CASE REPORT ON RARE BILATERAL PAROTITIS SECONDARY TO MUMPS AND MONONUCLEOSIS

Dr. Sherin K. Moncy and *Dr. Joel Biju

ABSTRACT

Mumps, caused by rubulavirus, and mononucleosis, primarily resulting from Epstein-Barr virus (EBV) infection, represent distinct viral illnesses sharing overlapping clinical manifestations. This case report presents a 10-year-old male patient who exhibited symptoms suggestive of both conditions, including fever, vomiting, and bilateral parotid swelling. Despite vaccination efforts, breakthrough infections such as mumps persist, underscoring the complexity of achieving full immunity within the population. Concurrently, mononucleosis, characterized by pharyngitis, lymphadenopathy, and fatigue, presents diagnostic challenges due to its resemblance to mumps. This case report discusses a 10-year-old male presenting with fever, vomiting, and bilateral parotid swelling, ultimately diagnosed with concurrent mumps and mononucleosis from elevated inflammatory markers, prompting further diagnostic evaluation. Serological testing revealed mumps-specific immunoglobulin (IgM) and EBV IgM antibodies, confirming the coexistence of mumps and mononucleosis. Management strategies tailored to address symptoms and complications associated with both infections were implemented. The patient's clinical status improved following pharmacological interventions and supportive care. This case highlights the importance of meticulous diagnostic evaluation when encountering patients with overlapping symptoms suggestive of both mumps and mononucleosis. Moreover, it emphasizes the rarity and clinical significance of encountering both infections concurrently, as misdiagnoses can lead to inappropriate management strategies and potentially contribute to further spread. Comprehensive understanding and recognition of the distinct etiological origins and overlapping symptomatology of mumps and mononucleosis are essential for accurate diagnosis and optimal patient management.
