RESUMEN
RATIONALE: Iliopsoas abscess is a rare acute medical condition. It usually occurs because of the spread of infection from adjacent structures and hematogenous spread. Clinical features include fever, backache, radiating nerve root pain, and leg weakness. When sepsis occurs, prompt recognition is required to initiate appropriate antimicrobial therapy and surgical drainage. PATIENT CONCERNS: A 65-year-old male presented to the outpatient department with a 2-day history of lower back, hip, and leg pain, for which analgesics were administered. During hospitalization, he experienced deterioration, becoming febrile, hypoxic, hypotensive, tachycardiac, and delirious. INTERVENTIONS: The patient was then intubated and ventilated. His family reported an additional history of acupuncture for back pain, which sustained an inflamed wound on his right forearm. Abdominal computed tomography was performed, which confirmed bilateral iliopsoas abscess without involvement of intra-abdominal organs. A preliminary report of blood culture revealed Gram-positive cocci. Echocardiography showed vegetation on the aortic valve, and moderate aortic regurgitation was sustained. He was started on vancomycin along with piperacillin-tazobactam. Ultrasound-guided percutaneous drainage was inserted into the bilateral abscess. Pus and blood yielded methicillin-sensitive Staphylococcus aureus. He remained septic. The repeat computed tomography showed the right abscess enlarged. A repeated echocardiogram showed that the vegetation increased. Further incision and surgical drainage were performed with continuous wash-out. OUTCOME: His condition improved after management and he was discharged to a regional hospital for ongoing care. CONCLUSION: Prompt diagnosis and surgical treatment are essential to improve patient outcomes. The unique aspect of this case is the persistence of the methicillin-sensitive Staphylococcus aureus infection. Centralized surgical services are pivotal in conjunction with robust antimicrobial regimens. LESSON: This case reinforces the importance of high clinical suspicion of an unknown source of sepsis.

BACKGROUND: Psoas abscess (PA) is an uncommon disease that has been increasingly reported in the recent years. We reviewed patients with PA and analyzed their clinical characteristics to improve our understanding of this rare disorder. METHODS: We retrospectively reviewed the clinical presentations, microbiology, and outcomes of patients with PA between 2011 and 2022 at the Zhejiang Provincial People's Hospital in China. RESULTS: There were 40 adult patients identified with the discharge diagnosis of PA. The mean age was 60 years, and 67.5% of the patients were male. Primary symptoms were typically nonspecific. In all, 20 abscesses were considered secondary, and the most common was infective spondylitis. The most common causative organism for primary PA was Staphylococcus aureus, followed by Escherichia coli, whereas multiple bacterial species were found in secondary abscesses. The overall in-hospital mortality rate was 5%. Patients with secondary PA had a longer hospital stay. CONCLUSION: PA, as a serious infectious condition, usually presents with nonspecific symptoms and laboratory test results, making early diagnosis difficult. These profiles differed from those reported in the present study. The initial clinical status and subsequent imaging studies can lead to favorable outcomes.

Treatment of spinal brucellosis with bilateral psoas abscess is a challenging clinical endeavor. We retrospectively evaluated a case of lumbar infection and bilateral psoas abscess, and was effectively managed through a unilateral extreme lateral approach with the aid of NPWT for bilateral drainage. We hypothesize that NPWT can influence the Piezo1 receptor of neutrophils and further influence the interaction between neutrophils and endothelial cells to promote the clearance of infected lesions, and this phenomenon is also observed in pathological slides. This proves that NPWT can rapidly enhance the recruitment of neutrophils in the infected area and improve the local immune response, and after a year of reassessment and tracking, Bilateral drainage using NPWT via a unilateral Extreme Lateral Approach could acquire satisfactory surgical outcomes, can be used as a treatment modality for lumbar infection with bilateral psoas abscesses.

