Atypical teratoid/rhabdoid tumor is a highly malignant tumor of the central nervous system, usually occurring in the posterior fossa in infants and young children. Supratentorial example is relatively rare, especially with involvement of the cerebral ventricle system. Herein, we reported 2 cases of atypical teratoid/rhabdoid tumor located in the septum(More)
BACKGROUND Although diffusion tensor imaging has been used to monitor Wallerian degeneration, the exact relationship between the evolution of diffusion indices and its underlying pathology, especially in central nervous system, remains largely unknown. Here we aimed to address this question using a cat Wallerian degeneration model of corticospinal tract. (More)
Isolated cortical vein thrombosis often produces a focal lesion. Because of the rapid development of collateral circulation, increased intracranial pressure has never been reported in a patient with isolated cortical vein thrombosis. The diagnosis of isolated cortical vein thrombosis is based mainly on MRI, catheter digital subtraction angiography, and(More)
The therapy of focal epilepsy remains unsatisfactory for as many as 25% of patients. The photolysis of caged-γ-aminobutyric acid (caged-GABA) represents a novel and alternative option for the treatment of intractable epilepsy. Our previous experimental results have demonstrated that the use of blue light produced by light-emitting diode to uncage(More)
PURPOSE To investigate the feasibility of T2W-SPACE technique in early detection of WD, the signal evolutions of degenerated corticospinal tract (CST) on T2W-SPACE, and their underlying pathological changes. MATERIALS AND METHODS The WD model of the CST was established in 23 cats through excision of cortical origins of the tract. Eight cats were scanned(More)
OBJECTIVE To study the expression of autophagy-related proteins (Beclin-1, LC3 and p62) in brain tissue with malformations of cortical development and related molecular pathogenesis. METHODS The brain tissue of 18 cases with epileptogenic foci resection, including 6 cases of tuberous sclerosis complex (TSC), 6 cases of focal cortical dysplasia type IIb(More)
OBJECTIVE To explore the clinicopathological features and imaging characteristics of non-Langerhans cell histiocytosis in central nerve system, thus to facilitate the diagnosis and differential diagnosis. METHODS A total of ten cases were enrolled in the study, with seven cases of Rosai-Dorfman disease (RDD) and three cases of xanthoma disseminatum (XD).(More)
