Morphometric and radiomorphometric study of the correlation between the foramen magnum region and the anterior and posterolateral approaches to ventral intradural lesions

AIM: To identify the range of dimensional morphometric variability correlated to the basilar and condylar part of the occipital bone, which may affect the choice of approach to ventral intradural foramen magnum (FM) lesions. MATERIAL and METHODS: In total, 25 dry skulls and 50 head computed tomography (CT) scan results have been assessed in detail, focusing on the FM, occipital condyles, jugular tubercles (JT), and hypoglossal canals (HC). A morphometric analysis has been carried out using li...

Intraoperative ultrasound and 5-ALA: the two faces of the same medal?

BACKGROUND: High grade gliomas (HGG) still remain the most demanding neuro-oncological challenge. Several studies have confirmed that the extent of resection (EOR) correlates with increased survival in patients with HGGs. The gross total resection of HGGs can be difficult and challenging. For this reason, technologies to improve EORhave been of interest. The aim of this paper was to analyze advantages and limitations of both intraoperative fluorescence and intraoperative ultrasound (IOUS) res...

Intraneural Ewing Sarcoma of Fibular Nerve: Case Report, Radiologic Findings and Review of Literature

Background: Intraneural Ewing sarcoma (ES) was first described in 1918 by Stout in a tumor of the ulnar nerve. These tumors are in the category of ES family of tumors, together with ES of bone, extraosseous ES, and primitive neuroectodermal tumor. ES typically occurs in the second decade of life; only 20% of cases affect elder people. The most frequently involved sites are the craniospinal vault and cauda equina, while the peripheral nerve location is extremely rare (only 11 cases mentioned i...
