Comparative StudyVolumetric response to radiosurgery for brain metastasis varies by cell of origin.
The aim of this study was to evaluate the imaging response of brain metastases after radiosurgery and to correlate the response with tumor type and patient survival. ⋯ The various types of imaging responses of metastatic brain tumors after stereotactic radiosurgery depend in part on tumor type. However, the type of response only correlates with survival in patients with breast cancer.

Morphological predictors of intraprocedural rupture during coil embolization of ruptured cerebral aneurysms: do small basal outpouchings carry higher risk?
This study aimed to investigate morphological predictors of intraprocedural rupture (IPR) during coil embolization of ruptured cerebral aneurysms. ⋯ Based on the authors' data, the more general groups of multilobulation and daughter sac were not significantly associated with IPR, although the more specific subgroup with an SBO was. More confirmation studies on these results are required, but they point to the possibility that SBO (with its possible connection to basal rupture) is an important morphological risk factor for IPR during coiling. In addition, future comparison of coiling and clipping treatment for ruptured aneurysms associated with an SBO seems necessary.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare soft-tissue neoplasm with metastatic potential and needs to be recognized as such, because it can be mistaken for other types of sarcoma due to its unremarkable appearance. This 49-year-old man presented with an approximately 5-cm mass on the anteromedial aspect of his left thigh that slowly increased over 10 years. Clinical symptoms were limited to local discomfort and intermittent distal numbness. ⋯ He has since been healthy and disease free for a total of 4 years in follow-up. This case documents, to the authors' knowledge, the first observation of an LGFMS associated with a peripheral nerve. It also supports the use of fluorescence in situ hybridization analysis as an essential diagnostic method in establishing the diagnosis of LGFMS.
