Vidal,Claudio Henrique Fernandes; Ferreira,Maria Lucia Brito; Azevedo Filho,Hildo Rocha Cirne de; Gurgel,Fernando Viana; Brainer-Lima,Alessandra MertensThe diagnosis of schistosomal myelitis (SM) is frequently presumptive because no findings from any complementary examination are pathognomonic for this disease. The present report describes some abnormalities seen on magnetic resonance imaging (MRI) evaluation of a series of SM patients and discusses their etiopathogenesis. Methods: This study evaluated SM patients at the time of their diagnosis. These patients...
Ganglioglioma: comparison with other low-grade brain tumors
Brainer-Lima,Paulo Thadeu; Brainer-Lima,Alessandra Mertens; Azevedo-Filho,Hildo RochaMETHOD: Forty-two patients with low-grade brain tumor and refractory epilepsy were studied. The mean age was 22.3 years. They were divided into two groups: Group A, patients with ganglioglioma (n=19) and group B, patients with other low-grade tumors (n=23) (14 astrocytoma, 6 oligodendroglioma, 2 dysembryoplastic neuroepithelial tumor, and 1 xanthoastrocytoma). RESULTS: Age at seizures onset was 7 years or less...
