Although there have been some reports regarding body mass index (BMI) and subtypes of stroke, there have been few concerning the relationship between BMI and location of spontaneous intracerebral hemorrhage (ICH). Determining the location of spontaneous ICH is important because outcome is thought to be affected by its location. The aim of this study was to determine whether location of spontaneous ICH varied according to BMI level. ⋯ Our findings indicate that BMI can affect the location of spontaneous ICH.

Accurate image guidance is an essential component of percutaneous procedures in the head and neck. The combination of preprocedural magnetic resonance imaging (MRI) with cone-beam computed tomography (CBCT) and real-time fluoroscopy (the "triple-overlay" technique) could be useful in image-guided targeting of lesions in the head and neck. ⋯ The combination of MRI, CBCT, and real-time fluoroscopy provides detailed anatomical information for 3D image-guided percutaneous procedures of the head and neck, especially for small lesions or lesions with features visible only by MRI.

Postoperative cerebrospinal fluid (CSF) leak in neurosurgery remains a significant source of morbidity. TissuePatchDural (TPD), a novel impermeable adhesive membrane, can be used to reinforce dural closure in cases considered at high risk to develop postoperative CSF leak. ⋯ TPD seems to be a safe tool to be used to reinforce dural closure in patients with a high risk of developing CSF leaks.

There are few reports on the effect of gamma knife surgery (GKS) for brain metastases from colorectal cancer. The purpose of this study was to identify prognostic factors for local control, complications, and survival in our series of patients treated with GKS. ⋯ GKS provides reasonable local tumor control. Local control rate is highest if the margin dose is 25 Gy and the tumor volume <5 cm(3). Radiation edema was common but rarely symptomatic. Survival is longest for young, well-functioning patients.
