In vestibular schwannoma surgery, the preservation of facial and cochlear nerves is of paramount concern regarding to their effect on patients' quality of life. The rate of nerve function preservation has increased with advancements in surgical technique and neuroimaging and the introduction of intraoperative neuromonitoring. The preoperative depiction of anatomical issues between the nerves and tumor could help in surgical planning. ⋯ The results from the present review have confirmed that preoperative fiber tracking for facial nerve identification during large vestibular schwannoma surgery is valuable and reliable. However, the included studies were not comparable in terms of images, acquisitions, or postprocessing elaboration. Larger series and homogenous magnetic resonance imaging parameters are required to strengthen these findings.

Review Case Reports
Grisel syndrome in pediatric age: an Italian single center experience and review of the literature.
Nontraumatic atlantoaxial subluxation, also known as Grisel syndrome, is a rare disease that usually affects children. The typical presentation is torticollis in patients with a history of surgical operations or airway infections. ⋯ Management of Grisel syndrome depends on the degree of subluxation basing on the Fielding and Hawkins classification. The initial nonsurgical management consists of close reduction and immobilization. Surgical fixation is indicated in cases of conservative treatment failure.

Review Case Reports
Deep Brain Stimulation of the Caudal Zona Incerta/Motor Thalamus for Post-Ischemic Dystonic Tremor of the Left Upper Limb. Case Report and Review of the Literature.
Dystonic tremor is defined as a tremor occurring in a body region affected by dystonia. The pathophysiologic mechanisms behind dystonic tremor supposedly involve anomalies affecting the pallidothalamic-receiving area (for the dystonic component) and the ventralis intermedius-cortical loop (for the tremor component). Interest in posterior subthalamic area stimulation for various types of involuntary abnormal movements has arisen owing to positive results in patients affected by tremor refractory to ventralis intermedius deep brain stimulation. ⋯ Stimulation of motor thalamus and caudal zona incerta could be a viable treatment for patients affected by tremor of various origins, including dystonic tremor, refractory to medical therapy.

Review Case Reports
"Intramedullary capillary hemangioma presenting with hydrocephalus and spastic paraparesis in a two-month-old infant".
Intramedullary capillary hemangiomas are rare lesions with only 14 cases reported so far and are found in middle-aged persons. Until now only a single case has been reported in the pediatric population. Ours was the second pediatric case and the youngest of all to be diagnosed with an intramedullary capillary hemangioma. ⋯ Intramedullary capillary hemangiomas are extremely rare lesions in infants but should be kept in mind while treating any patient with the spinal lesion. Further reporting of similar cases will help in understanding the natural history, pathogenesis, and management.

Review Case Reports
Intracranial inflammatory myofibroblastic tumor with negative expression of anaplastic lymphoma kinase: a case report and review of the literature.
Inflammatory myofibroblastic tumor (IMT) is an indolent tumor mainly affecting children and young adults. As a rare mesenchymal tumor with unknown etiology and pathogenesis, IMT has a predilection for the lung and abdominopelvic region. Previous literature featuring IMT in the central nervous system (IMT-CNS) is rare. The clinical symptoms and radiologic features of IMT-CNS are not specific; therefore, the diagnosis is predominately based on the histopathologic and immunohistochemical analysis of the specimen. ⋯ Remission of her symptoms was observed, and no recurrence was recorded during a 6-month follow-up.
