Dengue-Associated Myositis and Acute Kidney Injury in an Adolescent: A Rare Pediatric Complication

Dengue fever, an arthropod-borne viral illness, may have uncommon yet life-threatening complications, including neuromuscular manifestations such as myositis and rhabdomyolysis. We report a case of an adolescent male presenting with dengue-associated myositis complicated by rhabdomyolysis and acute kidney injury. Despite classical signs of rhabdomyolysis such as myalgia and tea-colored urine, urine myoglobin was undetectable, likely due to delayed presentation. Early recognition, supportive care, and corticosteroid therapy led to full recovery. This case emphasizes the importance of considering myositis and rhabdomyolysis in the differential diagnosis of muscle weakness in paediatric dengue patients and highlights the potential for renal complications.
