Clival chordoma is a rare intracranial neoplasm located in the clivus with bony extension and destruction. It is difficult to resect completely and generally has a poor prognosis. However, intradural clival chordomas have been reported with good surgical outcomes. We present a rare case of intradural chordoma and a review of the literature.

OBJECT Chiari malformation Type I (CM-I) is generally regarded as a disorder of the paraxial mesoderm. The authors report an association between CM-I and hereditary disorders of connective tissue (HDCT) that can present with lower brainstem symptoms attributable to occipitoatlantoaxial hypermobility and cranial settling. METHODS The prevalence of HDCT was determined in a prospectively accrued...

We report a case of solitary plasmacytoma of the clivus in a 55 year old male.

We report the finding of restricted diffusion in an isolated abscess of the clivus and discuss the imaging differential diagnosis, with an emphasis on the usefulness of diffusion-weighted imaging.

A 38-year-old man with pneumococcal meningitis, pneumocephalus, and CSF rhinorrhea was admitted to our hospital. The CSF rhinorrhea had no traumatic or iatrogenic etiology. The patient was treated with meropenem and recovered from meningitis. Axial plain CT showed pneumocephalus (figure 1, A and B), but no skull defects. Three-dimensional CT revealed defects of the posterior walls of the spheno...

The transoral approach is a direct route to the clivus. However, application of this approach is infrequent because of the risk of cerebrospinal fluid (CSF) fistula and subsequent meningitis. We report a case of clival metastatic tumor treated by staged operation without CSF leakage. A 39-year-old man was found to have a tumor in clivus extending to the intradural space. Two-staged resection th...

the clivus is the surface of a portion of the occipital and sphenoid bones in the base of the skull. (1)it is surrounded by the neurovascular structures of the brainstem, as well as internal carotid arteries. tumors of the clivus can be benign (chordoma)or malignant (chondrosarcoma).(2) chordomas are rare, aggressive, slow-growing, invasive, and locally destructive tumors that arise from the no...

abstractwe are reporting a 43-year-old female breast cancer case with a solitary metastatic adenocarcinoma in clivus. this patient with a stage ii (t1n1m0) breast cancer history has been followed for 7 years.  modified radical mastectomy (mrm) and 6 courses chemotherapy with cmf (cyclophosphamide, metotrexate, 5fu) regimen were done for her at the time of diagnosis. also, she took tamoxifen twe...

Methods Cross-sectional analysis of craniometric parameters from individuals submitted to magnetic resonance at an outpatient imaging center between 2011 and 2012. Results Of 181 analyzed cases, the Welcker basal angle averaged 128.96º (SD 6.51), median distance between apex of the odontoid and Chamberlain's line was 2.27 mm (IQR -1.23-4.47) and the median clivus-canal angle was 150.5º (IQR 1...
