Abstract
OBJECTIVE The aim of this retrospective multicenter cohort study was to assess the details of the angioarchitecture of arteriovenous fistulas (AVFs) at the craniocervical junction (CCJ) and to determine the associations between the angiographic characteristics and the clinical presentations and outcomes. METHODS The authors analyzed angiographic and clinical data for patients with CCJ AVFs from 20 participating centers that are members of the Japanese Society for Neuroendovascular Therapy (JSNET). Angiographic findings (feeding artery, location of AV shunt, draining vein) and patient data (age, sex, presentation, treatment modality, outcome) were tabulated and stratified based on the angiographic types of the lesions, as diagnosed by a member of the CCJ AVF study group, which consisted of a panel of 6 neurointerventionalists and 1 spine neurosurgeon. RESULTS The study included 54 patients (median age 65 years, interquartile range 61-75 years) with a total of 59 lesions. Five angiographic types were found among the 59 lesions: Type 1, dural AVF (22 [37%] of 59); Type 2, radicular AVF (17 [29%] of 59); Type 3, epidural AVF (EDAVF) with pial feeders (8 [14%] of 59); Type 4, EDAVF (6 [10%] of 59); and Type 5, perimedullary AVF (6 [10%] of 59). In almost all lesions (98%), AV shunts were fed by radiculomeningeal arteries from the vertebral artery that drained into intradural or epidural veins through AV shunts on the dura mater, on the spinal nerves, in the epidural space, or on the spinal cord. In more than half of the lesions (63%), the AV shunts were also fed by a spinal pial artery from the anterior spinal artery (ASA) and/or the lateral spinal artery. The data also showed that the angiographic characteristics associated with hemorrhagic presentations-the most common presentation of the lesions (73%)-were the inclusion of the ASA as a feeder, the presence of aneurysmal dilatation on the feeder, and CCJ AVF Type 2 (radicular AVF). Treatment outcomes differed among the angiographic types of the lesions. CONCLUSIONS Craniocervical junction AVFs commonly present with hemorrhage and are frequently fed by both radiculomeningeal and spinal pial arteries. The AV shunt develops along the C-1 or C-2 nerve roots and can be located on the spinal cord, on the spinal nerves, and/or on the inner or outer surface of the dura mater.

Abstract
BACKGROUND Dural arteriovenous fistulas (DAVFs) of the sinus of the lesser sphenoid wing (SLSW) with leptomeningeal drainage are rare. We report a patient with a DAVF of the SLSW draining into the basal vein of Rosenthal (BVR) presenting with pontine hemorrhage. CASE DESCRIPTION A 71-year-old man presented with sudden right hemisensory disturbance of the arm and leg. Brain computed tomography scan showed left pontine hemorrhage, and cerebral angiography revealed a DAVF of the left SLSW. The fistula drained solely into the left BVR, which had an anastomosis to the left lateral mesencephalic vein, which had a varix invaginated into the left pons. The diagnosis was a DAVF of the left SLSW drained into the lateral mesencephalic vein via the bridging vein of the left SLSW, the deep middle cerebral vein, and the BVR, and a varix of the lateral mesencephalic vein caused pontine hemorrhage. The fistula was occluded by clipping through frontotemporal craniotomy. The postoperative course was uneventful, and postoperative cerebral angiography confirmed disappearance of the fistula. CONCLUSIONS A DAVF of the SLSW presenting with pontine hemorrhage is extremely rare, and DAVFs with deep leptomeningeal drainage should be included among a variety of etiologies of pontine hemorrhage.

