During Onyx embolization to treat brain arteriovenous malformation (AVM), carefully observing the penetration of Onyx to the nidus is important in order to avoid complications such as hemorrhage, ischemia, and difficulty with microcatheter removal. We encountered a case of Onyx extravasation during embolization of a cerebellar AVM confirmed by surgical resection and pathological analysis. The patient was a 44-year-old man with Spetzler-Martin grade I cerebellar AVM who underwent Onyx embolization prior to resection of the brain AVM...

BACKGROUND: Delayed development of intracranial aneurysms is an extremely rare complication of gamma knife surgery (GKS), and so far only 6 cases have been reported. Furthermore, there are no reported cases after GKS for trigeminal neuralgia (TN). Of the above cases, none referred to the natural history or pathophysiology of GKS-related intracranial aneurysm formation. CASE DESCRIPTION: We treated 2 patients who suffered subarachnoid hemorrhage (SAH) due to ruptures of intracranial aneurysms that developed long after GKS...

Compared to conventional therapy, several studies with prothrombin complex concentrate (PCC) have recently demonstrated its superior efficacy in rapidly replacing vitamin K-dependent factors for patients with life-threatening hemorrhage. We present a novel use of PCC in a patient with intracranial hypotension, who had received warfarin for treatment of cortical vein thrombosis. However, after anticoagulation, she proceeded to develop bilateral subdural hematomas with descent of cerebellar tonsils. Given the possibility of an occult dural puncture during labor analgesia, an epidural blood patch was performed after administration of PCC and normalization of coagulation parameters, with prompt improvement of the patient's headache...

Aneurysm of the anterior inferior cerebellar artery (AICA) is a very rare entity and the manifestation and manipulation of such aneurysms remain contentious. In this paper, we report a case where a successful surgery for an olfactory groove meningioma was performed and the patient discharged but readmitted to hospital with loss of consciousness and subsequently passed away three hours after re-admission. The patient was diagnosed with subarachnoid hemorrhage. The cause of the fatal subarachnoid hemorrhage was rupture of a new onsetting AICA dissecting aneurysm which had provided neither clinical nor radiological signs before the operation...

Here we report a case of penetrating neck injury to the posterior fossa that was shown, using high-resolution computed tomography (HRCT) and digital subtraction angiography (DSA), to involve no vascular injury. A 54-year-old man was brought to the emergency department after a penetrating injury to the left side of the posterior neck and occipital area with a knife. He was in an intoxicated state and could not communicate readily. On initial examination, his vital signs were stable and there was no active bleeding from the penetrating site...

Incidence of gliomas presenting with hemorrhage is around 3.7-7.2%. Low-grade gliomas account for <1% tumor with hemorrhage. Infants presenting with cerebellar pilocytic astrocytomas (PAs) and hemorrhage with thrombocytopenia have not been reported. We report an interesting case of a 9-month-old infant who presented to the emergency department in a drowsy state with recurrent vomiting. Laboratory investigations showed anemia, thrombocytopenia, and coagulopathy. Radiological evaluation showed a large PA with bleed...

BACKGROUND: Myoclonus is a clinical sign characterized by sudden, brief jerky, shock-like involuntary movements of a muscle or group of muscles. Dystonia is defined as a syndrome of sustained muscle contractions, frequently causing twisting and repetitive movements or abnormal postures. Cases of myoclonus or dystonia secondary to a structural lesion in the cerebellum have been reported. However, there has never been a reported case of combined myoclonus and dystonia secondary to a cerebellar lesion...

An aneurysm of the distal superior cerebellar artery (SCA) is a highly rare disease. Fusiform aneurysms of the distal SCA are particularly challenging to treat. Clipping, trapping with or without bypass using microsurgery or endovascular treatment (EVT) were used to treat this condition. We describe the case of fusiform distal SCA aneurysms treated successfully with endovascular coiling with a 3-month follow-up. A 39 year-old male was presented with subarachnoid hemorrhage (SAH) and a 15 mm fusiform aneurysm of the ambient segment of the left distal SCA...

OBJECTIVE: Cerebellar arteriovenous malformation (C-AVM) is poorly tolerated because of its aggressive natural history. The aim of this study was to delineate long-term outcomes of gamma knife stereotactic radiosurgery (GKRS) for C-AVM. METHODS: The outcomes of 45 patients who underwent GKRS for C-AVMs at our institution were retrospectively analyzed. Event free survival (EFS) was defined as free from any neurological deficits caused by AVMs or adverse phenomena from the treatment...

