A simple necropsy technique for the removal of the craniocervical junction was devised: a relatively small specimen comprising part of the clivus, the foramen magnum, and cervical vertebral canal is removed in one piece with the medulla and spinal cord inside, and examined systematically after fixation. This method, used in a series of patients with chronic craniocervical instability, allows bo...

Cases of cerebrospinal fluid (CSF) rhinorrhea due to clival fracture are rare. We present a case of bacterial meningitis with CSF rhinorrhea after a clival fracture. Heavily T2-weighted images showed a bone flap in the thinned clivus and fluid collection in the sphenoid sinus. CSF rhinorrhea developed at 1 month after mild trauma. The fracture may have been caused by the trauma and/or by the pr...

We examined 50 computed tomographic (CT) scans that included sections through the base of the skull at a wide variety of angles. Each of these examinations had an accompanying localizing radiograph so that the angle at which the scan had been obtained could be ascertained . The scans were randomly arranged and rated as to how well 11 structures in the skull base were visualized: (1) foramen mag...

A 44-year-old man without any remarkable medical history developed double vision and numbness of the left face. At his first visit, the patient presented the neurological manifestations of Garcin’s syndrome, involving the left third to twelfth cranial nerves. Brain magnetic resonance imaging revealed a tumor of mainly the left sphenoid sinus and clivus, and the tumor showed iso-intensity on T1-...

Chordomas are dysembryogenic tumors originating from the notochordal process [1] [2]. They are aggressive tumours with unique diagnostic and management challenges. Primary therapy is complete surgical removal of the tumour as much as possible. The likelihood of recurrence is high in spite of complete surgical resection. A 52-year-old female patient presented with complaints of decreased vision ...

Bone scintigraphy is an extremely valuable technique in diagnosis and treatment planning for patients with condylar hyperplasia (CH). The main objective of this study was to develop approach determine normal activity values the mandibular condyles, adjusted age sex, through quantitative analysis bone single-photon emission computed tomography (SPECT) on a condyle-by-condyle basis compare these ...

Intracranial chordomas are typically clival and extradural in location, yet these tumors can obviously invade the dura. However, primary intradural chordomas without local extension is a rare event with approximately 47 cases reported in literature. Furthermore, all intradural chordoma reports appear to be extraventricular in location.[1,2] In addition, through advances in technology and optics...
