Presurgical role of MRI tractography in a case of extensive cervicothoracic spinal ependymoma
2017
Background: Intramedullary spinal ependymoma is a tumor, hardly characterizable with conventional magnetic resonance (MR) imaging only. MR diffusion tensor imaging (DTI) with three dimensional fiber tracking reconstructions allows the evaluation of the relationship between neoplasm and white matter fiber tracts, being a powerful tool in presurgical planning. We present DTI findings in a case of a young female with an extensive cervicothoracic spinal ependymoma. Case Description: The patient complained of a 2 month history of acute urinary retention, weakness and numbness on the lower limbs and the upper left limb. She underwent MR imaging that showed an extensive cervicothoracic spinal mass…
Role of Hemodynamic Forces in Unruptured Intracranial Aneurysms: An Overview of a Complex Scenario.
2017
Background An understanding of the natural history of unruptured intracranial aneurysms (IAs) has always played a critical role in presurgical or endovascular planning, to avoid possibly fatal events. Size, shape, morphology, and location are known risk factors for rupture of an aneurysm, but morphologic parameters alone may not be sufficient to perform proper rupture risk stratification. Methods We performed a systematic PubMed search and focused on hemodynamics forces that may influence aneurysmal initiation, growth, and rupture. Results We included 223 studies describing several hemodynamic parameters related to aneurysm natural history. In these studies, different modalities of aneurysm…
Intracranial venous sinus thrombosis as unusual presentation of Bing-Neel syndrome: case illustration.
2017
A 42-year-old woman presented with progressive blurred vision, vertigo, and headache. MRI showed bilateral intraocular protrusion of the optic nerve head and right transverse sinus thrombosis . Low-molecular-weight heparin was administered without symptom relief. Additional MRI showed left frontoparietal arachnoid space obliteration by pathological tissue, and infiltration of the sagittal and right transverse sinuses. After Gd administration, we observed diffuse enhancement of the dura in the left cerebral hemisphere and subdural and epicranial soft-tissue infiltration . A biopsy of the extra-axial tissue was performed. Histological examination showed a neoplasm composed of large cells with…
