Cerebral venous thrombosis presenting with subarachnoid hemorrhage (SAH) is very rare. We report a case of cerebral venous sinus thrombosis as an initial manifestation of SAH. A 14-year-old boy was admitted with progressive headache, nausea, vomiting, diplopia, and gait disturbance. Cerebral computed tomography scan showed a widely SAH in the basal cisterns, bilateral sylvian fissures, and anterior interhemispheric fissure. Cerebral angiography was performed to detect any aneurysm in intracranial vasculature as a cause of SAH; however, the totally thrombosed superior sagittal sinus, galenic vein, and straight sinus were the sole abnormal findings.

A patient with moyamoya disease presenting with subarachnoid hemorrhage (SAH) is reported. A 38-year-old Japanese woman developed a sudden onset headache and nausea during hospitalization for a cerebral infarct in the right frontal lobe. CT scan showed SAH in the left frontal sulci. Cerebral angiogram showed stenosis of the distal bilateral internal carotid arteries with moyamoya vessels, and significant transdural anastamoses from the left external carotid artery to cortical arteries on the left frontal cortex. The patient was kept normotensive and underwent a right-sided surgical revascularization procedure, remaining well for three years. SAH not due to ruptured aneurysm in moyamoya disease is rare. The cause of the SAH was thought to be disruption of the transdural anastomotic vessels. Recognition of these fragile vessels in moyamoya disease is essential.

The authors herein report a case of a ruptured dissection of the superior cerebellar artery (SCA). A 68-year-old man presented with symptons of sudden headache and nausea. The CT scan revealed the presence of both a subarachnoid hemorrhage (SAH) and acute hydrocephalus. The left vertebral angiogram showed an fusiform dilatation in the cerebellomesencephalic segment of the left SCA. Endovascular embolization of the aneurysm and SCA was successfully performed using Guglielmi detachable coils (GDCs). No delayed ischemic deficits were observed after the treatment. A dissection of the distal segment of the SCA is a very rare occurrence. We believe endovascular embolization using GDCs to be an effective and less invasive therapy for the treatment of an SCA dissection with SAH.

This 34-year-old man with a 10-year history of HIV infection presented with an acute onset of severe headache, fever, nausea, vomiting, and left-sided weakness. Computed tomography (CT) scanning demonstrated diffuse subarachnoid hemorrhage (SAH), and subsequent CT angiography revealed multiple large and giant intracranial aneurysms with diffuse vasculopathy. The patient's CD4-positive cell count was low, although he had been receiving combination antiretroviral therapy and his viral load was undetectable. The preponderance of the literature on HIV-infected patients with intracranial vascular involvement has concerned children in whom there is a high viral load. In such children, appropriate antiretroviral therapy may result in the complete resolution of these vascular abnormalities. In the present study, the authors report on the unique case of an HIV-infected adult patient who presented with SAH, diffuse intracranial vasculopathy, and multiple giant and fusiform aneurysms, despite having received adequate antiretroviral treatment and demonstrating an undetectable viral load. Intracranial vascular involvement in these patients may become increasingly common as the management of HIV infection continues to improve and afflicted patients survive for longer periods.

A normal component of the flora of the oropharynx, Neisseria sicca was first isolated in 1906 and has since been reported as a rare cause of various human infections including endocarditis, pneumonia, sinusitis, sepsis, and urethritis. We report the case of a 44-year-old African-American female with a history of hypertension who presented with complaints of right frontal headache, nausea, photophobia, and vomiting. A computed tomography scan of the patient's brain showed a large subarachnoid hemorrhage, and an arteriogram confirmed a large posterior communicating artery aneurysm. A ventriculostomy tube was placed, and the patient subsequently developed an elevated temperature and elevated white blood cell count. Cerebrospinal fluid studies showed elevated protein and glucose levels and cultures positive for N. sicca. This is only the seventh reported case of culture-proven meningitis related to N. sicca, and the first reported case associated with intracranial hemorrhage and ventriculostomy tube placement.