Abstract
BACKGROUND Vein of Galen aneurysmal malformation (VGAM) is a rare pediatric vascular malformation of the brain. Genetic backgrounds are not well elucidated. We report on a monozygotic twin with VGAM and his endovascular treatment, and the genetic analyses of the twins and their parents. CASE DESCRIPTION In a monochorionic, diamniotic pregnancy of a 28-year-old healthy woman, monozygotic twins were born by emergency caesarian section because of fetal distress of the smaller twin at 25 weeks' and 4 days' gestation. Although a postnatal cranial ultrasound failed to detect VGAM in the smaller twin, mild heart failure persisted. A brain magnetic resonance (MR) examination of this twin on day 82 revealed choroidal VGAM. The twin was treated successfully by two sessions of embolization at 6 and 8 months of age. An MR examination at 1 year showed minimal residual arteriovenous shunts. He developed normally similar to the normal co-twin, with a follow-up period of 1 year and 6 months. As for the affected twin, no germline mutation or copy number variations were identified in ENG, ALK1, SMAD4, BMPR2, PTEN, RASA1, KRIT1, Marcavernin, or PDCD10 through whole-exome sequencing (WES). CONCLUSION We have reported a rare combination of a monozygotic twin and VGAM and the successful endovascular treatment. Phenotypic discordance in monozygotic twins established early in embryogenesis could be attributable to environmental or epigenetic factors.

Abstract
Basilar artery dissection (BAD) presenting with subarachnoid hemorrhage (SAH) is life-threatening, but its treatment has not been established yet. We treated two patients with ruptured BAD. They were 40-year-old and 41-year-old women. Both of them were treated conservatively during the acute stage. In one patient, radiological abnormality of BAD improved spontaneously. In another patient, reconstructive endovascular treatment (stent with coiling) was required in the chronic stage because the lesion deteriorated morphologically. Neither of them suffered from rebleeding and both had favorable outcome. We reported two patients with ruptured BAD treated conservatively during the acute stage and their outcomes were favorable. We reviewed the literature of BAD presenting with SAH and discussed the management for these lesions.

Abstract
The purpose of this study is to report the neuroradiological manifestations of hereditary hemorrhagic telangiectasia (HHT). One hundred and thirty-nine Japanese HHT patients (73 men and 66 women, aged 2–78 years) were included in this study. Diagnosis of HHT was based on genetic analysis and/or clinical diagnosis of Curaçao. They included 68 HHT1 and 37 HHT2 patients. Essentially, all patients underwent brain magnetic resonance imaging (MRI) and pulmonary computed tomography (CT). Contrast enhanced studies of brain MRI and hepatic CT were performed in a subset of patients. Catheter cerebral angiography was performed when indicated. Their neuroradiological features were reviewed retrospectively. Various imaging abnormalities were found. Brain arteriovenous malformations (AVMs) were observed in 27/136 patients (19.9%, 21 patients with HHT1 and 1 patient with HHT2). Pulmonary arteriovenous fistulas (AVFs) were found in 73/137 patients (65.2%, 45 patients with HHT1 and 6 patients with HHT2). Cerebral infarction and brain abscess were found in 17 patients and 3 patients with pulmonary AVFs, respectively. T1 high lesions in the basal ganglia suggestive of porto-venous shunts were observed in 51/136 patients (37.5%, 9 patients with HHT1 and 28 patients with HHT2). Hepatic AVMs were observed in 61/136 patients (44.9%, 15 patients in HHT1 and 29 patients in HHT2). Brain AVMs and pulmonary AVFs were more common in HHT1 than in HHT2 (both p < 0.01), but hepatic AVMs were conversely more common in HHT2 than in HHT1 (p < 0.01). In conclusion, HHT patients present with a variety of neuroradiological manifestations, which are related to substantial causes of morbid-mortality in HHT.

