BACKGROUND: Spontaneous spinal and intracranial subdural hematomas are rarely reported, especially occurring simultaneously. Anticoagulation use has been associated with spontaneous hemorrhages. Prompt diagnosis is required to prevent permanent neurological sequelae. In this case report, we describe a spontaneous spinal and intracranial subdural hematoma in a woman taking warfarin and initially presenting with severe vaginal pain. CASE REPORT: A 42-year-old woman who had a history of mechanical valve replacement and was therefore taking warfarin, came to an emergency department for relief of severe vaginal pain...

Agenesis, aplasia and hypoplasia of the internal carotid artery are rare congenital malformations. They are usually asymptomatic and incidentally discovered through ultrasound or imagistic tests. The aim of this study is to improve their management in our Departments. We report here the case of a 39-year-old woman addressed to our ambulatory in 2013 for benign symptoms like dizziness and headache. Imagistic findings (magnetic resonance imaging of the brain, and cervical spine, and magnetic resonance angiography of the head and neck) indicated a very rare condition: left internal carotid artery agenesis accompanied by the absence of the pre-communicant part of the left anterior cerebral artery and of the right posterior communicating artery...

We report a case of spinal subarachnoid hemorrhage (SAH) caused by rupture of a mycotic anerurysm. A 59-year-old woman was admitted to our hospital with a sudden onset of headache and tetraparesis. Computed tomography (CT) scan of the brain revealed SAH, and magnetic resonance imaging (MRI) of the cervical spine showed an acute intradural hematoma. On angiogram, a saccular aneurysm was found on the C5 radiculomedullary artery, which arose from the left ascending cervical artery. Subsequently, her consciousness status deteriorated due to rebleeding, and she was brought to surgery...

Hanging is a common method of suicide that is being reported more frequently in many countries. Several complications including injuries to the cervical spine, neck vessels, and brain can occur after attempted suicide by hanging. There are only a few reports of brain computed tomography and magnetic resonance imaging of hanging victims. The most common abnormality was diffuse cerebral edema. A subarachnoid hemorrhage is an atypical complication by suicidal hanging. We report a case of a female patient who presented to an emergency department with altered mental status after attempting suicide by incomplete hanging...

OBJECT: Hemorrhagic origin is unidentifiable in 10%-20% of patients presenting with spontaneous subarachnoid hemorrhage (SAH). While the patients in such cases do well clinically, there is a lack of long-term angiographic followup. The authors of the present study evaluated the long-term clinical and angiographic follow-up of a patient cohort with SAH of unknown origin that had been enrolled in the Barrow Ruptured Aneurysm Trial (BRAT). METHODS: The BRAT database was searched for patients with SAH of unknown origin despite having undergone two or more angiographic studies as well as MRI of the brain and cervical spine...

BACKGROUND: Motor evoked potential (MEP) monitoring has been widely used in brain or spine surgery to recognize potential damage of the pyramidal motor system. However, its ability to detect ischemic injury during middle cerebral artery (MCA) aneurysm surgery remains unclear. A prospective cohort study was designed to evaluate MEP changes during MCA aneurysm surgery. METHODS: From January 2009 to August 2011, 89 patients underwent MCA aneurysm surgery and were prospectively divided into 2 groups: MEP monitoring group and control group...

Imaging of the skull base presents many challenges due to its anatomical complexity, numerous normal variants and lack of familiarity to many radiologists. As the skull base is a region which is not amenable to physical examination and as lesions of the skull base are generally difficult to biopsy and even more difficult to operate on, the radiologist plays a major role in directing patient management via accurate image interpretation. Knowledge of the skull base should not be limited to neuroradiologists and head and neck radiologists, however, as the central skull base is routinely included in the field of view when imaging the brain, cervical spine, or head and neck with computed tomography or magnetic resonance imaging, and hence, its nuances should be familiar to general radiologists as well...

Spontaneous thoracic spinal subarachnoid hemorrhage is rare, and thus no useful radiological findings for preoperative diagnosis have been reported. We experienced a patient with spontaneous thoracic spinal subarachnoid hemorrhage. A 37-year-old female presented with sudden-onset paraplegia and numbness in the trunk and bilateral lower extremities. The patient had no past history of trauma, lumbar puncture and bleeding disorder. T2-weighted sagittal magnetic resonance imaging (MRI) of the cervical and thoracic spines showed a mass occupied in the ventral space of spinal cord that was dorsally shifted...

Osteogenesis imperfecta is a rare genetic disorder that leads to progressive skeletal deformities due to deficits in type I collagen, the main pathophysiologic effect of the disease. In addition, it may lead to a wide range of associated neurologic abnormalities: The central nervous system is usually involved because of softening of bone at the base of the skull, with resultant upward migration of the upper cervical spine and odontoid process into the skull base. Upward migration of the spine may cause compression of the brainstem, mechanical impingement of the spinal canal with restriction of cerebrospinal fluid circulation, and impingement of the cranial nerves...
