A large iliopsoas abscess due to colon cancer complicated by bowel obstruction: A case report. Int J Surg Case Rep 2024; 117:109449. [PMID: 38452639 PMCID: PMC10926289 DOI: 10.1016/j.ijscr.2024.109449] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 02/20/2024] [Accepted: 02/22/2024] [Indexed: 03/09/2024] Open
Abstract
INTRODUCTION Iliopsoas abscesses (IPAs) associated with bowel obstruction due to colon cancer are rare, and there is no consensus regarding treatment strategies. PRESENTATION OF CASE A 63-year-old man presented with swelling and pain in the right iliac region. Imaging studies revealed an IPA expanding from the psoas major muscle and retroperitoneal space subcutaneously around the right ilium. After percutaneous drainage, the patient developed bowel obstruction secondary to colon cancer. Hemicolectomy and preventive ileostomy were performed at the gastrointestinal surgery department, and chemotherapy was administered at the medical oncology department after ileostomy closure. Three months later, local recurrence was confirmed in the right iliac region, and the recurrent lesion, including the ilium, was widely resected. One and a half years after the reoperation, there was no recurrence. DISCUSSION An IPA due to colorectal cancer without obvious perforation can also occur, and the treatment of IPAs depends on their size, location, shape, and presence of gas. Minimally invasive and staged treatment is preferable for IPAs due to colorectal cancer because the surgical mortality rate for colorectal cancer with local abscesses is high. CONCLUSION Colorectal cancer should be considered as a cause of IPAs. Treatment of IPAs caused by colon cancer should be performed in a less invasive manner after considering their size, location, shape, and the presence of gas. Cooperation between gastrointestinal surgeons and oncologists is essential for managing patients with an IPA due to colon cancer complicated by bowel obstruction.

Delayed iliopsoas abscess following COVID-19 pneumonia. Respir Investig 2024; 62:66-68. [PMID: 37951084 DOI: 10.1016/j.resinv.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 10/06/2023] [Accepted: 10/09/2023] [Indexed: 11/13/2023]
Abstract
Bacterial co-infection has been reported to contribute to a poor prognosis in patients with COVID-19. However, iliopsoas abscess (IPA) has not been previously reported as a comorbidity during the course of COVID-19. We report two cases of IPA in patients with COVID-19 pneumonia. Both patients required prolonged immunosuppressive therapy for COVID-19 pneumonia and developed bacteremia due to Serratia marcescens in one and Staphylococcus aureus in the other. Although immunosuppressive therapy is commonly used for COVID-19 pneumonia with hypoxemia, the comorbidity of IPA may have been underestimated in these cases.

A case of lymphoma mimicking infected internal iliac artery aneurysm. Surg Case Rep 2023; 9:84. [PMID: 37199823 DOI: 10.1186/s40792-023-01665-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 05/09/2023] [Indexed: 05/19/2023] Open
Abstract
BACKGROUND Malignant lymphoma rarely mimics an infected arterial aneurysm and a ruptured arterial aneurysm because of similar imaging findings, leading to misdiagnosis. The hematomas of ruptured aneurysms are radiologically difficult to distinguish from those of malignant lymphoma in emergency settings. Hence, a definitive diagnosis is crucial to avoid unnecessary surgery. CASE PRESENTATION A man in his 80s with hematuria and shock vital had right internal iliac artery aneurysm (IIAA) and perianeurysmal fluid retention, which appeared to be a ruptured or an infected aneurysm. Treatment was initiated for infected IIAA instead of for ruptured IIAA. Systemic inflammatory response syndrome developed, and the infectious sources were assessed. Pacemaker lead and urinary tract infections were identified and treated; however, blood pressure was unstable. The aneurysm was treated with endovascular aortic aneurysm repair following antibiotic therapy; however, fluid retention increased, and inflammatory status and hematuria deteriorated. Open surgical conversion was performed to manage the infected lesions. Although an iliopsoas abscess was detected during surgery and nephrectomy and ureterectomy were performed to control the hematuria, analysis of the removed tissues led to the pathological diagnosis of diffuse large B-cell lymphoma (DLBCL). CONCLUSIONS We encountered a case of DLBCL with imaging findings mimicking an infected internal iliac artery aneurysm, and definitive diagnosis was made more than 2 months after the initial examination. Definitively diagnosing malignant lymphoma around an iliac artery aneurysm based merely on symptoms and imaging findings is extremely difficult. Thus, histological examination should be actively performed in atypical infected aneurysms.