Abstract
Endocytoscopy (ECS) is a novel endoscopic technique that allows detailed diagnostic examination of the gastrointestinal tract at the cellular level. We previously reported that use of ECS at ×380 magnification (GIF-Y0002) allowed a pathologist to diagnose esophageal squamous cell carcinoma (ESCC) with high sensitivity (94.9%) but considerably low specificity (46.7%) because this low magnification did not reveal information about nuclear abnormality. In the present study, we used the same magnifying endoscope to observe various esophageal lesions, but employed digital 1.6-fold magnification to achieve an effective magnification of ×600, and evaluated whether this improved the diagnostic accuracy in distinguishing neoplastic from non-neoplastic lesions.We examined the morphology of surface cells using vital staining with toluidine blue and compared the histological features of 40 cases, including 19 case of ESCC and 21 non-neoplastic esophageal lesions (18 cases of esophagitis, 1 case of glycogenic acanthosis, 1 case of leiomyoma, and 1 case of normal squamous epithelium). One endoscopist classified the lesions using the type classification, and we consulted one pathologist for judgment of the ECS images as 'neoplastic', 'borderline', or 'non-neoplastic'. At ×600 magnification, the pathologist confirmed that nuclear abnormality became evident, in addition to the information about nuclear density provided by observation at ×380. The overall sensitivity and specificity with which the endoscopist was able to predict neoplastic lesions using the type classification was 100% (19/19) and 90.5% (19/21), respectively, in comparison with values of 94.7% (18/19 cases) and 76.2% (16/21), respectively, for the pathologist using a magnification of ×600. The pathologist diagnosed two non-neoplastic lesions and one case of ESCC showing an apparent increase of nuclear density with weak nuclear abnormality as 'borderline'. Among the 21 non-cancerous lesions, two cases of esophagitis that were misdiagnosed by the endoscopist were also misinterpreted as 'neoplastic' by the pathologist. We have shown, by consultation with a pathologist, that an ECS magnification of ×600 (on a 19-inch monitor) is adequate for recognition of nuclear abnormality. We consider that it is feasible to diagnose esophageal neoplasms on the basis of ECS images, and that biopsy histology can be omitted if a combination of increased nuclear density and nuclear abnormality is observed.

Abstract
The authors present a case in which transfemoral venous, transcardiac cerebral angiography was performed. In this 5-year-old girl with PHACE syndrome, both transfemoral and transbrachial arterial routes could not be used due to aortic interruption and aneurysmal dilation and small looping of the proximal portion of bilateral subclavian arteries. A 5-F balloon-tipped double-lumen catheter was advanced to the right atrium of the heart from the femoral vein. The catheter was then advanced to the left atrium through the patent foramen ovale and was further advanced to the left ventricle and then to the ascending aorta. The balloon catheter was exchanged for a 4-F catheter. Bilateral common carotid angiography was performed without difficulty. This transcardiac approach is useful in the unusual situation in which both femoral and brachial arterial routes are not available.

Abstract
OBJECTIVE Spontaneous cerebrospinal fluid rhinorrhea associated with aqueductal stenosis is rare. CSF diversion is reported to be a failure in the majority of cases. The combination of the repair of the skull base and CSF diversion is reported to be successful. We describe a case successfully treated by intradural repair with ventricular drainage followed by endoscopic third ventriculostomy. CLINICAL PRESENTATION A 28-year-old woman presented with rhinorrhea, and occasional attacks of headache, vomiting, and unconsciousness for two years. She had been diagnosed as arrested hydrocephalus for 10 years. Magnetic resonance imaging revealed triventriculomegaly with ballooning of the floor of the third ventricle, tonsilar herniation, right anterior horn herniation into the cribriform plate, and bilateral temporal lobe herniation into the temporal base. INTERVENTION A ventricular drain was inserted followed by dissection of the herniated brain and repair of the enlarged cribriform foramen with periosteal flap. Make sure that the bacterial culture negative, endoscopic third ventriculostomy has been performed. There is no recurrence of hydrocephalus and rhinorrhea for two years. CONCLUSION Direct communication between the lateral ventricle and the nasal/paranasal sinus is a rare complication of aqueductal stenosis and LOVA. Surgical repair of the skull base followed by cerebrospinal fluid diversion with endoscopic third ventriculostomy was a safe and reliable method.
