BACKGROUND: Extraskeletal mesenchymal chondrosarcoma (ESMCS) is an unusual pathologic variant of chondrosarcoma. There are no specific clinicoradiographic parameters to distinguish it from other intracranial pathologies. The diagnosis can be established only on the basis of histopathology, which may pose significant challenges in certain unusual locations. PURPOSE: In this case, we discuss the pitfalls in diagnosis, management, and major characteristics of ESMCS with a review of current literature...

INTRODUCTION: Tumors affecting structures in the vicinity of jugular foramen such as glomus jugulare require microsurgical approach to access this region. These tumors tend to alter the normal architecture of the jugular foramen by invading it. Therefore, it is not feasible to have correct anatomic visualization of the foramen in the presence of such pathologies. Hence, a comprehensive knowledge of the jugular foramen is needed by all the neurosurgeons while doing surgery in this region...

Hypoglossal canal meningiomas (HCMs) are extremely rare, and a consensus has yet to be reached regarding the most appropriate treatment approach for these types of tumors. Surgical procedures to the hypoglossal canal are often complex and lengthy, and are often associated with high rates of morbidity. Several approaches have been used to remove such lesions. Most of these approaches have been adapted from methods used for jugular foramen surgery. Our goal is to present an approach that improves visualization of the hypoglossal canal, thus reducing this pathology's risk of morbidity...

Papillary meningioma (PM) is a rare histological variant of intracranial meningioma, which displays an aggressive behavior and its management is difficult. The present study reported the case of a 21-year-old male patient, who presented with headaches and dizziness. Upon neurological examination, left hypoglossal nerve palsy and left cerebellar signs were observed. Computed tomography and magnetic resonance imaging scans of the brain revealed a high-density mass in the left jugular foramen area. Following an uneventful complete surgical resection of the tumor, a definitive diagnosis of Grade III PM was determined based on the histopathological findings, according to the World Health Organization classification...
