Purpose Of The Study: To assess the role of monitoring of intracranial pressure (ICP) in patients with massive ischemic stroke within the first 5 days of the onset of the disease.
Material And Methods: We have analyzed the results of monitoring of intracranial pressure in 10 patients with massive ischemic stroke and compared dynamics of ICP with the dynamics of intracranial pressure and the level of consciousness and dislocation of the brain according to CT RESULTS: Dislocation syndrome decompensation occurred in 6 patients, of which only 3 patients had increased intracranial pressure greater than 20 mm Hg with oppression of the level of consciousness to moderate coma and deeper The average value of transverse dislocation in these patients at the same time amounted to 17 mm. In 2 patients with atrophy of the brain we observed ICP increase over 20 mmHg. The average value of transverse dislocation in these patients was 12 mm. Conclusion: Increased intracranial pressure greater than 20 mm Hg in patients with massive ischemic stroke can occur even when the oppression of the level of consciousness to moderate coma and deeper on the background of the dislocation of the brain. In case of an atrophy of the brain, the level of ICP may not exceed 20 mm Hg even with dislocation syndrome decompensation.

Background And Purpose: In idiopathic normal pressure hydrocephalus (iNPH) patients, cerebrospinal fluid (CSF) flow is typically evaluated with a cardiac-gated two-dimensional (2D) phase-contrast (PC) MRI through the cerebral aqueduct. This approach is limited by the evaluation of a single location and does not account for respiration effects on flow. In this study, we quantified the cardiac and respiratory contributions to CSF movement at multiple intracranial locations using a real-time 2D PC-MRI and evaluated the diagnostic value of CSF dynamics biomarkers in classifying iNPH patients.

Prompt emergence from general anesthesia is crucial after neurosurgical procedures, such as craniotomies, to facilitate timely neurological evaluation for identification of intraoperative complications. Delayed emergence can be caused by residual anesthetics, metabolic imbalances, and intracranial pathology, for which an eye examination can provide early diagnostic clues. The sunset sign (or setting sun sign), characterized by a downward deviation of the eyes, can be an early indicator of raised intracranial pressure (ICP) or midbrain compression, as is commonly observed in states of hydrocephalus or periaqueductal or tectal plate dysfunction.

Background: Entropy quantifies the level of disorder within a system. Low entropy reflects increased rigidity of homeostatic feedback systems possibly reflecting failure of protective physiological mechanisms like cerebral autoregulation. In traumatic brain injury (TBI), low entropy of heart rate and intracranial pressure (ICP) predict unfavorable outcome.

Intracerebral hemorrhage (ICH) presents complex clinical challenges, particularly in patients receiving anticoagulation therapy. This case report discusses the management of acute ICH in a 60-year-old male patient on long-term apixaban therapy, who arrived at the emergency department with altered consciousness, right-sided hemiplegia, and mixed aphasia. Computed tomography (CT) imaging revealed a 70 ml left lenticular-capsular hematoma with significant mass effect, necessitating rapid intervention.

Intracranial epidermoid cyst (EC) is a slow-growing, benign lesion that rarely undergoes a malignant transformation. When it does occur, the clinical course is aggressive. Certain radiological criteria may give a clue to diagnosis and help in deciding the appropriate course of action as well as prognostication.
