HHV 6 –7 reactivation causing Pityriasis Rosea and labyrinthitis

Pityriasis Rosea (PR) and labyrinthitis are most commonly caused by viral infections. PR presents with a characteristic rash while labyrinthitis presents with vertigo, tinnitus and hearing loss. However, the coexistence of PR and Labyrinthitis remains an uncommon event. Human Herpes Virus (HHV) 6 and 7, are common infections in childhood, and their reactivation causes Pityriasis Rosea. But these viruses are not known to have any involvement with the inner ear or the 8th cranial nerve (CN).
