showed only unilateral deficits. Their magnetic resonance angiograms revealed no vascular malformations. Neuroradiological procedures are essential for the diagnosis of these multiple brain events.

Abstract
The authors present the case of a 37-year-old man with definite moyamoya disease in whom angiographic findings drastically changed. The patient presented with left hemiparesis due to lacunar infarction. Angiography initially disclosed a narrow right carotid artery (CA) siphon and severe stenosis of the horizontal segment of the left middle cerebral artery. Four years later, the patient experienced right-central facial paresis, which developed because of a small putaminal hematoma. Angiography results demonstrated occlusion of the internal CA siphons bilaterally, with moyamoya vessels. It therefore appears that in some adults, moyamoya disease is accompanied by very progressive vascular changes.

Abstract
The authors describe a case of hypertensive putaminal hemorrhage with extensive subarachnoid hemorrhage. On admission, the patient aged 71 presented right-sided motor weakness. CT scan on admission revealed left putaminal hemorrhage with extension into the ipsilateral thalamus and lateral ventricle as well as into the subarachnoid space of the suprasellar, ambient, interhemispheric and contralateral sylvian cisterns. To exclude vascular lesions, left carotid angiography was performed just after admission. The lateral view was unremarkable, but the anterior-posterior view demonstrated extravasation of contrast material from the left lateral lenticulostriate artery. The angiographic sylvian point was shifted to the lateral side. No abnormal vessels were revealed. CT scan after angiography showed exacerbation of both intracerebral and subarachnoid hemorrhages, but the consciousness level was unchanged. CT-guided stereotactic aspiration of the hematoma was performed 4 days after the onset, but failed to remove much hemtoma. The patient died of aspiration pneumonia 9 days after onset. The authors emphasize that extensive subarachnoid hemorrhage in cases with hypertensive putaminal hemorrhage may be an important finding which indicates high risk of rebleeding.
