Review Case ReportsLeber's optic neuropathy associated with disseminated white matter disease: a case report and review.
Leber's hereditary optic neuropathy (LHON), a mitochondrial disease, is clinically characterized by a bilateral subacute loss of central vision consecutive to optic nerve involvement. In some cases of LHON, neurological features are reported including multiple sclerosis-like (MSL) phenotype. ⋯ We discuss the respective roles of inflammation and energetic metabolism dysregulation in the development of brain lesions. We propose to treat these patients early with both antioxidative and immunosuppressive drugs in order to avoid further handicap.

Case ReportsActively bleeding intracranial aneurysm demonstrated by CT angiography.
CT angiography (CTA) is increasingly being utilized in the initial diagnosis of subarachnoid hemorrhage. While active bleeding from an intracranial aneurysm has been demonstrated on conventional angiography, CT angiogram findings of active aneurysmal hemorrhage are not well described. ⋯ A second CT scan less than 1h later confirmed the ongoing hemorrhage, with extension of hemorrhage into the subarachnoid cisterns and the ventricular system. Recognition of active aneurismal hemorrhage by CTA may modify plan of treatment and follow-up imaging.

Transsulcal approach supported by navigation-guided neurophysiological monitoring for resection of paracentral cavernomas.
The aim of the study is to evaluate tools that can improve surgical precision and minimize surgical trauma for removal of cavernomas in the paracentral area. Moreover, the surgical strategies for the treatment of symptomatic epilepsy in cavernoma patients are discussed. ⋯ The successful excision of these lesions was effected by the following four key factors: (1) the precise location of the lesion supported by intraoperative neuronavigation; (2) the preservation of the eloquent area with the aid of functional mapping; (3) a minimally invasive transsulcal microsurgical approach; and (4) the entire removal of cavernoma and hemosiderin-stained tissue.