Spontaneous intracranial hypotension (SIH) is a syndrome that was largely unknown until the advent of MRI. The incidence of SIH is estimated at 5 per 100,000, which is half the incidence of subarachnoid hemorrhage. The major feature is a postural headache of acute or subacute onset. This headache is absent or minimal when the patient is lying down and rapidly worsens to great intensity when the patient sits or stands. Other features may include nausea, vomiting, vertigo, tinnitus, and marked exacerbation by Valsalva maneuver. SIH is due to a leak of cerebrospinal fluid from a tear in the dural membrane, which occurs most often at the exit zones where the cervical spinal roots leave the subarachnoid space. Other leak sites may be the vestibular system, the cribriform plate, or the pituitary fossa. If the leak continues, the brain loses buoyancy within the cranial space and sags toward the foramen magnum. This, in turn, may produce subdural hygroma or hematoma, brainstem compression, focal cranial nerve palsies, or cerebellar tonsillar herniation. The initial therapy is generally strict bed rest. If this fails, an epidural blood patch is usually successful in sealing the leak and restoring brain buoyancy. A significant minority of patients require a repeat epidural blood patch. If the blood patch fails, a surgical approach may be needed. Repair of the leak and restoration of brain buoyancy will stop the postural headache and, in most cases, will reverse the complications.

A 61-year-old woman had suffered from severe headache and nausea over 20 times during the last 43 years. An subarachnoid hemorrhage (SAH) was detected by spinal puncture in some other hospitals, but the source of hemorrhage remained unknown in spite of repeated angiography. At the age of 61, she was diagnosed as having normal pressure hydrocephalus, and received a ventriculo-peritoneal shunt. She suffered from sudden headache 12 days after surgery. A CT scan showed a SAH and enlargement of the pineal mass. The tumor was totally removed via the occipital interhemispheric transtentorial approach and was diagnosed histologically as a pineocytoma. She has been free from SAH for three years since removal of the tumor. Pineal apoplexy should be considered as a cause of SAH.

Cervical dural arteriovenous fistulas (dAVFs) are a rare cause of intracranial subarachnoid hemorrhage (SAH) but should be considered when other sources are not found. Subarachnoid hemorrhage caused by dAVF is thought to occur as a result of venous hypertension in most cases. The clinical presentation, acute onset of severe headache, is similar to that in patients with other causes of SAH; however, severe neurological deficits (Hunt and Hess Grade IV and V SAH) have not been reported in SAH caused by cervical dAVFs. Patients with this type of SAH commonly report suboccipital headache, neck pain, and nausea, and thus these hemorrhages can be easily dismissed as perimesencephalic SAH. Vigilant evaluation with 4-vessel cerebral angiography, including selective catheterization of both proximal vertebral arteries, should be performed. The practice of unilateral vertebral artery injection with reflux into the contralateral vertebral and posterior inferior cerebellar arteries has the potential to overlook cervical dAVF. Magnetic resonance imaging may be useful to evaluate for other causes of SAH but is probably not sensitive for the identification of a cervical dAVF. Surgical treatment of this lesion has an excellent outcome.

We report a rare case of dissecting aneurysm of the distal anterior inferior cerebellar artery (AICA). A 63-year-old woman who complained of severe headache and nausea was admitted to our hospital. A computed tomography (CT) scan revealed subarachnoid hemorrhage, intraventricular hemorrhage, and acute hydrocephalus. Left vertebral angiogram revealed a dissecting aneurysm at the meatal loop of the distal AICA. On the next day, left suboccipital craniotomy was performed, and the fusiform aneurysm was trapped. The patient did not exhibit cranial nerve palsy after the operation. A left vertebral angiogram obtained after the operation showed that the dissecting aneurysm of the distal AICA had completely disappeared. Dissecting aneurysm of the distal AICA is a rare condition. Thus far, only 9 cases have been reported in the literature. We reviewed these cases and discussed the treatment for and outcome of dissecting aneurysms of the distal AICA.
