Abstract
Observing anomalies in the origin of the coronary arteries is a rare but recognised scenario during coronarography. All the major coronary arteries originating from the right sinus of Valsalva is an extremely rare anomaly, its reported incidence being 0.008% in angiographic studies. Most coronary artery variations are benign and are therefore found accidentally or postmortem. However, some anomalies in the origin of the coronary arteries are associated with myocardial ischaemia and a higher risk of sudden cardiac death. Herein, we report a sporadic case of anomalous origin of the coronary arteries, in which the right coronary artery, anterior interventricular artery and left circumflex artery arise separately from the right sinus of Valsalva, each originating from a separate ostium. Regardless of their low incidence rate, coronary artery anomalies can cause serious technical challenges during coronary angiography and percutaneous interventions because of the unusual location and course of the artery. Echocardiography, computed tomography, and magnetic resonance imaging can be useful in such cases.

Abstract
Detailed knowledge of the anatomy and different variations of the superficial branch of the radial nerve could be of great importance not only to anatomists but also to clinicians. A predominant radial nerve supply to the dorsum of the hand is rare. Herein, we present an unusual case of unilateral sensory innervation of the dorsal hand found during routine anatomical dissection of a 72-year-old at death male Caucasian cadaver. We also present a brief discussion of the reported variation and emphasize its potential clinical implications.
