An Unusual Anatomic Variation of the Jugular Foramen with Doubled Posterior Condylar Canal Una Variación Anatómica Inusual del Foramen Yugular con Canal Condilar Posterior Duplicado
A case of unusual anatomical variation of the jugular foramen (JF) with doubled posterior condylar canal (PCC) is reported. According to the presence of bridging, the JF can be defined as Type I (one septation, two compartments) on the right side and Type IV (three septations, four compartments) on the left side. The dome of the jugular fossa is present on the right, absent on the left. The jug...
متن کاملThe posterior condylar canal.
PURPOSE To assess the prevalence and appearance of the posterior condylar canal using high-resolution CT. METHODS One hundred twenty-three high-resolution temporal bone CT examinations were retrospectively reviewed for the presence or absence of the posterior condylar canal. Thirty-four gross skulls were also examined. RESULTS The posterior condylar canal was identified on CT bilaterally in...
متن کاملJugular foramen: anatomic and computed tomographic study.
The computed tomographic (CT) appearance of the jugular foramen was examined in detail, and anatomic and CT sections were correlated. The pars nervosa and pars vascularis were identified, and, with intravenous contrast enhancement, a rapid sequence of scans at a gantry angle of +30 degrees to the canthomeatal line demonstrated cranial nerves IX, X, and XI. The osseous margins of the jugular for...
متن کاملSurgical approaches to jugular foramen schwannomas: An anatomic study.
BACKGROUND The variety of surgical approaches to jugular schwannomas makes selection of an approach difficult. The purpose of this study was to define the anatomic elements of these approaches. METHODS Ten adult cadaveric heads were examined. RESULTS There are lateral, posterior, and anterior routes that access various parts of the jugular foramen. Removal of the jugular process of the occi...
متن کاملDural arteriovenous fistula involving the posterior condylar canal.
Although dural arteriovenous fistulas (DAVFs) occur in any structure that is covered by the dura mater, DAVFs at the posterior condylar canal have not been reported. We present a DAVF that involves the posterior condylar canal and drains into the posterior condylar vein and the occipital sinus, which was treated by selective transvenous embolization. Knowledge of venous anatomy of the craniocer...
