Of all brain metastases, the most common primary lesion is derived from the lung. These types of metastases enlarge aggressively with unfavorable prognoses. We report the case of a 75-year-old male patient who had a history of pulmonary resection for Stage IA non-small cell lung cancer(NSCLC), and received chemotherapy. One year after NSCLC surgery, he experienced a cardiogenic cerebral infarction, and anticoagulant therapy was initiated. Mass lesions with hemorrhage were detected bilaterally in the frontal lobes through magnetic resonance imaging three years after the NSCLC surgery...

OBJECTIVE Although reoperation and readmission have been used as quality metrics, there are limited data evaluating the rate of, reasons for, and predictors of reoperation and readmission after microsurgical clipping of unruptured aneurysms. METHODS Adult patients who underwent craniotomy for clipping of an unruptured aneurysm electively were extracted from the prospective National Surgical Quality Improvement Program registry (2011-2014). Multivariable logistic regression and recursive partitioning analysis evaluated the independent predictors of nonroutine hospital discharge, unplanned 30-day reoperation, and readmission...

BACKGROUND: Cerebral hyperperfusion sometimes occurs after removal of chronic subdural hematoma (CSH) and usually resolves within a few days without any symptoms. Subcortical low intensity (SCLI) on fluid attenuated inversion recovery (FLAIR) magnetic resonance images is rare and has been reported in some diseases other than CSH. The authors describe a case of organized CSH who suffered prolonged neurologic deterioration, SCLI and cerebral hyperperfusion postoperatively. CASE DESCRIPTION: An 81-year-old man, presenting with left hemiparesis, underwent craniotomy for right organized CSH after 2-time burr-hole surgeries...

Background Pressure on economic resources now requires a careful rationalization of services. For adult patients with supratentorial gliomas, there is no consensus on the real need for care in a postoperative neurocritical intensive care unit (NICU) and on the timing of a postsurgical computed tomography (CT) scan. In this retrospective nonrandomized study, we assessed if and when there is a real need for NICU and if an early CT scan could be justified in the absence of neurologic worsening. Methods Of 264 patients, 21 were admitted to the NICU after the procedure as planned before the surgery for their clinical features (Karnofsky performance status < 70, American Society of Anesthesiologists score > 2, or Charlson Comorbidity Index > 5)...

BACKGROUND: Malpractice claims that arise during the perioperative care of patients receiving orthopaedic procedures will frequently involve both orthopaedic surgeons and anesthesiologists. The Anesthesia Closed Claims database contains anesthesia malpractice claim data that can be used to investigate patient safety events arising during the care of orthopaedic patients and can provide insight into the medicolegal liability shared by the two specialties. QUESTIONS/PURPOSES: (1) How do orthopaedic anesthetic malpractice claims differ from other anesthesia claims with regard to patient and case characteristics, common events and injuries, and liability profile? (2) What are the characteristics of patients who had neuraxial hematomas after spinal and epidural anesthesia for orthopaedic procedures? (3) What are the characteristics of patients who had orthopaedic anesthesia malpractice claims for central ischemic neurologic injury occurring during shoulder surgery in the beach chair position? (4) What are the characteristics of patients who had malpractice claims for respiratory depression and respiratory arrests in the postoperative period? METHODS: The Anesthesia Closed Claims Project database was the source of data for this study...

A true collision tumor is a rare entity composed of two histologically distinct neoplasms coinciding in the same organ. This paper reports a unique case of cerebral collision tumor consisting of two benign components. On the first hand, meningioma which is usually a benign lesion arising from the meningothelial cell in the arachnoidal membrane. On the other, cerebral cavernoma which is a well-circumscribed, benign vascular hamartoma within the brain. To our knowledge, there is no previously documented case of cerebral collision tumor consisting of two benign components...

BACKGROUND: Convexity meningiomas are benign brain tumors that are amenable to complete surgical resection and are associated with a low complication rate. The aim of this study was to identify factors that result in acute postoperative neurological worsening after the removal of convexity meningiomas. METHODS: Clinical evaluation and neuroradiological analysis of patients who underwent removal of a supratentorial convexity meningioma were reviewed. Patients were selected when their postoperative course was complicated by acute neurological deterioration requiring decompressive craniectomy...

Although the microvascular decompression (MVD) surgery has become an effective remedy for cranial nerve rhizopathies, it is still challengeable and may result in a fatal sequel sometimes. Therefore, the operative skill needs to be further highlighted with emphasis on the safety and a preplan for management of postoperative fatal complications should be established. We retrospectively analyzed 6974 cases of MVD. Postoperatively, 46 patients (0.66 %) presented decline in consciousness with a positive finger-nose test (or failure to be tested) after wake up from the anesthesia, whom were focused on in this study...

OBJECTIVE Endoscopic removal of intracerebral hematomas is becoming increasingly common, but there is no standard technique. The authors explored the use of a simple image-guided endoscopic method for removal of spontaneous supratentorial hematomas. METHODS Virtual reality technology based on a hospital picture archiving and communications systems (PACS) was used in 3D hematoma visualization and surgical planning. Augmented reality based on an Android smartphone app, Sina neurosurgical assist, allowed a projection of the hematoma to be seen on the patient's scalp to facilitate selection of the best trajectory to the center of the hematoma...

INTRODUCTION: Developmental venous anomalies (DVAs) are cited as the most common cerebral vascular malformations. Still, intracerebral hematomas are rarely thought to be caused by DVAs. In this report, the authors present a unique case of a DVA that hemorrhaged spontaneously, rather than hemorrhaging into a venous infarction following DVA thrombosis as has been more commonly reported. CLINICAL PRESENTATION: A 22-year-old previously healthy male presented to the emergency department with a severe headache, confusion, and progressive hemiparesis...
