Epidemiological features and outcomes of patients with psoas abscess: A retrospective cohort study

Psoas abscess caused by Escherichia coli pyelonephritis, A Case Report

“…The iliopsoas is in close contact with the diaphragm, the kidneys, the renal vessels, the ureter and the sigmoid colon on the left and the caecum and appendix on the right. Due to the proximity of these adjacent structures, the iliopsoas is predisposed to infectious spreading originating from these sites [3] , [4] , [5] …”

“…Most abscesses (in Europe) are secondary, associated with infection of the hip joint (after hip arthroplasty), vascular structures (infected aortic aneurysm), vertebral discs and bodies (osteomyelitis or discitis), gastrointestinal (eg, Crohn's disease, colitis, appendicitis) or genitourinary tract (after renal surgery, pyelonephritis) (Table 1) [3 , 6] . A shift from tuberculosis and digestive diseases to skeletal pathology has been observed during the last decades [3 , 4] . Risk factors for primary abscess include renal failure, diabetes, HIV infection or other forms of immunosuppression whereas secondary abscesses are more seen after trauma or instrumentation in the hip region, lumbar spine or inguinal region [3 , 6] .…”

“…To confirm the diagnosis additional imaging is required. Computed tomography (CT) with and without IV contrast is considered as the modality of choice [4] . Abscesses typically present with a capsular ring enhancement on CT with contrast.…”

“…It must be noted that the optimal duration of the antibiotic therapy has yet to be determined. Currently two to six weeks of therapy following adequate drainage has been proposed [4 , 6 , 8 , 9] .

Intestinal neuronal dysplasia presenting as psoas abscess: A case report

“…The PA is mostly secondary abscess. The most common etiologies of PA were vertebral osteomyelitis, colorectal cancer, gastrointestinal tract infection and Crohn's Disease ( 11 , 12 ). Therefore, when the patient was admitted to the hospital, we first measured the tumor-related biomarkers, serum anti-tuberculosis antibodies and T-cell spot test for tuberculosis infection (T-TB.Spot).…”
