The Vertebral Artery Convergence to the Cervical Spine in Elders.

Background: In the older population, tortuosity of the vertebral artery (VA), uncovertebral joint (UVJ) osteoarthritis, and abnormal vertebral alignment may alter the normal anatomy.

Aim: We aimed to determine the anatomical variations and relationships between the cervical segment of the VA and the cervical spine with regard to ageing.

Materials And Methods: In this retrospective cross-sectional study, the computed tomography angiography scans of 110 subjects were reviewed.

Unilateral cervical and petrosal segment agenesis of the internal carotid artery with rete mirabile.

The carotid rete mirabile (RM) is a physiological network between the internal and external carotid arterial systems. In this paper, an extremely rare case is presented, in which internal-external carotid artery anastomoses and a dilated ascending pharyngeal artery, due to unilateral agenesis of the cervical and petrous segments of the internal carotid artery (ICA), is presented.

Diffusion-weighted magnetic resonance imaging in the assessment of choroid plexus aging.

Recent studies have pointed out dysfunction and histopathological changes of the choroid plexuses (CPs) with aging. This paper reviews apparent diffusion coefficient (ADC) values of the CPs for age-related changes. All the brain MR images of the patients between January 2013 and June 2014 in our Radiology Department were retrospectively investigated.

Right Liver Lobe Hypoplasia and Related Abnormalities.

Background: Hypoplasia and agenesis of the liver lobe is a rare abnormality. It is associated with biliary system abnormalities, high location of the right kidney, and right colon interposition. These patients are prone to gallstones, portal hypertension and possible surgical complications because of anatomical disturbance.
