Surgical management of hemifacial spasm associated with chiari I malformation: analysis of 28 cases.
Hemifacial spasm (HFS) associated with Chiari I malformation (CIM) is rare. This study aimed to analyze the frequency of HFS associated with CIM in our department and further to investigate the clinical characteristics, treatment strategies, and outcomes of these cases. ⋯ The results suggest that MVD can still be an effective treatment for HFS when it coexists with CIM. Furthermore, posterior fossa crowdedness may be a common risk factor for the 2 diseases, and foramen magnum decompression should be considered as the primary procedure in patients with HFS and symptomatic CIM.

Previous studies firmly proved that an irregular aneurysmal shape was associated strongly with intracranial aneurysm (IA) rupture, but it is unclear how irregularly shaped IAs form. We aimed to identify the factors related to irregular shape of IAs. ⋯ Location at a bifurcation, an increased aneurysm size, and greater aspect ratio are significant independent factors associated with an irregular shape in unruptured IAs but not with smoking status, hypertension, hyperlipidemia, or diabetes mellitus.

In the context of bronchial cancers, the brain is one of the most frequent sites for metastases. Local treatments of these metastases have evolved and are often combined to obtain greater efficiency, while the main objective remains to reduce the symptoms. Radiosurgery is currently used as a primary option for patients harboring few numbers of small to middle-sized brain metastases. In nonsquamous non-small cell lung cancer (NSCLC), chemotherapy is often associated with bevacizumab. Our goal was to assess the safety of this early combination. ⋯ Radiosurgery may be safely combined with bevacizumab quite early on for patients with nonsquamous NSCLC with brain metastases.

Endovascular Treatment of Complex Distal Posterior Cerebral Artery Aneurysms with the Pipeline Embolization Device.
To assess the safety and efficacy of the Pipeline Embolization Device (PED) for endovascular treatment of complex, distal posterior cerebral artery (PCA) aneurysms. ⋯ PED use provides a practical and viable treatment option for complex, distal PCA aneurysms. Based on our limited institutional experience, PED use for treatment of complex, distal PCA aneurysms in select patients appears safe and effective.

Case Reports
Is there a place for the posterior approach in cases of acute myelopathy on thoracic disc hernia?
Acute myelopathy in cases of thoracic disc herniation (TDH) is an exceptional condition for which the treatment is not codified. Here we present the results of a standardized procedure in 10 patients who underwent surgery for acute myelopathy on TDH between December 2009 and December 2016. ⋯ Laminectomy appears to allow stabilization of the neurologic situation in rare cases of acute myelopathy on TDH. The need for complementary resection of the hernia by an anterior approach should always be discussed secondarily.
