Review Case Reports
Adult-onset mixed germ cell tumor composed mainly of yolk sac tumor around the pineal gland: a case report and review of the literature.
Mixed germ cell tumors (MGCTs) usually occur in children. In the present report, we discuss an extremely rare case of adult-onset MGCT composed mainly of yolk sac tumor (YST) around the pineal gland. ⋯ The present case highlights the need for clinicians to include YST in the differential diagnosis of acute progressive lesions around the pineal region, even in adult patients.

Transnasal and Transoral Approaches to Atlantoaxial Synovial Cysts: Report of 3 Cases and Review of the Literature.
Synovial cysts are cystic masses lined with pseudostratified columnar cells and containing clear or xanthochromic fluid. Although they are commonly encountered in the lumbar spine, synovial cysts infrequently occur in the cervical spine and rarely involve the odontoid process. The causes of synovial cysts of the odontoid process are unknown, but growth of synovial rests, proliferation of multipotent mesenchymal cells, atlantoaxial instability, and trauma are thought to play a role. ⋯ Tissue diagnosis is important in confirming pathologic analysis because synovial cysts have radiographic characteristics similar to those of a wide variety of neoplasms of the craniovertebral junction.

Review Case Reports
Intracranial multiple pseudotumor due to immunoglobulin G4-related disease without other lesion: case report and literature review.
Immunoglobulin (Ig)G4-related disease (IgG4-RD) was defined only recently and can be found in many organs. As intracranial lesions, hypophysitis and pachymeningitis are well known, whereas intracranial pseudotumor is unusual. This case involved multiple intracranial pseudotumors without extracranial lesions, mimicking multiple meningioma. ⋯ This case demonstrates IgG4-RD mimicking meningioma with multiple masses but without extracranial lesions. This case and previous descriptions suggest the possibility of pseudotumor due to IgG4-RD in the presence of multiple extra-axial lesions at the dura and supplying artery, hard nodules with thickening of the artery, and frozen section findings of lymphoplasmacytes surrounded by rich collagen fibers. In such cases, the pseudotumor due to IgG4-RD should be resected, and total resection might not be warranted.

Intracranial hemorrhage (ICH) is a common complication in patients with left ventricular assist devices (LVADs) and carries a dismal prognosis. Limited data are available on the management and outcomes in this population, which are essential to determine an optimal treatment strategy. We conducted a systematic literature review to determine the clinical characteristics and survival of this population. ⋯ There is minimal existing literature on patients with LVAD with ICH that report patient outcomes in a nonstandardized fashion. The studies included in this analysis report mortality consistent with previous reports, indicating a need for further investigation to identify risk factors and improve outcomes in these patients.

Re-Resection And Intraoperative Radiotherapy For Malignant Gliomas Of The Brain: A History And Review Of Current Techniques.
The degree of primary resection of malignant brain gliomas (MBGs) has correlated positively with progression-free and overall survival. The indications for surgery and reoperation in MBG relapse remain controversial. ⋯ We reviewed the reported studies with respect to repeat resection and the various methods of intraoperative radiotherapy for MBGs from the initial experience with high-energy linear accelerators in Japan to modern, integrated brachytherapy solutions using solid and balloon applicators. Because of the findings from our review, we have begun to research into the use of intraoperative balloon brachytherapy for recurrent MBGs.
