OBJECTIVE In recent years, endoscope started to be used for the excision of the brainstem lesions or those localized in the anterior part of the brainstem. In this paper a case of clival meningioma resected through endoscopic endonasal transclival route has been presented with illustrations, live surgery videos demonstrating the surgery step by step. CASE REPORT A 35-year-old male patient con...

OBJECTIVES/HYPOTHESIS Nonchordomatous lesions of the clivus are rare entities. Nasopharyngeal radium irradiation (NRI) treatment consists of application of radium to the posterior nasopharynx near the orifice of the Eustachian tubes, an area adjacent to the clivus. Here we present a unique case of a patient with a history of NRI 70 years prior to presentation with a space-occupying clival lesio...

introduction spinal tumours may be classified in three groups: 1) extradural, 2) intradural extramedullary and 3) intramedullary spinal cord tumours. intradural extramedullary tumours arise from the leptomeninges or nerve roots and include schwannomas. a schwannoma is usually a firm grey-whitish tumour growing near a nerve trunk or ramus. it can be separated from the nerve without damaging neur...

Background: Over-expression of CD117 and cytokeratin 20 (CK20) is seen in many malignancies. Given that few studies have been conducted regarding the role of these biomarkers in the etiology of bladder tumours, this study aimed to evaluate the prognostic value of CD117 and CK 20 biomarkers in the benign and malignant tumours of urinary bladder carcinoma. Methods: This case-control study was co...

IMPORTANCE Nonchordomatous clival lesions are rare and represent a wide range of different benign and malignant pathologies. For an accurate and specific final diagnosis, biopsy procedures and/or resections followed by histologic examination are mandatory. OBJECTIVE To illustrate the challenges in obtaining a final histologic diagnosis in patients with various types of clival lesions. DESIG...

BACKGROUND The clivus is a bone region between dorsum cella and foramen magnum. It can be evaluated very clearly in routine brain magnetic resonance imaging (MRI) dueto its central location. OBJECTIVES Quantitative and qualitative evaluation of the clivus and its changes according to age in a group of healthy people. PATIENTS AND METHODS The transition of clival bone marrow to fatty marrow ...

An 89-year-old male presented with cerebrospinal fluid (CSF) rhinorrhea associated with head trauma sustained as a pedestrian in a traffic accident. Computed tomography (CT) showed pneumocephalus and multiple cranial bone fractures, including the clivus. Although the CSF rhinorrhea was treated conservatively for a week, clinical symptoms did not improve and surgical repair was performed. Preope...

UNLABELLED INTRODUCTION Clival chordomas present with headache, commonly VI cranial nerve palsy or sometimes with lower cranial nerve involvement. Very rarely, they present with cerebrospinal fluid rhinorrhoea due to an underlying chordoma-induced skull base erosion. CASE PRESENTATION A 60-year old Caucasian woman presented with meningitis secondary to cerebrospinal fluid rhinorrhoea. At f...