Occipital condyle fractures (OCFs) have been treated as rare traumatic injuries, but the number of reported OCFs has gradually increased because of the popularization of computed tomography (CT) and magnetic resonance imaging (MRI). The patient in this report presented with OCFs and C1 dislocation, along with traumatic cerebellar hemorrhage, which led to craniovertebral junction instability. This case was also an extremely rare clinical condition in which the patient presented with traumatic lower cranial nerve palsy secondary to OCFs...

OBJECTIVE: The characteristics, diagnosis, and preferred management strategies for distal posterior inferior cerebellar artery (PICA) aneurysms associated with cerebellar arteriovenous malformation (AVMs) are poorly understood. We present a case series with attention to aneurysm angioarchitecture, diagnostic imaging, treatment approaches, and a thorough review of the literature. With this information, we demonstrate a specific anatomical pattern for these aneurysms, an underreported need for conventional digital subtraction angiography (DSA) during evaluation, along with the utility of endovascular treatment with liquid embolic agents...

Cerebral air embolism is a recognized life-threatening complication, sometimes iatrogenic. Its timely diagnosis is essential because it can result in neurologic deficits or death. We report a case of a 58-year-old man who died from cerebral air embolism diagnosed by nonenhanced computed tomography scan of the head after a cardiac bypass surgery with Biventricular Assist Device and multiple vascular line placements. Autopsy revealed extensive subcutaneous emphysema, intravascular and perivascular air bubbles in the central nervous system and associated cerebral and cerebellar hemorrhagic infarction...

BACKGROUND: The dysbiosis of intestinal microbiota plays an important role in the development of gut-derived infections, making it a potential therapeutic target against multiple organ dysfunction syndrome (MODS) after sepsis. However, the effectiveness of fecal microbiota transplantation (FMT) in treating this disease has been rarely investigated. METHODS: Two male patients, a 65-year-old and an 84-year-old, were initially diagnosed with cerebellar hemorrhage and cerebral infarction, respectively, after admission...

Introduction. Terson syndrome is described as intraocular hemorrhage in association with any type of intracranial hemorrhage and is associated with higher mortality rate and vision loss. Intraocular hemorrhage in Terson syndrome may be diagnosed using computed tomography but there are false positive results. Silicone oil which is widely used for internal tamponade of complicated retinal detachments has high attenuation on computed tomography and hyperintensity on T1-weighted magnetic resonance imaging that can mimic intraocular hemorrhage...

We discuss a case with combined vestibulocochlear and facial neuropathy mimicking a less urgent peripheral vestibular pattern of acute vestibular syndrome (AVS). With initial magnetic resonance imaging read as normal, the patient was treated for vestibular neuropathy until headaches worsened and a diagnosis of subarachnoid hemorrhage was made. On conventional angiography, a ruptured distal right-sided aneurysm of the anterior inferior cerebellar artery was diagnosed and coiled. Whereas acute vestibular loss usually points to a benign peripheral cause of AVS, combined neuropathy of the vestibulocochlear and the facial nerve requires immediate neuroimaging focusing on the cerebellopontine angle...

BACKGROUND: Hypertension is a significant risk factor for intracerebral hemorrhage (ICH). Although ethnic/racial disparities related to hypertension and ICH have been reported, these previous studies were limited by a lack of Hispanics and inadequate power to analyze by ICH location. In the current study, while overcoming these prior limitations, we investigated whether there was variation by ethnicity/race of treated and untreated hypertension as risk factors for ICH. METHODS: The ERICH study (Ethnic/Racial Variations of Intracerebral Hemorrhage) is a prospective, multicenter, case-control study of ICH among whites, blacks, and Hispanics...

Although the microvascular decompression (MVD) surgery has become an effective remedy for cranial nerve rhizopathies, it is still challengeable and may result in a fatal sequel sometimes. Therefore, the operative skill needs to be further highlighted with emphasis on the safety and a preplan for management of postoperative fatal complications should be established. We retrospectively analyzed 6974 cases of MVD. Postoperatively, 46 patients (0.66 %) presented decline in consciousness with a positive finger-nose test (or failure to be tested) after wake up from the anesthesia, whom were focused on in this study...

Warfarin-induced skin necrosis (WISN) is a rare complication of anticoagulant therapy associated with a high incidence of  morbidity and mortality requiring immediate drug cessation. At particular risk are those with various thrombophilic abnormalities, especially when warfarinisation is undertaken rapidly with large loading doses of warfarin. Cutaneous findings include petechiae that progress to ecchymosis and hemorrhagic bullae. With the increasing number of patients anticoagulated as out-patients for thromboprophylaxis, we are concerned that the incidence of skin necrosis may increase...
