Condylar jugular diverticulum.
We would like to present 6 instances of an internal jugular bulb diverticulum extending into the occipital condyle, which, to the best of our knowledge, has not been described in the English-language literature.This asymptomatic variant was detected incidentally on 6 patients. Computed tomography was performed on all 6 cases, and magnetic resonance imaging and magnetic resonance venography was performed in 2 cases. The condylar jugular diverticula presented as a well-defined defect in the occipital condyle contiguous with the jugular bulb on computed tomography. Magnetic resonance venography showed flow within the diverticulum. There was no definite relationship to a dominant transverse sinus. Recognition of this variant will help to avoid potential confusion with pathological lesions in the occipital condyle, especially on magnetic resonance imaging.
