Plain-English summary
A 7-year-old American Quarter Horse gelding had a recurring swelling on his forehead that prompted a visit to the vet. After imaging, the vet found a piece of dead bone and an infection in the area. They performed surgery to remove the infected bone and clean the sinus, and a culture revealed a type of bacteria called Actinomyces. The horse was treated with an antibiotic for two weeks, and at a follow-up three months later, the swelling had completely resolved.

Abstract
A 7-year-old American Quarter Horse gelding was referred to the JT Vaughan Large Animal Teaching Hospital at Auburn University, College of Veterinary Medicine, for an investigation of a recurrent swelling of the nasofrontal region. Computed tomography examination of the skull was most consistent with a sequestrum of the left nasofrontal suture with associated focal osteomyelitis and left conchofrontal sinusitis. Surgery to remove the sequestrum, debride the devitalized bone, and flush the left conchofrontal sinus was performed. A microbial culture was obtained at the time of surgery, which yielded a mixed heavy growth of an Actinomyces species. Quantitative PCR indicated a species with 93% resemblance to Actinomyces funkei. A treatment course of two weeks of oral chloramphenicol was prescribed. At three-month follow-up, the owner reported resolution of the swelling.
