The peculiar radiological and pathological findings of four pediatric cases admitted to the University Hospital of Padua between 1990 and 2007 are described. In all cases, the contrast-enhanced head and spine magnetic resonance images revealed thickened and abnormally enhancing subarachnoid spaces particularly at the level of basal cisterns and(More)
Chordoid meningioma is a rare meningothelial tumor characterized by chordoma-like histological features with lymphoplasmacellular infiltration. This tumor is often seen in children, but not in adults, with a systemic inflammatory syndrome (iron-resistant microcytic anemia and/or dysgammaglobulinemia) and very rarely with a persistent moderate hyperthermia.(More)
Idiopathic spinal cord herniation (ISCH) is a rare, although increasingly recognized, cause of myelopathy. It is the result of an anterior dural defect in the thoracic spine through which the spinal cord herniates. Surgical restoration of the herniated cord to its normal position is usually followed by significant improvement in patients' clinical status.(More)
Cervical degenerative pathology produces pain and disability, and if conservative treatment fails, surgery is indicated. The aim of this study was to determined whether anterior decompression and interbody fusion according to Cloward is effective for treating segmental cervical degenerative pathology and whether the results are durable after a(More)
The aim of this study is to determine if radical microsurgical removal of cervical intramedullary spinal cord tumors (CIMSCT) is achievable without causing respiratory, motor and sphincter deficits. Sixteen consecutive patients, who underwent surgical removal of a cervical intramedullary spinal cord tumor between 1988 and 1997, are presented. Surgical(More)
OBJECTIVE The usefulness of intraoperative microvascular Doppler (IMD) in preventing an incorrect placement of the clip during intracranial aneurysm surgery is described. Such incorrect placement of the clip may cause new bleeding or ischemic accident as a consequence of incomplete exclusion of the aneurysm or stenosis/occlusion of the parent and/or(More)
Spinal cord back shift has been considered the desired end point of posterior decompression procedures for cervical spondylotic myelopathy (CSM). However, the association with postoperative outcomes has not been definitively demonstrated. The aim of this review is to obtain an overview of the current knowledge on the spinal back shift after posterior(More)
Aggressive pituitary adenomas (PAs) are clinically challenging for endocrinologists and neurosurgeons due to their locally invasive nature and resistance to standard treatment (surgery, medical or radiotherapy). Two pituitary-directed drugs have recently been proposed: temozolomide (TMZ) for aggressive PA, and pasireotide for ACTH-secreting PA. We describe(More)
To characterize in vivo the transpedicular approach (TA) as an alternative route to study intervertebral disc (IVD) regeneration strategies in a sheep model. 48 IVD of 12 sheep were used. TA was performed under fluoroscopy, followed by nucleotomy (2-mm shaver resector). A polyurethane scaffold was used to repair the end-plate. X-ray and MRI images were(More)
