Mumps Differential Diagnoses

Diagnostic Considerations
Approximately 10% of all infected patients develop a mild form of aseptic meningitis, which clinically can be confused with bacterial meningitis. Encephalitis, transient myelitis, and polyneuritis are rare.
A study investigated the difficulty in definitive mumps diagnosis, noting that only 14% of 2082 cases occurring during an outbreak were laboratory confirmed.[18] The study concluded that the clinical acumen for mumps diagnosis, based solely on clinical presentation, is low.
Conditions to be considered in the differential diagnosis of mumps include the following:
- Viral pathologies (ie, uveoparotid fever, coxsackievirus, influenza A virus, parainfluenza virus, cytomegalovirus, adenovirus, Epstein-Barr virus, varicella-zoster virus)
- Suppurative (bacterial, especially Staphylococcus aureus) or recurrent parotitis
- Parotid calculus
- Parotitis (different etiologies)
- Mixed tumors, hemangiomas, lymphangiomas of the parotid gland
- Calculus of the Stensen duct
- Adenitis (cervical lymphadenitis)
- Mastoiditis
- Orchitis
- Epididymitis
- Ovarian Torsion
- Mikulicz syndrome
- Sjögren Syndrome
- Drug reactions (thiazide diuretics)
- Allergic reaction (rare)
