From hip pain to MAS: A case of gonococcal arthritis in a child

Area of Science:

• Pediatric Rheumatology
• Infectious Diseases
• Clinical Case Study

Background:

• Pediatric joint pain has a diverse range of causes, complicating diagnosis.
• Congenital cytomegalovirus (CMV) infection and hearing impairment can coexist with musculoskeletal issues in children.
• Gonococcal arthritis, caused by Neisseria gonorrhoeae, is uncommon in young children.

Purpose of the Study:

• To report a unique case of gonococcal hip arthritis in a pediatric patient with pre-existing conditions.
• To emphasize the importance of considering rare etiologies in the differential diagnosis of pediatric joint pain.
• To highlight the role of molecular testing in confirming diagnoses of unusual infections.

Main Methods:

• Detailed clinical presentation of a 3-year-old girl with thigh pain, fever, and gait disturbance.
• Extensive diagnostic workup including imaging (e.g., hip imaging) and laboratory tests.
• Molecular testing for confirmation of Neisseria gonorrhoeae infection.

Main Results:

• Diagnosis of gonococcal hip arthritis was confirmed in the patient.
• The patient had a history of bilateral hearing impairment and congenital CMV infection.
• Management involved multidisciplinary care and specific antimicrobial therapy.

Conclusions:

• This case underscores the need for a broad differential diagnosis in pediatric joint pain.
• Congenital infections and other health conditions should be considered in complex pediatric cases.
• Prompt and accurate diagnosis through comprehensive evaluation is vital for effective treatment of pediatric joint pain.
