Spontaneous Spinal Subarachnoid Hemorrhage: Presentation and Outcome
Spontaneous spinal subarachnoid hemorrhage (SSAH) is a rare but serious condition that can lead to a variety of medical complications.

Therapeutically Targeting Platelet-Derived Growth Factor-Mediated Signaling Underlying the Pathogenesis of Subarachnoid Hemorrhage-Related Vasospasm
Vasospasm accounts for a large fraction of the morbidity and mortality burden in patients sustaining subarachnoid hemorrhage (SAH). Platelet-derived growth factor (PDGF)- β levels rise following SAH and correlate with incidence and severity of vasospasm.

Coil Embolization through Collateral Pathway for Ruptured Vertebral Artery Dissecting Aneurysm with Bilateral Vertebral Artery Occlusion
Intracranial vertebral artery dissecting aneurysm (VADA) is a well-known cause of subarachnoid hemorrhage (SAH). Endovascular treatment is now well established as an effective method for treating ruptured VADA, especially in the acute phase of SAH.1,2 Although stent technology has introduced a new strategy in the treatment of VADA, internal trapping of both the affected vertebral artery (VA) and the VADA using detachable coils is still the standard endovascular treatment for the acute phase of ruptured VADAs to prevent re-rupture.

Nonaneurysmal “Pseudo-Subarachnoid Hemorrhage” Computed Tomography Patterns: Challenges in an Acute Decision-Making Heuristics
Acute aneurysmal subarachnoid hemorrhage (SAH) is a medical and neurosurgical emergency from ruptured brain aneurysm. Aneurysmal SAH is identified on brain computed tomography (CT) as increased density of basal cisterns and subarachnoid spaces from acute blood products. Aneurysmal SAH-like pattern on CT appears as an optical illusion effect of hypodense brain parenchyma and/or hyperdense surrounding cerebral cisterns and blood vessels termed as “pseudo-subarachnoid hemorrhage” (pseudo-SAH).

Acute Intracranial and Spinal Subdural Hematoma Associated with Vardenafil
A 28-year-old healthy man was admitted to our hospital because of right-sided headache, vomiting, and lower back pain after the administration of vardenafil. Computed tomography and magnetic resonance imaging of the brain showed a small, right-sided, subdural hematoma. A lumbar magnetic resonance imaging showed a longitudinally extended subdural hematoma. He had no history of trauma. We speculated that vardenafil might have had an association with the bleeding. Several reports have suggested a relationship between phosphodiesterase-5 inhibitors and intracerebral or subarachnoid hemorrhage.

Spinal Dural Arteriovenous Fistula Assumed to be Symptomatic after Placement of Lumbar Cerebrospinal Fluid Drain
A 69-year-old man presented with severe headache. Cranial computed tomography revealed diffuse subarachnoid hemorrhage. An anterior communicating artery aneurysm was identified and successfully obliterated by open microsurgery on the same day. Following placement of a continuous lumbar cerebrospinal fluid drain on hospitalization day 7, the patient developed a severe paraplegia and sensory loss below T6. Cerebral magnetic resonance imaging did not identify a responsible lesion. Spinal magnetic resonance imaging, however, showed extensive intramedullary hyperintensity on T2-weighted sequences.

Lacunar Stroke, Cavernous Angioma, and Fusiform Aneurysm Due to Irradiation for Pilocytic Astrocytoma —A Case Report
We describe a rare case of a pediatric patient who presented multiple different types of vascular events consecutively in the irradiated field including lacunar stroke because of occlusion of perforating artery, intraventricular hemorrhage from cavernoma, and subarachnoid hemorrhage because of the rupture of fusiform aneurysm, 6 years after radiotherapy against pilocytic astrocytoma.

Spinal Cord Hemorrhage
Spinal cord hemorrhages are rare conditions that can be classified based on the primary location of bleeding into intramedullary (hematomyelia), subarachnoid hemorrhage (SAH), subdural hemorrhage, and epidural hemorrhage. We conducted a literature review to better understand the presenting symptoms, etiology, diagnosis, and treatment of spinal cord hemorrhages.

Hyperperfusion after Clipping of Aneurysm: A Rare Entity
Cerebral vasospasm is an uncontrollable and sometimes fatal complication occurring after subarachnoid hemorrhage. However, cerebral hyperperfusion syndrome is a rare complication after subarachnoid hemorrhage. Although plain computed tomography of cerebral hyperperfusion syndrome looks similar to cerebral infarction induced by cerebral vasospasm, they should be distinguished from each other because they require completely different treatments.
