Characteristics and outcomes of large artery occlusion-related stroke due to intracranial atherostenosis: An experience from a single center in Saudi Arabia.

Background: Literature on the frequency, response to treatment, and outcomes of acute ischemic stroke (AIS) due to intracranial atherostenosis (ICAS)-related intracranial large artery occlusion (ILAO) from Saudi Arabia is scarce. The aim of this study was to identify the percentage, describe the characteristics, and observe the treatment response in patients with AIS attributed to ICAS-related ILAO.

Materials And Methods: This cross-sectional study included all adult patients from 2017-2021 who fulfilled the inclusion criteria for the diagnosis of ICAS-related AIS.

Prevalence and Clinico-Radiologic Spectrum of Intracranial Atherosclerotic Disease-Related Stroke: An Observation from a Single Center in Saudi Arabia.

Background: Intracranial atherosclerotic disease (ICAD) is an important etiologic subtype of acute ischemic stroke (AIS). However, little direct evidence is available regarding ICAD-related stroke in Saudi Arabia (SA). This study aimed to identify the prevalence and describe the clinico-radiological spectrum of ICAD-related AIS in a SA cohort.

Pediatric Stroke from Bench to Bedside: A Single-Center Experience in Saudi Arabia.

Purpose: Stroke is a leading cause of severe long-term disability and death worldwide. This study aimed to determine the genetic background, causative factors, and diagnostic and outcome measures of pediatric stroke in an area endemic to sickle cell disease (SCD).

Patients And Methods: This retrospective review analyzed pediatric patients with acute stroke who were admitted to King Fahd Hospital of the University, Eastern Province, Saudi Arabia, between January and June 2019.

Posterior fossa extra-axial variations of medulloblastoma: a pictorial review as a primer for radiologists.

Manifestations of an atypical variant of medulloblastoma of the posterior fossa in extra-axial locations have been reported, and key questions concerning its interpretation have been raised previously. This review illustrated the clinico-radiological and histopathological features of the posterior fossa extra-axial medulloblastoma and described possible management strategies. We thoroughly reviewed all atypical anatomical locations of medulloblastoma reported within the posterior fossa and extra-axial spaces.

A 37-Year-Old Saudi Man with a Calcified Intraventricular Astrocytoma.

BACKGROUND Pilocytic astrocytoma is a low-grade glioma that is common in children. Pilocytic astrocytoma is a slow-growing neoplasm that may calcify and occurs throughout the central nervous system, but it has a preference to be located infratentorial in children. CASE REPORT Herein, we report an unusual intraventricular location of pilocytic astrocytoma with extensive calcification in a 37-year-old Saudi man who mainly presented with a headache.

Spinal anastomosed remnant imprints of vertebral veins linking the transverse foramina: a case report of a novel anatomic variant of the cervical venous plexus.

Purpose: Despite various postulated classifications attempting to simplify the complex angioarchitecture of the cervical spine, the nomenclature of spinal variants and lesions remains inconsistent. Knowledge of variations in the anatomy of the vertebral veins will assist in avoiding complications during neck surgery and procedures such as vertebroplasty. In addition, venous variants may act as a route for the spread of infection, emboli, or metastases.

Rates of cerebrospinal fluid infection and the causative organisms following shunt procedures in Saudi Arabia. A retrospective study based on radiological findings.

To assess the incidence of infection following various cerebrospinal fluid (CSF) shunt procedures among patients with hydrocephalus and related conditions, based on the age of the patient, and to determine the types of pathogens responsible for shunt infections. Methods: This retrospective single center study reviewed the records of patients with culture-confirmed CSF shunt infection diagnosed between January 2012 and December 2017. Cases without central nervous system imaging investigations were excluded.

A ruptured posterior communicating artery aneurysm presenting as tentorial and spinal isolated subdural hemorrhage: a case report and literature review.

Background: Ruptured intracranial aneurysms are often associated with subarachnoid or intraparenchymal hemorrhage. However, the prevalence of subdural hemorrhage post aneurysmal rupture is low and rarely reported in scientific studies. Here, we report an unusual case of a ruptured posterior communicating artery aneurysm resulting in an isolated subdural hematoma located in the tentorial and spinal canal without subarachnoid or intraparenchymal hemorrhage.

Primary pigmented meningeal melanocytoma originating in Meckel cave in a patient with carney complex: A case report.

Rationale: Primary melanin-producing tumors are rare extra-axial neoplasms OPEN of the central nervous system. In the literature, few case reports have discussed neoplasms involving the cavernous sinus; of these, only 4 have reported on neoplasms originating in Meckel cave. The diagnostic approach, including clinical and radiological analysis, is challenging, and cytopathological assessment with a molecular basis is the best approach to discriminate between these lesions.

Neuroschistosomiasis mimicking lower back pain: case report of a rare differential diagnosis in a pediatric patient.

Background: Spinal myelitis is an infrequent manifestation of spinal cord infection. It is caused by the species, which are endemic in South America, part of the Middle East, and Africa.

Case Presentation: We report the case of a 13-year-old male adolescent complaining of progressive lower back pain and weakness of the lower extremities for 3 days.

A unique finding of cavum velum interpositum colloid-like cyst and literature review of a commonplace lesion in an uncommon place.

Colloid cysts typically reside within the area of the anterior third ventricle, in the proximity of the foramen of Monro. Although they are considered to commonly localize in various parts of the cerebrum, they are exceedingly rare outside the ventricular system and rarely occur within the velum interpositum. We have reported here a rare case of a velum interpositum colloid-like cyst in a 23-year-old man, who presented to our clinic with temporary binocular strabismus, which he had been experiencing for the previous year.

An Atypical Porencephalic Cyst Manifesting as a Simple Partial Seizure: A Case Report and Literature Review.

Background: Porencephaly is an extremely rare neurological disease characterized by the presence of solitary or multiple degenerative cerebrospinal fluid (CSF) cavities within the brain parenchyma.

Case Report: We describe a case involving a 23-year-old male who presented with involuntary movements of the left upper limb of 6 months' duration. A diagnosis of porencephaly was confirmed by magnetic resonance imaging (MRI).