Emphysematous cystitis, iliopsoas abscess, and pneumorrhachis in an elderly woman: a case report. J Med Case Rep 2023; 17:150. [PMID: 37032335 PMCID: PMC10084606 DOI: 10.1186/s13256-023-03856-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 02/27/2023] [Indexed: 04/11/2023] Open
Abstract
BACKGROUND Emphysematous cystitis is a well-described life threatening complication of urinary tract infection, most commonly seen in patients with diabetes and typically caused by gas forming bacterial or fungal pathogens. Pneumorrhachis is the rare finding of gas within the spinal canal, most commonly reported in the context of cerebrospinal fluid leakage secondary to trauma or spinal instrumentation. To our knowledge there is only one other reported case of pneumorrhachis in the setting of emphysematous cystitis. CASE PRESENTATION This is a single case report of pneumorrhachis in the setting of emphysematous cystitis. An 82-year-old Asian female patient originally from East Asia, with no prior medical history besides hypertension, presented to hospital with a chief complaint of acute on chronic neck pain and functional decline. Examination revealed nonspecific neurosensory deficits and suprapubic tenderness. Laboratory investigations demonstrated leukocytosis and extended-spectrum beta-lactamase containing Escherichia coli bacteremia and bacteriuria. Computed tomography showed emphysematous cystitis with widespread gas within the cervical and lumbar spinal canal, as well as multiple gas-containing soft tissue collections in the bilateral psoas muscles and paraspinal soft tissues. Despite prompt antimicrobial therapy the patient passed away within 48 hours from septic shock. CONCLUSIONS Our case adds to a growing body of literature showing that the spread of air to distant sites, including the spine, may be a poor prognostic indicator in patients with gangrenous intraabdominal infections. This report highlights the importance of recognizing the causes and presentation of pneumorrhachis to facilitate early diagnosis and treatment of potentially life threatening and treatable causes.

A rare presentation of iliopsoas abscess - A case report. Int J Surg Case Rep 2022; 102:107832. [PMID: 36512883 PMCID: PMC9761371 DOI: 10.1016/j.ijscr.2022.107832] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/30/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022] Open
Abstract
INTRODUCTION Psoas abscesses are usually confined to the psoas compartment due to its fascial attachments. However, in rare situations, the infection can locally spread beyond the psoas sheath. CASE PRESENTATION A 65-year-old patient presented with; 3 weeks of lower back and right hip pain, progressive inability to walk and one week of urinary incontinence. CT abdomen showed a right psoas abscess with pneumo-retroperitoneum extending to the right gluteus muscle, posterior compartment of the upper thigh and mediastinum. Exploration in theatre showed copious amounts of pus, visible between the fascial layers and muscles of the thigh, tracking to the level of the knee and the gluteal region. DISCUSSION Psoas abscesses are usually confined to the psoas compartment. However, in this case, it was spread to the posterior compartment of the thigh, gluteal region and pelvis with fascial necrosis and pus. Due to the extensive nature of the disease and the patient's clinical deterioration, he underwent open drainage of the psoas abscess, exploration and debridement of the posterior compartment of thigh and gluteal region with a good outcome. CONCLUSION Psoas abscesses can penetrate the psoas sheath to cause extra pelvic extension. A high index of suspicion and early imaging, if necessary, should be arranged if in doubt. Depending on the clinical severity, patients may need to be managed with open drainage and debridement than conventional CT-guided drainage.

Abstract
Pyometra is a rare disease in which pus accumulates in the uterus and is typically caused by stenosis of the cervix. Only a few case reports have indicated that diverticular disease causes pyometra. We herein report an 83-year-old woman presented to our hospital with a fever, loss of appetite, general fatigue and back pain. After some inspections, she was diagnosed with pyometra and lumbar pyogenic spondylitis secondary to diverticulitis of the sigmoid colon. We performed transvaginal drainage and continued antibiotic administration for about three months. The pyometra and pyogenic spondylitis successfully resolved, and she did not experience any recurrence.

Abstract
INTRODUCTION AND IMPORTANCE Iliopsoas abscesses (IPA) are rare and typically present with a non-specific triad of fever, back pain, and antalgic gait. Staphylococcus aureus is the organism responsible for nearly 90 % of IPA cases. We present a case of primary IPA with progression to osteomyelitis and discitis due to Salmonella enterica bacteremia, an exceedingly rare etiology occurring in an otherwise healthy individual. CASE PRESENTATION This patient presented with fever, back pain, and hip pain. Initial imaging and laboratory workup did not reveal any source of infection. He became septic within 72 h of admission, and blood cultures were confirmed as Salmonella enterica. However, the etiology of the infection remained unclear. Computed Tomography (CT) imaging revealed a right-sided psoas abscess measuring 7 mm × 7 mm and an epidural phlegmon. He was discharged home with intravenous ceftriaxone and levofloxacin. However, the patient was readmitted due to L2-L3 osteomyelitis and discitis with an eccentric disc bulge causing compression of the right L3 nerve root and neutropenia. CLINICAL DISCUSSION This case in unique in the fact that this occurred in a healthy patient with no significant risk factors or exposure to this bacteria. Additionally, this case highlights the rapid progression of IPA and the spread to adjacent spinal structures with the potential to cause nerve compression with successful medical management. CONCLUSION Salmonella enterica is rare cause of iliopsoas abscess. This case emphasizes the importance of including iliopsoas abscesses as a differential diagnosis in patients with a high index of clinical suspicion.

