An aberrant vascular channel in the petrous bone: persistent lateral capital vein?
ABSTRACT An aberrant channel was identified on CT in the petrous bone in four patients presenting with unrelated otological symptoms. These channels occurred unilaterally in each case. In two patients, the channel was seen to run between the sigmoid sinus sulcus and the superior petrosal sinus sulcus; in one of these patients, a vascular structure was identified within this channel on MRI, connecting the sigmoid sinus and the superior petrosal sinus. In the two other patients, an aberrant channel was seen between the superior petrosal sinus sulcus and the posterior genu of the facial nerve canal. There were no symptoms that could be attributed to the presence of these channels.We postulate that these aberrant vascular channels correspond to a persistent embryological vein, the lateral capital vein.

Article: Trends in head and neck radiology[Show abstract] [Hide abstract]
ABSTRACT: Trends in clinical research of head and neck radiology are well described within four articles published in the European Radiology in the last 2 years. One constant top issue is to gain more, better or new morphological information by so-called "conventional" methods (CT, MRI) with thin-sliced imaging including special reconstructions. The addition of functional or metabolic methods (e.g. diffusion-weighted MRI, dynamic contrast-enhanced MRI, positron emission tomography) to anatomical imaging is a further general trend in oncological radiology over the last few years and has been invaluable in head and neck radiology.European Radiology 03/2011; 21(3):562-4.