BACKGROUND: Pott disease is rare and responsible for only 1%-2% of all tuberculosis cases. It poses diagnostic challenges in resource-limited settings due to unusual presentation and limited investigative capacity, resulting in debilitating sequelae if diagnosed late. CASE PRESENTATION: We present a case of severe Pott disease of the lumbar spine, with a large paravertebral abscess tracking down to the gluteal region in a 27-year-old Black African Ugandan woman living with human immunodeficiency virus, whose main complaint was right lower abdominal pain. She was initially misdiagnosed from the peripheral clinics as a case of lumbago and later with a psoas abscess. The diagnosis of severe Pott disease was established at the regional referral hospital following an abdominal computed tomography scan, and the patient was appropriately initiated on anti-tuberculosis drugs. However, only abscess drainage and provision of a lumbar corset were possible, with no neurosurgical intervention done on the spine due to financial constraints. Clinical review at 2, 6, and 12 months revealed improvement. CONCLUSIONS: Pott disease may present with non-specific symptoms such as abdominal pain resulting from pressure effects of an expansile cold abscess. This, coupled with limited diagnostic capacity in resource-limited settings; results in significant morbidity and possible mortality. Hence, there is need to train clinicians to increase their index of suspicion and equip health units with basic radiological equipment, such as x-ray, for timely detection and subsequent management of Pott disease.

Background: Abdominal stab wounds are common in clinical practice. However, the development of psoas muscle abscess following such an injury is extremely rare. Moreover, literature surrounding psoas muscle hematoma formation as a consequence of penetrating abdominal injury is scarce. Objective: We report a case of psoas abscess formation following the development of psoas hematoma in a patient who suffered from a penetrating abdominal injury. Case presentation: A 40-year-old Indian male presented to the Emergency department with multiple abdominal cut and stab wounds as a result of physical assault. A computed tomography scan revealed injuries to the ascending colon along with hemoperitoneum and right psoas muscle hematoma. Exploratory laparotomy was performed in which a right hemicolectomy and a right psoas muscle evacuation were successfully achieved along with multiple drainage tubes placed. Six days later, a peritoneal fluid culture tested positive, and a computed tomography scan revealed right psoas muscle collection which was diagnosed as an abscess. Treatment of the abscess included antibiotics and ultrasound-guided drainage. Patient was eventually discharged but was lost to follow-up. Conclusion: The development of iliopsoas abscess and hematoma as a consequence of abdominal penetrating injuries is a rare occurrence. Diagnosis can be made by computed tomography imaging and examination of the drained fluid. Managing a case with both of these rare phenomena can be challenging due to the scarce literature highlighting and comparing the different management modalities.

Infective endocarditis of the tricuspid valve is rare in non-intra-venous drug abusers. Few cases of psoas abscess complicated by tricuspid infective endocarditis have been reported. A 61-year-old man underwent a laminectomy. Three weeks later he developed persistent fever, abdominal pain, back pain and hip pain, weight loss, gradually and abdominal distension. Abdomino-thoracic computed tomographic scan showed a left psoas muscle abscess and cavitary pulmonary lesions suggestive of septic pulmonary emboli. Two dimensional transthoracic echocardiography showed an oscillating mass on the anterior leaflet of the tricuspid valve compatible with a vegetation. There was severe tricuspid regurgitation with right atrial and right ventricular dilatation. Secondary psoas abscess though rare is an important cause of bacteremia and there is a potential of bacteremia progressing to serious systemic infection like tricuspid endocarditis which can be fatal without prompt and appropriate treatment.

Infectious aortitis has various causes, presents mainly with an aneurysm, and is fatal without surgical intervention. This case report describes an 89-year-old woman who developed fever and back pain which initially diagnosed infectious aortitis confirmed through contrast-enhanced computed tomography (CT). Pyogenic spondylitis and psoas abscess, which were not visible through CT at admis-sion, were identified as the cause of infectious aortitis confirmed through positron emission tomography (PET). After percutaneous drainage and intravenous antibiotics, the patient was discharged in good condition and without surgical intervention. This case report emphasizes the critical role of PET in identifying the cause of infectious aortitis and demonstrates the effectiveness of successive treat-ment with antibiotics and timely radiologic intervention.

