Sternocleidomastoid pyomyositis is an exceptional pathology; multiple risk factors are involved in its development, such as chronic diseases or immunosuppression factors. It is rare, 0.4-1% of cases, immunodeficiency is a mainly predominant factor in these patients and is clinically characterized by evidence of a laterocervical tumor. The use of diagnostic imaging instruments is vital for timely treatment. The case of a 48-year-old male patient who came to the emergency service with a rapidly growing soft tissue cervical swelling is presented. He reported a medical history of type II diabetes mellitus of 8 years' duration, with poor therapeutic adherence. The radiology department was requested to perform an ultrasound and diagnostic tomography, observing an increase in volume of the right sternocleidomastoid muscle associated with the presence of a complex collection. He was taken for surgical drainage and biopsy, subsequently receiving broad-spectrum intravenous antibiotic treatment. After 4 days there was clinical improvement with a decrease in serological inflammatory markers. Histopathological findings reported edematous separation of muscle fibers, patchy myocytolysis and lymphoplasmacytic infiltration.