Abstract
BACKGROUND Iliopsoas muscle abscess (IPA) and spondylodiscitis are two clinical conditions often related to atypical presentation and challenging management. They are both frequently related to underlying conditions, such as immunosuppression, and in many cases they are combined. IPA can be primary due to the hematogenous spread of a microorganism to the muscle or secondary from a direct expansion of an inflammatory process, including spondylodiscitis. Computed tomography-guided percutaneous drainage has been established in the current management of this condition.
AIM To present a retrospective analysis of a series of 8 immunocompromised patients suffering from spondylodiscitis complicated with IPA and treated with percutaneous computed tomography-guided drainage and drain insertion in an outpatient setting.
METHODS Patient demographics, clinical presentation, underlying conditions, isolated microorganisms, antibiotic regimes used, abscess size, days until the withdrawal of the catheter, and final treatment outcomes were recorded and analyzed.
RESULTS All patients presented with night back pain and local stiffness with no fever. The laboratory tests revealed elevated inflammatory markers. Radiological findings of spondylodiscitis with unilateral or bilateral IPA were present in all cases. Staphylococcus aureus was isolated in 3 patients and Mycobacterium tuberculosis in 2 patients. Negative cultures were found in the remaining 3 patients. The treatment protocol included percutaneous computed tomography-guided abscess drainage and drain insertion along with a course of targeted or empiric antibiotic therapy. All procedures were done in an outpatient setting with no need for patient hospitalization.
CONCLUSION The minimally invasive outpatient management of IPA is a safe and effective approach with a high success rate and low morbidity.

Abstract
Iliopsoas abscess (IPA) is uncommon condition in children, diagnosis might be delayed because of nonspecific signs and symptoms. Only few patients have classical clinical triad at presentation in the form of fever, back pain, and inguinal pain at hip flexion. The diagnosis most likely to be reached in the first time by the use of abdominal computed tomography (CT) scan. We present a Saudi child with nonspecific signs and symptoms of fever, flank pain, and limping who was diagnosed as IPA by abdominal ultrasound and CT scan. The case was managed with intravenous antibiotics along with transcutaneous abscess drainage.

Abstract
A 77-year-old African American female with rheumatoid arthritis presented with fever and unsteady gait. She was started on broad-spectrum antimicrobials due to CT evidence for sacroiliitis and psoas abscess and underwent partial excision of her sacroiliac bone and drainage of the abscess. One of four blood cultures grew Enterococcus faecalis and the patient was sent home with intravenous ampicillin for 6 weeks. Two days after antimicrobial completion, the patient presented with night sweats and weakness. Chest x-ray revealed new right upper lobe pulmonary infiltrates, and the AFB culture sent during her prior admission returned positive for TB. RIPE therapy with moxifloxacin was initiated. Although she responded well to treatment, she retained functional immobility. We report a case of musculoskeletal TB initially misdiagnosed as enterococcus sacroiliitis, resulting in a delayed initiation of anti-tuberculous therapy. A high index of suspicion and rapid detection with TB-PCR testing should be considered to avoid delayed diagnosis.

Abstract
An 83-year-old man visited an orthopedic hospital for his lower back pain. A compression fracture was noted in his second lumbar vertebra. He had taken pain medication for approximately five weeks, but the pain had worsened and he was unable to walk by himself. He was transferred to our hospital and diagnosed with lumbar spondylodiscitis, an iliopsoas abscess, gas gangrene of his left lower limb, and left massive pleural effusion. He was admitted to the intensive care unit. We drained the abscess and pleural effusion, provided continuous hemodiafiltration under ventilator control, and administered intravenous antibiotics. However, he died from sepsis and multiple organ failure three days following admission. Several days after his death, gram-positive cocci were identified in blood culture, pus from the abscess, and pleural exudate; although the causative organism could not be identified. Two weeks subsequent to his death, 16S ribosomal RNA gene sequencing identified Parvimonas micra in specimens taken from his body.

Abstract
Intestinal metastases from colorectal cancer typically occur by intraperitoneal spread, whereas those occurring via hematogenous route are exceedingly rare. We report a case of intestinal metastases from sigmoid colon cancer that presented as iliopsoas abscess and ileus. A 78-year-old man who had undergone sigmoidectomy for sigmoid colon cancer 5 years ago was referred to our hospital with recurrent ileus and fever. Abdominal computed tomography showed a left iliopsoas abscess and a mass near the abscess that had ostensibly caused ileus. The patient underwent segmental resection of the jejunum including the mass. Histopathological examination of the resected specimen revealed moderately differentiated adenocarcinoma proliferating mainly in the submucosal and muscular layers, which was pathologically identical to the colon cancer resected 5 years ago. He died 18 months after the surgery because of liver metastases. This case report highlights the delayed occurrence of colorectal metastases at unusual sites, such as the small bowel, more than 5 years after the resection of the primary cancer. Intestinal metastases should be considered in patients with a history of colon cancer, particularly in those with recurrent ileus or abdominal abscess with no obvious cause.

