We explore a case of Benign Paroxysmal Positional Vertigo in the context of Persistent Hypoglossal Artery (PHA) and bilateral Madelung Deformity (MD). PHA is associated with a raft of major adverse cardiovascular events. MD can result from manifold conditions such as Turner's Syndrome and mesomelic dwarfism. In this case, the patient's positive family history of MD across generations is suggestive of inherited mutation in the Short Stature Homeobox (SHOX) Gene. We discuss the putative impact of SHOX on the genesis of Benign Paroxysmal Positional Vertigo (BPPV) in a patient with PHA and bilateral MD.
