Review Case Reports Meta Analysis
Blister-like Aneurysms in Atypical Locations: A Single-Center Experience and Comprehensive Literature Review.
Blister-like aneurysms (BLAs) were originally described to arise typically along the nonbranching segment of the dorsal wall of the internal carotid artery (ICA); however, BLAs located in areas other than the dorsal ICA have been described more recently. We present a case series of "atypical" BLAs and a systematic review of the literature on this subject. ⋯ Endovascular treatment of BLAs seems to be associated with reduced morbidity and mortality and to provide a better outcome compared with surgical approaches. Further prospective studies are needed to confirm these results. It is important for clinicians to remember that BLAs may also occur in sites other than the typical ICA location.

Affective symptoms are frequent in patients with brain tumors. The origin of such symptoms is unknown; either focal brain injury or reactive emotional distress may be responsible. This cross-sectional pilot study linked depressive symptoms and anxiety to white matter integrity. The objective was to test the hypothesis of a relationship between tissue damage and brain function in patients with brain tumors and to provide a basis for further studies in this field. ⋯ Our results suggest that neurobiologic mechanisms related to the integrity of tissue in specific white matter tracts may influence affective symptoms in patients with brain tumors, and these mechanisms can be investigated with diffusion tensor imaging. However, prospective observational studies are needed to investigate further the links between brain structures and the severity of affective symptoms in this patient population.

Glioblastoma (GBM) occurs more commonly in elderly patients. However, these patients are often excluded from clinical trials. The absence of solid evidence has resulted in a nihilistic view of GBM in the elderly and a traditionally conservative treatment approach. In particular, the safety of surgical resection for both primary and recurrent GBM is poorly understood in elderly patients. ⋯ We conclude that in select patients, age alone should not preclude the decision to pursue aggressive surgical management.

Case Reports
Synchronous Aneurysmal Subarachnoid Haemorrhage And Medulloblastoma In A 6 Year Old Girl.
Hemorrhage in medulloblastoma (MB) is a rare clinical entity with the undeniable potential for catastrophic repercussions. This case report highlights the first incidence of intraoperative subarachnoid hemorrhage (SAH) in a patient with MB secondary to an intracranial aneurysm. ⋯ Intraoperative hemorrhage in MB is a very rare occurrence. We describe the first case of hemorrhage in MB secondary to an intracranial aneurysm. MB has a predisposition to bleed spontaneously that can have catastrophic repercussions. Sudden clinical deterioration after insertion of external ventricular drainage should be susceptive of intracerebral hemorrhage. In cases of uncertain etiology, investigation of SAH with cerebral angiography is recommended.
