Bifid ribs are rare congenital anomalies, usually asymptomatic and discovered incidentally on imaging. However, they can cause significant pain, posing diagnostic and therapeutic challenges, particularly in pediatric populations. We report a case of a 3-year-old female with chronic anterior chest wall pain attributed to a bifid right fourth rib. Imaging confirmed the anomaly without associated soft tissue masses. After transient symptom relief with lidocaine patches and intercostal nerve blocks, she underwent successful percutaneous image-guided cryoneurolysis of the right third to fifth intercostal nerves. The patient experienced marked pain relief post-procedure without complications, with sustained benefit at 4 months. Bifid ribs may be an under-recognized cause of intercostal neuralgia in children. Image-guided percutaneous cryoneurolysis may represent a safe and effective treatment option for symptomatic relief.
