Table 1 Differential diagnosis of Ramsay hunt syndrome

From: An unexpected case of Ramsay hunt syndrome: case report and literature review

Differential diagnosis Features
1/Bell’s palsy Bell’s palsy is a diagnosis of exclusion for unilateral facial weakness[17]. Erythematous vesicular rash and otalgia suggest Ramsay Hunt.
2/Otitis externa The ear pain in RHS can be mistaken for otitis[18]. Onset of rash and development of facial palsy differentiate Ramsay Hunt from otitis.
3/Trigeminal neuralgia Trigeminal neuralgia pain is similar to Ramsay Hunt but tends to be paroxysmal and stimulated by triggers. It is not associated with any skin manifestations or neurological losses[19].
