We report the case of a pediatric patient with transient synovitis of the hip as an initial atypical manifestation of a COVID-19 infection. A 7-year-old boy presented with gait disturbance, limping, and pain in his right hip. After 12 days, the patient continued with functional limitations and had associated symptoms such as fatigue and fever. Because of the atypical course, he was admitted to the hospital for joint aspiration. Due to institutional protocols, the preoperative evaluation included a COVID-19 PCR test. The joint aspiration sample showed clear synovial fluid with inflammatory characteristics and negative bacterial culture. COVID-19 PCR test results came out positive during the patient’s hospital stay. Clinical symptoms improved after the viral condition resolved. In the last follow-up, he was asymptomatic with a full hip range of motion. Transient synovitis of the hip could be an atypical initial symptom of a COVID-19 infection. Given the pandemic context of this disease, it is important to consider reactive arthritis as a consequence of this infection, especially in cases of atypical presentation, close family contact, fever, or other associated respiratory symptoms.
