A 54-year-old female with complex regional pain syndrome (CRPS) type 1 secondary to a motor vehicle accident presented to the hospital with a 2- to 3-week history of worsening generalized body pains seeking intravenous immunoglobulin (IVIG) infusion. At presentation, the patient also noted mouth dryness and pain radiating to her head, symptoms typical for her CRPS. Additionally, the patient later reported several months of increased multifocal pain with a particular focus in the region of the left upper palate. As the patient’s primary team searched for an appropriate immunomodulatory regimen to reduce the patient’s reliance on IVIG for analgesia, an oral maxillofacial surgery consult was obtained, and a contrast-enhanced maxillofacial computed tomography (CT) was subsequently ordered.
