We describe a case in which an incidental left carotid aneurysm was found during the preoperative evaluation of a pituitary adenoma. After magnetic resonance imaging (MRI) and angiography delineated their characteristics, we chose to treat both lesions simultaneously through a left supraorbital keyhole approach. The aneurysm clipping was followed by intracapsular resection of the tumor that was identified later as a non-secretory adenoma. The postoperative course was uneventful. This case shows that in carefully selected patients it is possible to treat successfully concurrent conditions through a minimally invasive approach, with the well known advantages of low morbidity and a short hospital stay.
We report a partially retrospective and longitudinal study of patients with optic neuritis (ON) that developed multiple sclerosis (MS). We assessed clinical features or factors that might differentiate these patients from those with ON that did not develop MS. Of the cases followed, 110 (67%) were found to have an idiopathic origin of the disease; whereas 55 (33%) were found to develop it secondary to another disease. Of the 110 idiopathic cases, 13 (12%), developed MS over an average of 2 years. The results of these patients in the laboratory analyses of blood and CSF as well as the results of the MRI and evoked potential studies, were significantly different from the ON patients without MS. We conclude that the percentage of patients with ON in our sample that developed MS is similar to that found in Japan and is relatively low in comparison to other reports.
Anterior exposure for cervical chordomas remains challenging because of the anatomical complexities and the restoration of the dimensional balance of the atlanto-axial region. In this report, we describe and analyze the transmandibular transoral approach and multilevel spinal reconstruction for upper cervical chordomas. We report two cases of cervical chordomas (C2 and C2-C4) that were treated by marginal en bloc resection with a transmandibular approach and anterior-posterior multilevel spinal reconstruction/fixation. Both patients showed clinical improvement. Postoperative imaging was negative for any residual tumor and revealed adequate reconstruction and stabilization. Marginal resection requires more extensive exposure to allow the surgeon access to the entire pathology, as an inadequate tumor margin is the main factor that negatively affects the prognosis. Anterior and posterior reconstruction provides a rigid reconstruction that protects the medulla and decreases axial pain by properly stabilizing the cervical spine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