PURPOSE: To evaluate the feasibility and safety of the computed tomography (CT)-guided femoral approach for draining a psoas muscle abscess (PMA). MATERIALS AND METHODS: Between January 2014 and November 2018, the CT-guided femoral approach was employed for 9 abscesses in 8 patients who could not tolerate the prone position because of advanced age or other underlying conditions. A 17-gauge blunt metal needle was used to puncture the iliacus muscle below the groin under CT fluoroscopic guidance. A drainage catheter was then placed within the abscess cavity in the psoas major muscle. Technical success, clinical success, complications, the drainage therapy duration, susceptibility to antibiotics, survival, and recurrence were evaluated. RESULTS: The technical success rate was 100% among all nine lesions. The clinical success rate was 89% among all eight patients. One patient died of concomitant meningitis 15 days after the procedure. No patients developed therapy-related complications. The median duration of the drainage therapy was 15 days (range 6-71 days). Appropriate antibiotics based on the culture susceptibility were achieved in all patients. Four patients survived, and the remaining four died at 15 to 758 days (median, 36 days) after the procedure; no therapy-related deaths occurred. No recurrence was seen. CONCLUSION: The CT-guided femoral approach seems feasible, effective, and safe for draining psoas muscle abscesses in ill patients who cannot tolerate the prone position.

BACKGROUND: This study aimed to determine the indications for drainage in extended haematogenous iliopsoas abscesses (IPAs), which include both primary and vertebral osteomyelitis-related IPAs. METHODS: Sixty-three IPA patients who were initially treated with only antibiotics and no drainage were enrolled. The success (S) group included patients who were cured without drainage, while the failure (F) group included those who required open or percutaneous drainage or died. RESULTS: Compared with patients in the S group, patients in the F group (n = 15) had a higher incidence of end-stage renal disease on hemodialysis, compromised immunity, vertebral osteomyelitis of the cervicothoracic spine, other musculoskeletal infections, and multilocular abscesses. The IPAs in the F group had larger transverse and longitudinal diameters. In receiver operating characteristic curve analyses for the diameter of IPAs, the most valuable cut-off points predicting the F group were a longitudinal diameter of 5.0 cm (sensitivity, 1.0; specificity, 0.67) and a transverse diameter of 2.3 cm (sensitivity, 0.73; specificity, 0.73). A combination of both diameter cut-offs had high specificity (sensitivity, 0.73; specificity, 0.90). CONCLUSIONS: Drainage should be applied in case of a larger abscess with transverse diameter ≥ 2.3 cm and longitudinal diameter ≥ 5.0 cm. Conversely, IPAs with longitudinal diameter <5 cm do not require drainage. Haemodialysis, compromised immunity, vertebral osteomyelitis of the cervicothoracic spine, and musculoskeletal infections are risk factors of conservative treatment failure.

INTRODUCTION: The most common microorganisms isolated from septic arthritis are staphylococcus aureus and streptoccocci. Septic arthritis due to Salmonella spp. is extremely rare. PRESENTATION OF CASE: A 55-year-old man, chronic renal failure, is admitted hip arthtritis with newly arised symptoms. The findings were not compatible with primary arthritis. The laboratory findings which include white blood cell count, erythrocyte sedimentation rate (esr) and c-reactive protein (crp) were elevated. In magnetic resonance (mr) imaging there were psoas abscess and septic arthritis of the hip. They were treated by drainage. The culture was confirmed as Salmonella spp. Antibiotic treatment were done. DISCUSSION: Uremia in patients with chronic renal failure is associated with a state of immune dysfunction. In our case, uremia may cause immunosuppressive conditions and hematogenous dissemination of salmonella. CONCLUSION: Salmonella infection in a patient with chronic renal failure may be occured. It must be kept in mind that early diagnosis, administration of appropriate systemic antibiotics and surgical intervention play a pivotal role in successful management. KEY WORDS: Arthritis, Failure, Psoas, Salmonella Renal Abscess.

