Fibrous dysplasia (FD) is a benign bone tumor, which is prone to deformities, fractures, and results in pain. The etiology of FD has been linked to G protein mutation. FD can cause a wide spectrum of symptoms depending on the degree of involvement or comorbidity. We report a case of FD diagnosed at the pain clinic. A 37-year-old male visited the pain clinic with upper back and chest pain. The patient suffered from throbbing and burning sensation on his back for 12 years, and it has worsened since 3 years ago. We performed three times of erector spinae plane block at one-month interval and prescribed medications under the diagnosis of intercostal neuralgia. His pain improved over few weeks, however, the symptoms had a pattern of wax and wane with a numerical rating scale(0 = no pain, 10 = worst pain imaginable) ranging from 2 to 8 during the 6-month follow-up. We decided to perform chest CT and 3 phase bone scan(3PBS) concerned about potential lesions or malignancies. Chest CT and 3PBS showed recent and multiple old fracture of ribs, and a focal radioactive uptake in the right temporal skull. After discussing with a radiologist, thoracic and neuro-surgeon, his lesions were presumed as FD. We planned to continue managing of his pain, and will consider further multidisciplinary care if needed.
