Sternocleidomastoid pyomyositis

Abstract

Cervical pyomyositis is a rare condition that if not treated appropriately may cause internal jugular vein thrombosis, sepsis and death. Pyomyositis requires a high index of suspicion and should be considered a differential diagnosis in any painful swelling in the head and neck region.

“…Furthermore, GAS infection is a known complication of chicken pox in children [5], although only 1 of the 6 pediatric cases was GAS-positive. Although pyomyositis typically occurs in the lower extremities (9/24, 37.5%) [5, 9–27], other muscle groups can be involved, such as the iliac [10], psoas [11, 17], iliopsoas [11], trunk [5], neck [13, 18, 26, 27], and upper extremity muscles [14, 16, 19, 22, 25]. Involvement of multiple muscle groups is also common (9/24, 37.5%).…”

“…Treatment of pyomyositis consists of administration of antimicrobial agents and drainage of intramuscular abscesses. Empiric antimicrobial choice is primarily targeted to S aureus , which is the most common pathogen . However, because other pathogens such as Streptococci can be involved, a broad coverage of pathogens should be ensured until the actual pathogen is isolated.…”

However, because other pathogens such as Streptococci can be involved, a broad coverage of pathogens should be ensured until the actual pathogen is isolated. Drainage of pus can be achieved either by open surgery or by image‐guided needle aspiration .…”

“…However, because other pathogens such as Streptococci can be involved, a broad coverage of pathogens should be ensured until the actual pathogen is isolated. Drainage of pus can be achieved either by open surgery or by image‐guided needle aspiration . The selection of the technique depends on the location and size of the abscess.…”

“…This condition is likely to occur in immunocompromised individuals, and skeletal muscles around the hip and in the thigh are most frequently affected . Pyomyositis affecting the sternocleidomastoid muscle is rare, with only seven previously reported cases . An accurate diagnosis is difficult with physical examination alone, and imaging evaluation is required.…”