Primary iliopsoas abscess (IPA) in infants is an uncommon condition. It presents as inguinal or thigh swelling with limitation of movements on the affected side. Early detection and timely drainage of the abscess can prevent serious complications related to the dissemination of infection. We report a case of primary IPA due to methicillin-sensitive staphylococcal infection presenting as a left lumbar mass in an immune-competent infant. The abscess was detected in time, drained surgically and treated with cloxacillin for 4 weeks, thereby preventing serious complications.

Psoas abscess is a rare and occasionally life-threatening condition. In the past, the major cause of psoas abscess was a descending infection originating from spine tuberculosis (Pott's disease). Subsequently, secondary infection from spondylodiscitis or Crohn's disease has become the prevalent aetiology. Conventional treatment ranges from antibiotic therapy alone to CT-guided and/or surgical drainage. We present the case of a 67-year-old man with a complex history, including pneumonia, sepsis and previous muscle-skeletal trauma. The patient subsequently developed a psoas abscess that was successfully treated with a minimally invasive retroperitoneoscopic approach and antibiotics. Blood cultures and pus yielded Gram-positive Streptococcus sp, and transesophageal echocardiography identified endocarditis as a possible source of sepsis. Postoperative clinical course was complicated by recurrent sepsis that required a change of antibiotic therapy. The patient was eventually discharged to rehabilitation care without further complications. The retroperitoneoscopic approach is safe and effective for the treatment of cryptogenic psoas abscess.

BACKGROUND: Infections of the spine and hip joint are not common and, as described in literature, they are occasionally linked by a psoas abscess. In patients suffering back pain with history of spondylodiscitis, the spine as primary source of infection for a secondary psoas abscess should always be included in differential diagnosis. A delay in diagnosis of the psoas abscess could lead to septic femoral head necrosis. CASE REPORT: A case of a 65-year-old woman affected by septic femoral head necrosis due to spondylodiscitis and secondary psoas abscess is reported; the patient needed a specific antibiotic therapy then undergoing a total hip arthroplasty(THA). DISCUSSION AND CONCLUSION: Diagnoses of lumbar spine infection and psoas abscess are difficultand often delayed. Since the symptoms of both are non-specific, high degree of suspicious is necessary. In psoas abscess, an early diagnosis is important, because a delayed treatment could result in septic femoral head necrosis requiring both a prolonged antibiotic therapy and a THA.

OBJECTIVE: To determine clinical profile of osteoarticular tuberculosis (TB) in children. METHODS: Cross-sectional analysis from 2007 to 2013. All patients diagnosed with bone TB, spinal TB or TB abscesses were included. RESULTS: Out of 1318 children with TB, 39 (2.96%) had osteoarticular TB, of which 16 (42%) had osteomyelitis, 8 (20.5%) had spinal involvement, 7 (17.9%) had TB synovitis, 2 (5.1%) had psoas abscess and 6 (15.4%) had abscesses. The mean age of presentation was 7.1 ± 3.5 years (range 2-14 years). Of the 33 cases in which a culture was done, 25 (64%) showed a positive culture. Drug sensitivity tests were done in 21 patients of which 10 (47.6%) tested were drug resistant, of which 4 (36.4%) were multidrug resistant (MDR), 2 (18.2%) were extensively drug resistant (XDR), 3 were pre-XDR (27.3%) and 1 was polyresistant (9.1%). Nine (23.1%) patients had TB in the past with a treatment duration of 8.3 ± 5.3 months. Contact with a TB patient had occurred in 10 (25.6%) cases. Associated pulmonary TB were seen in 6 (15.39%) and TB meningitis were seen in 1 (2.6%) patients. Surgical intervention was needed in 11 (28.2%) patients of which 5 (45.5%) underwent curettage, drainage was done in 1 (9.1%), arthrotomy in 4 (36.4%) and spinal surgery in 1 (9.1%) patient. CONCLUSION: Drug resistant osteoarticular TB is an emerging problem in children.

