Abstract:
We present an unusual case of chordoma arising entirely from the lateral skull base with imaging features suggestive of a paraganglioma. Clinical history, management, histopathology, and imaging characteristics are described, including a review of gallium-dotate PET scanning somatostatinreceptor-positive tumors. We further provide a review of management options, including a summary of our approach with surgical biopsy via retrosigmoid and resection via transtemporal approaches. Based on radiologic characteristics and location, lateral skull base chordoma may arise with isolated lateral skull base involvement and has the potential to be misidentified as a glomus jugulare on initial workup.

01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

On the other hand, the vertebral veins, unlike their arterial counterparts, are not primarily responsible for brain drainage. Instead, they drain the cervical vertebrae, spinal cord, and some small...
