Microscopic biopsy after unsuccessful endoscopic biopsy for primary central nervous system lymphoma of the corpus callosum: A case report.

Introduction And Importance: Primary central nervous system lymphoma (PCNSL) is a rare tumor with a poor prognosis. Early brain biopsy is essential to avoid a diagnostic delay. To date, reports of successful diagnosis for PCNSL of the corpus callosum by endoscopic biopsy are rare.

Idiopathic unilateral oculomotor nerve palsy: A case report.

Cranial nerve III palsy, also known as oculomotor nerve palsy, may result from various causes; however, the etiology remains unknown in some instances. The aim of this case report is to present the authors' experience with two cases of idiopathic cranial nerve III palsy, together with a review of the literature. Case 1 is a 78-year-old woman and case 2 is a 75-year-old man, both having no history of trauma and no vascular risk factors.

Frontotemporal epi- and subdural approach to a cavernous sinus tumor for sphenobasal vein preservation--technical case report.

In cavernous sinus (CS) surgery, venous complication may occur in some types of venous drainage. The sphenobasal vein (SBV) drains from the superficial middle cerebral vein (SMCV) to the pterygoid venous plexus at the temporal skull base. A frontotemporal epi- and interdural approach (Dolenc approach), which is one of the CS approaches, may damage the SBV's route.

Subarachnoid hemorrhage causing cardiopulmonary arrest: resuscitation profiles and outcomes.

Aneurysmal subarachnoid hemorrhage (SAH) is a common cause of cardiopulmonary arrest (CPA). The outcomes of SAH patients presenting with CPA are extremely poor, and long-term survivors have occasionally been reported, but the circumstances under which SAH-CPA patients achieve long-term survival are unclear. Neurosurgeons will have to determine whether a SAH-CPA patient is brain-dead or not more often after enactment of the revised Organ Transplantation Act.

Spontaneous intracranial hypotension presenting without orthostatic headache complicated by acute subdural hematoma after drainage for chronic subdural hematoma--case report.

A 28-year-old man presented with a case of spontaneous intracranial hypotension (SIH) manifesting as a bilateral chronic subdural hematoma (CSDH) without orthostatic headache. He developed life-threatening acute SDH as a complication of CSDH drainage. Neurosurgeons should be aware that SIH patients do not always present with orthostatic headache.

Influence of age and anti-platelet/anti-coagulant use on the outcome of elderly patients with fall-related traumatic intracranial hemorrhage.

Ground-level fall is the most common cause of traumatic intracranial hemorrhage (TICH) in the elderly. Many studies on geriatric TICH have regarded patients aged ≥65 years as a single group, but substantial heterogeneity is likely to exist within this population. Eighty-two elderly patients with fall-related TICH treated in our institution during a 6-year period were stratified into 3 age groups (65-74, 75-84, and ≥85 years), and intergroup differences in the demographics and outcomes at discharge were evaluated.

Fulminant ependymitis following intraventricular rupture of brain abscess.

A 48-year-old man with a history of a penetrating brain injury was referred with a presumptive diagnosis of bacterial meningitis. Examination revealed a brain abscess in addition to meningitis. Blood and cerebrospinal fluid (CSF) cultures were negative for bacteria, and empirical IV antibiotic therapy with vancomycin (VCM) and meropenem was initiated.

Gliomatosis cerebri mimicking chemotherapy-induced leukoencephalopathy in a patient with non-Hodgkin's lymphoma.

Patients with hematological malignancies may develop white matter lesions, which are usually associated with chemotherapy. Magnetic resonance imaging (MRI) is the imaging modality of choice for identifying chemotherapy-induced, or "toxic", leukoencephalopathy. Brain biopsy in patients with hematological malignancies suspected of sustaining toxic leukoencephalopathy has rarely been performed, because its characteristic MRI findings are considered pathognomotic.

Ultrasound-guided needle aspiration of epidural hematoma in a neonate after vacuum-assisted delivery.

Introduction: Epidural hematoma (EDH) is a rare complication of vacuum-assisted delivery in neonates. Although the standard treatment of EDH is surgical evacuation via craniotomy, it is an invasive procedure in neonates, and less invasive methods may be favored for hematoma evacuation.

Case Report: We report a case of 5-day-old infant with a massive EDH, cephalohematoma, and a depressed fracture, which were secondary to a vacuum-assisted delivery and cured by ultrasound-guided needle aspiration and drainage.

Does difference in the storage method of bone flaps after decompressive craniectomy affect the incidence of surgical site infection after cranioplasty? Comparison between subcutaneous pocket and cryopreservation.

Background: After decompressive craniectomy for brain swelling, bone flaps need to be stored in a sterile fashion until cranioplasty. Temporary placement in a subcutaneous pocket (SP) and cryopreservation (CP) are the two commonly used methods for preserving bone flaps. Surgical site infection (SSI) is a serious complication of cranioplasty, and the storage method associated with a lower SSI incidence is favored.

Glioblastoma masquerading as a hypertensive putaminal hemorrhage: a diagnostic pitfall.

A 58-year-old man presented with a rare case of glioblastoma masquerading as intracerebral hemorrhage (ICH). He had been medicated for hypertension and diabetes for 10 years before collapsing at home. Brain computed tomography (CT) showed ICH in the right putamen, but CT with contrast medium showed no underlying lesion.

Tension pneumocephalus as a complication of lumbar drainage for cerebral aneurysm surgery--case report.

A 66-year-old man developed tension pneumocephalus after failed lumbar drainage before clipping surgery for a ruptured anterior communicating artery aneurysm. After puncture with a Tuohy needle, the spinal catheter could not be inserted into the spinal dura, so surgery proceeded without the catheter placement. The patient's neurological status deteriorated suddenly into coma within 15 hours after uneventful clipping of the aneurysm.
