A 37-year-old man with no medical history, apart from a lifelong horizontal diplopia, underwent brain magnetic resonance imaging, which revealed a curvilinear posterior pericallosal lipoma and a pineal cyst. Corpus callosum lipomas, with an incidence of 0.1%-0.5%, do not require neurosurgical treatment, except in rare cases of malformations causing epilepsy. ⋯ In this case, ophthalmologic examination and magnetic resonance imaging were not consistent for a tectal plate compression and the findings were considered incidental. The association of these 2 abnormalities, which has not been described before, might reflect an interrelated embryologic development for pineal gland and midline lipomas, which derive from aberrant mesenchymal primitive meninx.

Large or giant thrombosed intracranial aneurysms (LGTIAs) are highly associated with poor prognosis and remain a challenging disease to treat by either surgery or endovascular treatment (EVT). EVT is considered more difficult for complicated aneurysm like LGTIAs. To understand long-term clinical and angiographic outcomes of EVT for LGTIAs, we retrospectively analyzed our single-center data on multimodality EVT for patients with LGTIAs. ⋯ Multimodality EVT for LGTIAs was performed with similar clinical outcomes and better radiologic outcomes compared with previous reports. New innovative techniques and devices are expected to be helpful for long-term aneurysm occlusion.

Case Reports
A case of spontaneous regression of radiologically diagnosed epidermoid cyst originated from cerebellopontine angle.
Generally, asymptomatic epidermoid cysts (ECs) or ECs with minor symptoms controlled by medication are not treated further. Although epidermoid carcinomas are only sporadically reported, the possibility of malignant transformation of ECs is of concern. ⋯ The reduction of an EC is extremely rare. We report a case of spontaneous regression of an EC and consider similar previous cases.

We report the first case of cervical spine chondrosarcoma in a Wilms tumor survivor. ⋯ Through our experience with this case, we would like to suggest a possible unknown genetic syndrome predisposing patients with Wilms tumor to chondrosarcoma as secondary neoplasms. We would also like to re-emphasize the need for vigilance when assessing patients with a history of Wilms tumor.

Observational Study
Risk Factors Associated with Symptomatic Deep Vein Thrombosis Following Elective Spine Surgery: A Case-Control Study.
Few studies provide insight into risk factors (RFs) associated with postoperative deep vein thrombosis (DVT) following elective spinal surgery. DVTs are detrimental in this population because of the risk of pulmonary embolization or surgical site hemorrhage with treatment. ⋯ These results suggest that patients with a history of DVT undergoing elective spinal surgery are at higher risk of developing symptomatic DVT postoperatively resulting in significantly increased length of stay. Further studies on additional preoperative screening and medical optimization in elective spine surgery patients may help reduce the rate of symptomatic, postoperative DVT.
