Severe Costochondral Pain in a 16-year-old Female Patient

Costochondral pain can be a diagnostic challenge, especially following an acute disease. We present the case of a 16-year-old female patient who presented with developed severe costochondral pain following influenza A-related pneumonia. Despite initial treatment, her symptoms worsened, leading to significant impairment in her daily activities. Comprehensive investigations, including laboratory tests and imaging studies, were inconclusive. However, treatment with methylprednisolone led to a dramatic improvement in her symptoms. This case highlights the significance of considering inflammatory processes in the differential diagnosis of costochondral pain, especially in adolescents.
