Replaced posterior cerebral artery (PCA): origin of all branches of the PCA from the anterior choroidal artery diagnosed by MR angiography.

Surg Radiol Anat 2019 Apr 3. Epub 2019 Apr 3.

Department of Cerebrovascular Surgery, Saitama Medical University International Medical Center, Saitama, Japan.

We present a rare variant of the right posterior cerebral artery (PCA), recently named "replaced PCA," that demonstrates the origin of all its branches from the right anterior choroidal artery (AChA) on magnetic resonance (MR) angiography. In this variation, the right posterior communicating artery (PCoA) is hypoplastic and resembles the transposition of the AChA and PCoA. Detection of such rare arterial variations on MR angiographic images requires careful review of images, including source images, and partial maximum-intensity-projection images aid their identification.

Anomalous anastomosis between the external carotid artery and vertebrobasilar artery via the hypoglossal canal: a case report and review of literature.

Surg Radiol Anat 2019 Feb 7. Epub 2019 Feb 7.

Department of Neurology, Yokohama Brain and Spine Center, 1-2-1 Takigashira, Isogo-ku, Yokohama, 235-0012, Japan.

We report a case of an anomalous anastomosis formed between the external carotid artery (ECA) and the vertebrobasilar artery (VBA) and passing through the hypoglossal canal. A carotid-vertebrobasilar anastomosis of this kind is typically considered a variant of persistent primitive hypoglossal artery which usually originates from the internal carotid artery. However, the anastomotic vessel in this case had a common trunk with the occipital artery (OA), a remnant of the primitive proatlantal artery. Read More

The adaption of the bony microstructure of the human glenoid cavity as a result of long-term biomechanical loading.

Surg Radiol Anat 2019 Apr 1;41(4):401-408. Epub 2019 Feb 1.

Department of Biomedicine, Musculoskeletal Research, University of Basel, Pestalozzistrasse 20, 4056, Basel, Switzerland.

Structural arrangements of the bony microstructure of a joint through adaptational processes are thought to be determined by the biomechanical demands and its changes. Pursuing this theory of "form follows the biomechanical function", the load distribution of the glenoid cavity, as it is mirrored in its mineralization pattern, should link not only to its thickness distribution, but also will have an impact onto the trabecular network below. To prove and confirm this hypothesis, we analysed the mineral distribution in correlation to the subchondral bone plates thickness and the distribution of architectural parameters of the trabecular network below.
