“…A number of authors suggest that psoas abscess arises as a result of hematogenous dissemination in a manner analogous to acute osteomyelitis [9,19,21,40,49,57]. Trauma with hematoma formation may predispose to abscess development, especially if a distant source of infection is present [5,20,27,40,49,57,62].…”

“…The exact relationship of pyogenic psoas abscess to primary suppurative myositis, or tropical pyo-myositis [9,64,71,78] is unknown. Although uncommon in temperaturate areas [78], a number of similarities with psoas abscess are apparent.…”

“…Bacteremia in both conditions may be early and short-lived, thus going undetected; this might explain the low mortality rate with these infections compared to other staphylococcal bacteremias [78]. Trauma may also be a pathogenic factor in pyomyositis [9,27,78], although viral and parasitic infections have also been implicated [9,78]. Poor nutrition and low social status were thought to predispose patients to pyomyositis, but recent reports have doubted this [78].…”

Pyogenic abscess of the psoas muscle results from primary suppuration or direct extension of intraabdominal infection. The etiology varies with the country of origin. Our experience with 9 cases prompted a review of 367 cases from the world literature. A total of 286 primary abscesses occurred mainly in developing nations (200 cases), although 74 were reported from the United States. Younger patients predominated in developing nations (81.4% <20 years old), while only 47.8% from the United States were younger than 20 years. PureStaphylococcus aureus was commonly cultured (88.4%); simple incision and drainage cured 97.3% of patients with primary psoas abscess. Of 7 (2.5%) patients who died, 6 were from the United States; therapy was inadequate or delayed in all 7 patients. Ninety secondary abscesses appeared almost exclusively in reports from Europe, the United States, and Canada. Crohn's disease was the most common etiology followed by appendicitis and colon inflammation or cancer; mixed enteric infections predominated (55.7%). Although rare during the first decade, distribution was otherwise relatively even across all age groups. Simple drainage succeeded in only 49% of cases. Higher mortality accompanied secondary abscess (17 cases, 18.9%). The etiology of pyogenic psoas abscess guides the selection of proper medical and surgical therapy. While primary abscess is the likely etiology in developing nations and secondary abscess in Europe, either may occur in the United States. Early diagnosis and proper therapy are necessary to reduce mortality.

“…Computerized tomography is considered to be a most helpful tool for the diagnosis of pyomyositis (1,(12)(13)(14). It was particularly useful in our complicated case by showing the abscess formation before it became clinically apparent, and also by showing the extension into the spinal canal-thereby allowing an understanding of the clinical picture and an appropriate therapeutic approach, without further invasive and potentially hazardous procedures.…”

Non‐Tropical Pyomyositis in Children–with Report of Severe Neurological Complications

Pyomyositis appears to occur rarely in temperate climate areas, compared with the incidence of the disease in the tropics. Three young adults with pyomyositis have previously been described in Israel, two of them were newly arrived Ethiopian immigrants. We report three Israeli children with pyomyositis, who presented initially with nonspecific abdominal pain; in one child the course was complicated by spinal cord compression due to extension of the infected mass into the spinal canal. All three patients attained full recovery after antibiotic therapy and surgical drainage. Computed tomography was most valuable in establishing the diagnosis and defining the extent of the process.

“…RA is divided into two subtypes of primary and secondary [2]. The etiology of the primary subtype is not easily distinguishable; however, blood or lymphatics infection by an occult source could be the main cause of it [3]. The secondary infection is usually related to structures, such as psoas muscle, kidney, ureter, pancreas, large and small intestines, and iliac lymph nodes [1].…”

Background: Retroperitoneal Abscess (RA) is a rare and often insidious disease, i.e., difficult to diagnose. RA could originate from different retroperitoneal or intra-abdominal organs. The disease manifests various clinical symptoms and is usually treated with a combination of antibiotics and therapeutic interventions. Methods: Data from a total of 25 patients who were admitted to Loghman Hospital in Tehran City, Iran with a diagnosis of RA from 2010 to 2020 were reviewed in this research. Clinical findings, diagnostic tools, treatment approaches, and microbiology data were considered and analyzed. Results: Out of the 25 patients, the most frequent sources of RA were primary infections (36%), followed by gastrointestinal origin (20%). Fifty-two percent of patients presented no underlying disease; however, diabetes mellitus was the most prevalent underlying disease in the remaining ones. Fever, chills, and back or flank pain (56%) were the most common symptoms in the studied patients. Besides, a high erythrocyte sedimentation rate (mean: 93.58%) was found in most of the researched patients. Computed Tomography (CT) scan and Magnetic Resonance Imaging (MRI) could reliably diagnose the disease with an accuracy of 100% and 92.3%, respectively. Seventy-two percent of the study patients eventually underwent surgery. By taking advantage of CT scan, 24% of abscesses were drained and only 4% required medications to achieve remission. Mycobacteria and Klebsiella pneumonia were the most prevalent pathogens among the explored patients. The total mortality rate was equal to 12%; it occurred in cases with RA of a gastrointestinal (8%) or genitourinary (4%) origin. Conclusion: There exist 3 major choices for treating abscesses, including surgery, image-guided percutaneous drainage, and medical therapy. Image-Guided drainage is recommended in primary infections; however, extra-peritoneal surgery is useful to treat secondary infections, especially those of a gastrointestinal source.
