Vestibular schwannomas (VS) are tumors originating from the eighth cranial nerve. The etiology and environmental risk factors for VS remain unclear. The goal of this study was to explore some potential environmental risk factors associated with vestibular schwannoma (VS). ⋯ The profile of patients with VS includes white race, age 50-60 years, either sex, and working in a professional occupation. Better access to health care and diagnostic imaging likely plays a role in the diagnosis of this tumor. Hay fever is strongly associated with VS. Tobacco use demonstrates an inverse relationship with VS, but the possible biologic mechanism for this is poorly understood, and tobacco remains a significant public health problem.

Atypical Teratoid Rhabdoid Tumor in a Teenager with Unusual Infiltration Into the Jugular Foramen.
Atypical teratoid rhabdoid tumor is a rare malignant neoplasm that represents 1%-2% of all pediatric central nervous system tumors. Immunohistochemistry plays an important role in establishing the diagnosis with a loss of INI-1 staining in tumor cells. In this case report, we describe a teenager with an unusual presentation and pattern of infiltration of the tumor. ⋯ This case highlights the diverse clinical presentation and infiltrative potential of atypical teratoid rhabdoid tumors, thus expanding the differential diagnosis of extra-axial tumors invading the jugular foramen.

In the pediatric population, awake craniotomy began to be used for the resection of brain tumor located close to eloquent areas. Some specificities must be taken into account to adapt this method to children. ⋯ Preoperative preparation and hypnosis in children seemed important for performing awake craniotomy and contributing language brain mapping with the best possible psychological experience. The pediatrics specificities are discussed.

Some studies demonstrated the role of steroids in medical management of chronic subdural hematoma (CSDH). Aim of our study is to evaluate the role of steroids in medical treatment of CSDH and to evaluate the subgroup of patients who respond to steroids. ⋯ Steroids appear to play a role in the nonsurgical medical treatment of CSDH. Patients with lower grades of CSDH can be treated successfully with steroids. Female patients seem to do better with steroids.
