“…Given the false-negative MRI results at the early stage of presentation, suspicion of disease based on physical findings and laboratory data is required to initiate early treatment. The most common bacterial organism is S. aureus, which includes methicillin-resistant SA (MRSA) in 62-90% of cases [6,[8][9][10]. Other organisms include Streptococcus pyogenes, Salmonella, Escherichia coli, and Pneumococcus.…”

A psoas abscess, a collection of pus in the psoas muscle, is rare but the incidence is increasing with the use of computed tomography (CT) and magnetic resonance imaging (MRI). Pyomyositis, a muscular infection that does not lead to abscess formation, is well known as tropical pyomyositis because it is highly prevalent in tropical areas. We encountered a case of iliopsoas pyomyositis and bacteremia without abscess formation. The blood culture was positive despite the early stage of presentation and no abscess formation on MRI. Imaging is the gold standard for diagnosing iliopsoas abscesses. There are cases similar to ours wherein the blood culture is positive before the formation of an abscess. Regardless of whether an abscess is found on MRI or not, we need to consider the possibility of false negatives at the early stage of presentation. A suspicion of this disease is essential during a physical examination for early diagnosis and treatment, especially in rural areas, where medical resources are limited. Furthermore, pyomyositis is a common disease in tropical regions, but in recent years, case reports of occurrences in temperate regions have increased. This case indicates the need to consider pyomyositis as a differential diagnosis of fever and hip joint pain even in temperate regions.

“…Trauma, injection drug use, malnutrition and concurrent infections have been associated with pyomyositis [ 2 ]. Staphylococcus aureus is by far the most common cause, accounting for 75-90% of reported cases [ 3 ]. Blood cultures are usually negative.…”

A 61-year-old woman presented to the emergency ward complaining of low back pain for a month. She had undergone several spinal surgeries and a right radical nephrectomy 30 years before. A few days earlier she was injected with an intramuscular painkiller in her right buttock. An abdominal CT scan revealed multiple abscesses in the psoas muscle and the right posterior abdominal wall, including cellulitis in the adjacent subcutaneous tissue and the injection site. A diagnosis of pyomyositis from subcutaneous dissemination was made, and intravenous cefazolin was initiated. After five days of favorable progress, treatment was switched to oral cefadroxil to complete four weeks, leading to full recovery.

“…The first stage is an invasive stage, involving muscle pain with oedema, low-grade fever and general malaise. 1 The second stage is a suppurative phase, where patients experience severe muscle tenderness and swelling, a high spike in fever and other severe systemic symptoms. During this stage, abscess formation is detectable, and it is when most cases are clinically diagnosed.…”

“…Pyomyositis is a pyogenic infection of skeletal muscle with the typical presentation of a localised abscess, which is mostly observed in tropical countries. It commonly affects patients with existing conditions such as diabetes mellitus, haematological malignancy, chronic renal failure, asplenia, HIV infection, autoimmune diseases and those receiving chemotherapy or immunosuppressive drugs 1 2. Pyomyositis is mostly caused by Staphylococcus aureus up to 90% of the cases.…”

Severe thoracic pyomyositis in a patient with systemic lupus erythematosus

Pyomyositis may mimic deep vein thrombosis and be misdiagnosed in patients with systemic lupus erythematosus (SLE). We report here on patient with SLE with severe thoracic pyomyositis presented with right upper arm swelling and fever. The patient fully recovered after a serial surgical debridement and antibiotic therapy. Pyomyositis, as well as deep vein thrombosis, should be considered during the differential diagnosis of patients with SLE experiencing fever and unilateral limb oedema. CT and identification of causal pathogens are crucial in the diagnosis of pyomyositis. Early effective antibiotic treatment as well as surgical intervention can together bring about a better outcome.
