Here we report a case of ruptured dissecting aneurysm of the posterior inferior cerebellar artery[PICA] treated with proximal PICA coil occlusion using an endovascular technique. A 28-year-old man presented with acute severe headache and vomiting followed by seizure. At admission, he was drowsy, with diplopia and right ankle hypesthesia. Computed tomographic scans demonstrated a subarachnoid hemorrhage. Cerebral angiography demonstrated a dissecting aneurysm of the left proximal PICA. One day after the bleeding episode, he was undergone proximal PICA coil occlusion using an endovascular technique. The patient's postoperative course was uneventful. The decision that led to the choice of treatment is discussed.

Spinal subdural hematoma is a rarely reported disease and spontaneous spinal subdural hematomas (SSDH) without underlying pathological changes are even rarer. The patients usually show typical symtoms such as back pain, quadriplegia, paraplegia or sensory change. But rarely, patients may show atypical symptoms such as hemiparesis and misdiagnosed to cerebrovascular accident. We recently experienced a case of SSDH, where the patient initially showed vague symptoms, such as the sudden onset of headache which we initially misdiagnosed as subarachnoid hemorrhage. In this case, the headache of patient improved but the neck pain persisted until hospital day 5. Therefre, we conducted the MRI of cervical spine and finally confirmed SSDH. The patient was managed conservatively and improved without recurrence. In this case report, we discuss the clinical features of SSDH with emphasis on the importance of an early diagnosis.

In this case analysis, a patient was diagnosed with subarachnoid hemorrhage (SAH) in a 49-year-old female and showed persistent vasospasm after coil emboilzation in an aneurysm. The patient suffered from persistent vasospasm and performed angioplasty a total of 6 times. Transcranial color coded doppler (TCCD) was performed 12 times to monitor vasospasm. As a result, repetitive cerebral blood flow tests were low cost and safely performed without exposure to invasive radiation through the TCCD, and the repeatability and reproducibility of the test were confirmed with the capabilities of a trained professional radiological technologist.

In cases of hyponatremia induced by brain damage, it is important to distinguish between the syndrome of inappropriate anti-diuretic hormone secretion (SIADH) and cerebral salt wasting syndrome. A ventriculoperitoneal (VP) shunt is the standard treatment for hydrocephalus, and external lumbar drainage (ELD) is an option to evaluate the effect of a VP shunt. However, ELD has potential complications, such as subarachnoid hemorrhage, meningitis, and rarely hyponatremia. Therefore, we report a case of a patient with cerebral salt-wasting syndrome resulting from ELD to treat normal-pressure hydrocephalus during the rehabilitation of acute ischemic stroke.

Ruptured intracranial aneurysms in infants are rare and infantile fusiform anterior cerebral artery (ACA) aneurysms are much rarer. In this report, we described the case of a 7-month-old infant with a ruptured fusiform ACA aneurysm who presented with seizure and underwent endovascular treatment. The patient was initially in a coma and the neurologic condition did not improve after treatment. The clinical characteristics of the case and literature review were discussed.

Orbital floor fractures are commonly encountered, but the dislocation of the eyeball into the maxillary sinus is relatively rare. When it does occur, globe dislocation can have serious consequences, including vision loss, enucleation, and orbito-ocular deformity. Immediate surgical intervention is typically attempted when possible. However, severe comorbidities and poor general health can delay necessary surgery. In this report, we present the surgical outcomes of a 70-year-old woman who received delayed treatment for traumatic eyeball dislocation into the maxillary sinus due to a subarachnoid hemorrhage and hemopneumothorax. Additionally, we propose a treatment algorithm based on our clinical experience and a review of the literature.

Intracranial aneurysms arise in 1-2% of the population and usually present as hemorrhagic strokes. Spontaneous thrombosis of a ruptured intracranial aneurysm occurs in 1-3% and most commonly in giant aneurysms, with complete thrombosis in just 13-20% of the cases. Thrombosis of smaller aneurysms is rare. Here we present a case of a patient who presented with a ruptured intracranial aneurysm that subsequently thrombosed, discovering a neighboring de-novo aneurysm during follow-up. We hypothesized that after thrombosis, the hemodynamic characteristics that contributed to the formation of the first aneurysm were replicated.

Subarachnoid hemorrhage secondary to rupture of an aneurysm is a severe condition, associated with a high rate of morbidity and mortality. There are few cases in the literature of rupture of an aneurysm of the persistent trigeminal artery. This is the case of a 62-year-old female who has suffered multiple ruptures of aneurysms, in different decades of her life, with the development of de novo aneurysm, been this the presented case, a rupture of aneurysm of the persistent trigeminal artery. This patient has survival to these conditions and remain without important morbidity. The case manifested with a clinical picture of third and seventh cranial nerve deficit, which this last one, there are not previous publications of cases with this deficit. This aneurysm was embolized with coils, and the postoperative condition was satisfactory, been discharged at 4 postoperative days.

When aneurysmal subarachnoid hemorrhage due to multiple aneurysms is suspected, identifying the rupture site is essential to determine the exact surgical site, but it may not be easy. Even if embolization is adequately performed, complications may remain. Typical complications include rebleeding and hydrocephalus in the early phase and delayed cerebral ischemia in the delayed phase. Herein, we describe a case of rupture of an intracranial aneurysm after performing embolization for a different ruptured intracranial aneurysm in a patient with multiple intracranial aneurysms. Patients with multiple intracranial aneurysms need to be considered for closer observation than those with a single ruptured intracranial aneurysm, even if the patient's prognosis is good.

Objective : Acute hydrocephalus can be caused by many pathologic conditions such as sub- arachnoid hemorrhage, intraventricular hemorrhage, inflammatory diseases. External ventricular drainage(EVD) through trephination of the skull is essential procedure for progressing or persistent symptomatic acute hydrocephalus. If the EVD can not be removed in short period, the chance of ventriculitis increases and periodic transposition of the draining catheter should be considered. Shunt procedure can not be performed in acute hemorrhage or infectious condition because of the risk of shunt malfunction or intra-abdominal spreading of the infection, respectively. The authors replaced EVD with continuous lumbar drainage(CLD) for the purpose of controlling acute hydrocephalus and preventing ventriculitis simultaneously, or treating ventriculitis more effectively in case of infection which had already broken out. CLD has many advantages over EVD, although, it can complicate disastrous downward brain herniation in patients with elevated intracranial pressure. The authors performed CLD with EVD maintained and then tested the possibility of the brain herniation with quite simple method. If the CLD was proven as safe through the test, EVD could be replaced with it without terrible herniation. Material and Method : Between September 1998 and April 1999, 10 patients underwent CLD in replacement of EVD. Among them, 5 were patients with aneurysmal subarachnoid hemorrhage, 2 were patients with thalamic hematoma and intraventricular hemorhage and 3 were patients with traumatic intracranial hemorrhage. Results : In eight of them the replacements were successfully done and one of them died on account of medical illness. In two of them the replacement could not be performed because of the risk of herniation and all expired owing to ventriculitis. Two patients required permanent shunt operation. Conclusion : This article provides a valuable alternative method of treatment for persistent symptomatic hydrocephalus which can not be managed with shunt operation immediately.