BACKGROUND: Iliopsoas abscess (IPA) is a rare clinical entity and is difficult to diagnose due to its insidious onset and nonspecific symptoms. The association between IPA and cardiovascular disorders (CVD) has been rarely reported. Computed tomographic (CT) scan can provide a definitive diagnosis of IPA and associated foci of adjacent structures. IPA is a life-threatening condition, especially when associated with CVD. MATERIALS AND METHODS: We conducted a hospital-based observational study of IPA associated with CVD. Data were collected from the electronic clinical database of Taichung Veterans General Hospital (1520-bed tertiary referral hospital in central Taiwan) between July 2007 and December 2017. The diagnosis of IPA associated with CVD was confirmed by classical findings on CT and transesophageal echocardiography with compatible clinical presentation and cultures from pus/tissue and blood. RESULTS: Fifteen patients of IPA associated with CVD were studied. They included 12 males (80%) and 3 females (20%), with a mean age 63.2 ± 16.9 years (31-85 years). CVD included stent-graft/endograft infection of abdominal aortic aneurysm (AAA) (40%), primary mycotic AAA (33.3%), and infective endocarditis (26.7%). Staphylococcus aureus is the most common microorganism in pus/tissue cultures (n = 3, 37.5%) and in blood cultures (n = 6, 40%). The average length of hospital stay was 33.1 ± 20.5 days (range, 3-81 days; median, 33 days). Hospital stay lasted 42.6 ± 19.2 days in the survival group and 19.0 ± 14.1 days (P = 0.018) in the non-survival group. Incidence of patients staying in the intensive care unit (ICU) with intubation > 3 days was 33% in the survival group and 100% (P = 0.028) in the non-survival group. Intra-hospital mortality rate was 40%. Poor prognostic factors in the non-survival group were hypoalbuminemia, hyponatremia, involved disc/vertebral body and/or epidural abscess, and ICU stay with intubation > 3 days. Cumulative survival rate was 25% under conservative treatments and 66.3% under aggressive treatments (P = 0.038). CONCLUSION: Due to high mortality rates, clinicians should keep a high suspicion index for IPA associated with CVD through clinical presentation, physical examination, and imaging study. Timely empiric antibiotics for common bacteria, drainage for IPA, endovascular repair, or vascular reconstruction by graft replacement or bypass with intensive care should be mandatory to shorten the hospital stay, reduce medical costs, and lower mortality rate.

Iliopsoas abscess (IPA) is rare in children but exceptional in neonates. Fewer than 30 cases have been reported in literature. We present a case of 11-day neonate who was brought with left inguinal swelling along with significantly raised white cell count and positive C-reactive protein (CRP). Ultrasound and CT scan confirmed the diagnosis of IPA. Drainage of abscess was done by open method through extraperitoneal approach. Systemic antibiotics, according to culture and sensitivity, were given and the neonate recovered well and was sent home. IPA can be primary or secondary. Primary IPA is more common in neonates unlike adults, who have secondary IPA in majority of the cases. Primary IPA spreads by hematogenous route from distant occult source in the body. Staphylococcus aureus is the causative organism in most cases of primary IPA. Septic arthritis of hip joint is among important differentials. Ultrasound and CT scan are helpful in diagnosis in the presence of raised white cell count and positive CRP. Drainage of pus by open method and through extraperitoneal approach is preferred method although ultrasound-guided percutaneous drainage has also been done with successful outcome. In conclusion, neonatal IPA is extremely rare entity and can easily be overlooked. High index of suspicion is required for its diagnosis in cases where a neonate presents with groin swelling, limited or painful motion of leg and fever.
