Cerebrospinal fluid (CSF) leakage is one of the most challenging complications in neurosurgery. We sought to evaluate the efficacy of dural sealants in preventing CSF leakage after cranial surgery. ⋯ This systematic review showed that dural sealants did not reduce the number of CSF leaks in general, the number of incisional CSF leaks alone, or the number of pseudomeningocele formations alone. However, dural sealants reduced the risk of surgical-site infection.

Review Case Reports
Distinguishing Falcine Chondrosarcomas from Their Mimics and Management.
Primary intracranial chondrosarcoma is an extremely rare malignant tumor of the central nervous system, which accounts for <0.16% of all primary intracranial tumors. This rare tumor has a high associated morbidity from the tumor itself as well as from treatment modalities. ⋯ Dural chondrosarcoma is a possible entity in the differential diagnosis of a presumed meningioma, particularly when atypical features are present. We report a grade 1 intracranial chondrosarcoma of the classical subtype without any neurologic problems after complete surgical excision. The patient did not receive any adjuvant therapy and at 26 months' follow-up showed no recurrence.

Review Case Reports
Embolization of Ruptured Distal Lenticulostriate Artery Aneurysms.
To describe the critical role of endovascular treatment and safety for the patients who presented with intraventricular hemorrhage owing to rupture of the distal lenticulostriate artery aneurysms. ⋯ Endovascular therapy is available and safe as a treatment option for distal lateral lenticulostriate artery aneurysms.

Treatment of Partially Thrombosed Intracranial Aneurysms: Single-Center Series and Systematic Review.
Partially thrombosed intracranial aneurysms (PTIAs) represent a challenging subgroup of aneurysms, with an organized intraluminal thrombus and a solid mass, in which the optimal therapeutic strategy is discussed controversially because of limited data. We therefore analyzed the results of surgical and endovascular treatment in patients with PTIAs treated in our department and combined the results with a systematic literature review. ⋯ In this study, surgical treatment of PTIAs showed superior initial radiologic results and better long-term stability than endovascular treatment. Therefore, surgical treatment should be considered in those patients harboring PTIAs who are qualified as suitable surgical candidates after interdisciplinary consensus.

The nondominant hemisphere (usually right) is determinant for main cognitive functions such as visuospatial and social cognitions. Awake surgery using direct electrical stimulation for right cerebral tumor removal remains challenging due to the complexity of the functional anatomy and the difficulties in adapting the classical bedside tasks for awake surgery conditions. ⋯ In this second review of 2 parts, we discuss the pertinence of the neuropsychological tests available for the study of nondominant hemisphere functions for the surgery on right-sided tumors in awake surgery conditions. In conjunction with part I of the review, which focuses primarily on the anatomical, functional, and semiological basis of the right hemisphere function, this article provides a comprehensive review of current knowledge supporting the awake surgery in the right hemisphere.
