Diverticulum Of Kommerell

Diverticulum of Kommerell is a congenital anomaly in the development of the primitive embryonic aortic vasculature resulting in either an aberrant left subclavian artery (ALSA) from a right-sided aortic arch (RSAA) or an aberrant right subclavian artery (ARSA) from a left-sided aortic arch (LSAA). Kommerell’s diverticulum (KD), is extremely rare in the general population having prevalence of 0.7–2.0 %. KD with true aneurysmal dilatation like any vascular lesion of the thoracic aorta weakens the vasculature and increases the risk of aortic rupture. Timely surgical intervention is of paramount importance in most of these cases. Variable clinical presentations in patients with KD are either a result of compression of some mediastinal organs or strangulation by the vascular ring from the aberrant subclavian artery (ASA). We report a case of a 39 years old Chinese female with a rare co-existence of a huge KD with a microaneurysm, an aberrant right subclavian artery (ARSA), and ventricular septal defect (VSD). She underwent a successful operation and all her pre-surgical symptoms disappeared.

A 69-year-old man who had been bedridden in nursing home because of a 5-year history of progressive supranuclear palsy (PSP) was admitted due to aspiration pneumonia. Besides neck dystonia in extension, he showed “alternating flexed–extended posturing”, in which the arm was flexed on one side and extended on the other. Magnetic resonance imaging of the brain revealed global cerebral atrophy that predominantly affected the cortex and midbrain. The mechanisms of complex posturing in late-stage PSP may sometimes be related to decortication and decerebration as well as dystonia, and “alternating flexed–extended posturing” might be one of the phenotypes of pathological progression in PSP.
