The safety and efficacy of double microcatheter technique in small and tiny ruptured aneurysms: A single center study.

Objective: Double microcatheter technique (dMC) can be the alternative to Single microcatheter technique (sMC) for challenging cases, but there is lack of studies comparing dMC to sMC especifically for small ruptured aneurysms. Our objective was to compare the safety and efficacy of dMC to sMC in treating small (≤5 mm) and tiny (≤3 mm) ruptured aneurysms.

Methods: This study focused on 91 out of 280 patients who had ruptured aneurysms and underwent either single or double microcatheter coil embolization.

Pituitary Neuroendocrine Tumor: Is It Benign or Malignant?

The World Health Organization (WHO) updated the classification of pituitary tumors in 2022. The new classification presents detailed histological subtyping of a pituitary neuroendocrine tumor (PitNET) based on the tumor cell lineage, cell type, and related characteristics. The immunohistochemistry for pituitary transcription factors (PIT1, TPIT, SF1, GATA3, and ERα) is routinely needed in this classification.

Metaplastic Meningioma Overspreading the Cerebral Convexity.

Meningioma is relatively common, benign, and extra-axial tumor accounting for about 20% of primary brain and spinal cord tumors. The World Health Organization (WHO) classified these tumors into Grade I (benign), Grade II (atypical), and Grade III (anaplastic) meningioma. Grade I meningioma which is slowly growing tumor and have some rare subtypes.

The Prevalence and Characterization of Cerebral Microbleeds in Young People Having Intracerebral Hemorrhage.

Objective: Cerebral microbleeds (CMBs) are known as the neuroimaging markers of risk in stroke and dementia. Many studies on CMBs in elderly patients with hemorrhagic or ischemic stroke have been reported; however, reports on CMBs in young populations with intracerebral hemorrhage (ICH) are lacking.

Materials And Methods: A total of 272 patients aged 18-54 years presented to our hospital with ICH between December 2009 and August 2017.

Phenytoin versus levetiracetam as prophylaxis for postcraniotomy seizure in patients with no history of seizures: systematic review and meta-analysis.

OBJECTIVEDe novo seizure following craniotomy (DSC) for nontraumatic pathology may adversely affect medical and neurological outcomes in patients with no history of seizures who have undergone craniotomies. Antiepileptic drugs (AEDs) are commonly used prophylactically in patients undergoing craniotomy; however, evidence supporting this practice is limited and mixed. The authors aimed to collate the available evidence on the efficacy and tolerability of levetiracetam monotherapy and compare it with that of the classic AED, phenytoin, for DSC.

Objective: To evaluate the effectiveness and efficacy of delayed burr hole surgery in relation to the reduction of postoperative subdural hematoma (SDH) volume in patients with acute SDH.

Methods: We retrospectively analyzed patients with acute SDH who received delayed burr hole surgery at our institute. Age, sex, Glasgow coma scale, maximal SDH thickness, volume of SDH, midline shifts, hounsfield unit (HU), and medical history of anticoagulant agent usage were recorded.

Efficacy of pulsed radiofrequency medial branch treatment in low back pain patients.

Background: It was thought that the efficacy of pulsed radiofrequency (PRF) treatment of the medial branch in patients with lower back pain was not as long lasting as that of continuous radiofrequency (CRF) thermo-coagulation techniques.

Objective: The goal of this study was to determine the efficacy and the long-term effects of PRF treatment of the medial branch in selected low back pain patients.

Methods: We retrospectively reviewed and analyzed patients with lower back pain who underwent PRF treatment on the medial branch at our institute.

Are There Differences in the Progression of Ossification of the Posterior Longitudinal Ligament Following Laminoplasty Versus Fusion?: A Meta-Analysis.

Study Design: Systematic review and meta-analysis of studies for the treatment of cervical myelopathy with ossification of the posterior longitudinal ligament (OPLL) treated with laminoplasty or fusion.

Objective: To delineate whether OPLL continues to progress after laminoplasty compared with fusion and to clarify the relationship between radiological progression of OPLL and neurological decline.

Summary Of Background Data: Laminoplasty is usually performed in patients with multilevel OPLL due to the surgical morbidity of anterior surgery.

Primary Intracranial Leptomeningeal Melanomatosis.

Primary intracranial malignant melanoma is a very rare and highly aggressive tumor with poor prognosis. A 66-year-old female patient presented a headache that had been slowly progressing for several months. A large benign pigmented skin lesion was found on her back.

The efficacy of pulsed radiofrequency treatment of cervical radicular pain patients.

Objective: Cervical radicular pain is defined as pain arising in the arm caused by irritation of a cervical spinal nerve or its roots. Although many treatment modalities are described in the literature, the available evidence for efficacy is not sufficient to allow definitive conclusions. The goal of this study was to establish the benefits and prognostic factors of pulsed radiofrequency (PRF) on the adjacent cervical dorsal root ganglia (DRG) of cervical radicular pain patients.

Spontaneously rapid resolution of acute subdural hemorrhage with severe midline shift.

Acute subdural hematoma is usually a neurological emergency that requires hematoma evacuation or close observation. However, spontaneous resolutions of an acute subdural hematoma without surgical interventions have been reported rarely. We report on a case who showed rapid resolution of an acute subdural hematoma with neurological improvement and review the relevant literatures.

Lymphomatosis cerebri.

Lymphomatosis cerebri is considered a diffuse form of primary central nervous system lymphoma and very rare. It is not well recognized and may be misdiagnosed with infiltrating tumors, degenerative disorders, ischemic diseases, and infectious diseases developed in the brain. Awareness of the possibility of this rare disease and early biopsy are required for differential diagnosis and preventing poor clinical outcomes.

Primary intracranial ectopic craniopharyngioma in a patient with probable Gardner's syndrome.

The authors describe a patient with an adamantinomatous craniopharyngioma (CPG) arising in the cerebellopontine angle (CPA), who also had probable Gardner's syndrome. This 31-year-old man presented with headache and dizziness. Brain CT and MRI showed a 5 × 4-cm lesion with multiple small calcifications in the left CPA.
