Review Case Reports
Delayed traumatic aortic pseudoaneurysm formation causing vertebral body erosion and back pain: case report and literature review.
Aortic pseudoaneurysms are a rare cause of chronic back pain, usually resulting from compression of the adjacent neurovasculature. It is uncommon for patients with pseudoaneurysms of the abdominal aorta to present in a delayed fashion after initial traumatic injury. ⋯ In our patient, a combined surgical and endovascular (hybrid) approach led to the complete resolution of his back pain symptoms and to complete exclusion of the pseudoaneurysm on follow-up imaging. Endovascular management of aortic pseudoaneurysms may be a reasonable alternative to open surgery in high-risk patients; however, this approach may result in a higher recurrence of pseudoaneurysm and initial presenting symptoms. Further investigation is needed to elucidate the efficacy of endovascular treatment of these lesions.

Multicenter Study
How early can we perform cranioplasty for traumatic brain injury after decompressive craniectomy? A retrospective multi-center study.
Decompressive craniectomy (DC) is used to treat intractable intracranial hypertension after severe traumatic brain injury (TBI). Cranioplasty (CP) is typically performed weeks or months later. However, the optimal timing for CP is unknown. We aimed to determine the earliest possible time point for CP. ⋯ CP can be performed at around 34 days after DC for TBI. Ventriculomegaly occurred less frequently and the 6-month Glasgow Outcome Scale score was better in the early CP group than in the late CP group.

Total removal of craniopharyngiomas is burdened by high morbidity. In cases of a cystic or mixed craniopharyngioma, when the symptoms are caused by the cystic component of the tumor, a less invasive surgical approach aiming at cyst drainage may be recommended. Here, we report our experience with intraventricular neuroendoscopy, describe our clear-cut surgical technique, and analyze results in the context of literature data. ⋯ We describe a neuroendoscopic treatment of cystic craniopharyngiomas that, without adjuvant radiotherapy, is safe and effective and ensures long-term recurrence-free survival.

Multicenter Study Comparative Study
Is there an indication of intraoperative MRI in subtotal resection of glioblastoma? - A multicenter retrospective comparative analysis.
Surgery in patients with highly eloquent glioblastoma (GB) remains challenging. The aim of this study was to evaluate influence of use of intraoperative magnetic resonance imaging (iMRI) on extent of resection (EOR), clinical outcome, and survival in patients with preoperatively intended subtotal resection of GB. ⋯ Maximum safe resection is an important prognostic factor for patients with eloquent GBs. iMRI seems to be a relevant tool to achieve this goal.

Review Case Reports
Schwannomas of the Frontal Sinus: Cases and Review of the Literature.
Although schwannomas are commonly found in the head and neck region, sinonasal tract involvement is extremely rare, estimated as <4%. The presence of these lesions in the frontal sinus is even less common. ⋯ Although these lesions have traditionally been approached through larger craniotomies and open procedures, we describe less invasive approaches for these rare frontal sinus schwannomas and demonstrate them as a valid alternative with minimal morbidity for patients.