Abstract
Iliopsoas abscess in HD patients is rare. We examined nine HD patients with iliopsoas abscess (six men and five diabetes mellitus cases) treated between 2005 and 2015. Mean age and dialysis vintage at onset were 72 years and 109 months, respectively. Of the nine patients, four had lumbar orthopedic diseases, and two had all components of the classic triad of iliopsoas abscess at onset. All nine patients underwent percutaneous drainage, while seven underwent antimicrobial therapy. The most common pathogenic bacterium was methicillin-resistantStaphylococcus aureus(MRSA) (n = 5). Four patients had multilocular recurrence on the same side as the initial abscess and did not undergo CT before drainage catheter removal. Five patients died in the hospital, in which three died due to infectious diseases by MRSA. We suggest percutaneous drainage as the first-line therapy for HD patients with iliopsoas abscess and recommend combining antimicrobial therapy for MRSA, because of poor prognosis.

Abstract
Background Iliopsoas abscess is a collection of pus in the iliopsoas muscle compartment. It can be primary or secondary in origin. Primary iliopsoas abscess occurs as a result of hematogenous or lymphatic seeding from a distant site. This is commonly associated with a chronic immunocompromised state and tends to occur in children and young adults. Secondary iliopsoas abscess occurs as a result of the direct spread of infection to the psoas muscle from an adjacent structure, and this may be associated with trauma and instrumentation in the inguinal region, lumbar spine, or hip region. The incidence of iliopsoas abscess is rare and often the diagnosis is delayed because of non-specific presenting symptoms. Case presentation We describe a patient with iliopsoas abscess who presented to the Emergency Department at X Hospital on three separate occasions with non-specific symptoms of thigh pain and fever before finally being admitted for treatment. This case illustrates how the diagnosis can be delayed due to its atypical presentation. Hence, highlighting the need for clinicians to have a high index of clinical suspicion for iliopsoas abscess in patients presenting with thigh pain and fever. Conclusion The classic triad of fever, flank pain, and hip movement limitation is presented in only 30% of patients with iliopsoas abscess. Clinicians should consider iliopsoas abscess as a differential diagnosis in patients presenting with fever and thigh pain. The rare condition with the varied clinical presentation means that cross-sectional imaging should be considered early to reduce the risk of fulminant sepsis.

Abstract
Primary abscess of the iliopsoas muscle in children is uncommon, especially due to Streptococcus pyogenes (group A streptococcus: GAS), which causes a variety of diseases ranging from pharyngitis to invasive life-threatening infection. We present primary iliopsoas abscess in a nine-year-old boy presenting with fever, mild disturbance of consciousness, limp, and pain in the right loin. Magnetic resonance imaging and isolation of GAS from both blood and abscess samples led us to the confirmative diagnosis. The patient recovered after treatment comprising drainage and intravenous antibiotics. The CovRS system is one of the best-characterized systems with two-component signal transduction in the GAS, and mutations in covRS induce overproduction of various virulence factors that play a crucial role in invasive GAS infection. RopB, also known as a GAS regulator, influences the expression of multiple regulatory networks to coregulate virulence factor expression in GAS. In the present case, sequence analysis revealed the isolated GAS as emm type 6 with alterations in covS, whereas the covR and ropB genes were intact. The covS alterations might have influenced the virulence of the strain causing this severe GAS infection.

Abstract
Iliopsoas abscess (IPA) is an uncommon infection. The clinical presentation is usually insidious. Most patients present with nonspecific symptoms, leading to difficulty in prompt and accurate diagnosis. Delay in diagnosis can lead to complications, such as sepsis and death. Tattooing has become more popular over the recent years and has been associated with tattooing-related and blood-borne infections. We present two related cases of methicillin-resistant Staphylococcus aureus IPA after tattooing and review the epidemiology, etiology, clinical features, and management of IPA.

Iliopsoas abscess as a complication of tunneled jugular vein catheterization in a hemodialysis patient. Hemodial Int 2014; 19:330-2.

Abstract
Iliopsoas abscess is a rare complication in hemodialysis patients that is mainly due to adjacent catheterization, local acupuncture, discitis, and bacteremia. Herein, we report a 47-year-old woman undergoing regular hemodialysis via a catheter in the internal jugular vein who presented with low back pain and dyspnea. A heart murmur suggested the presence of catheter-related endocarditis, and this was confirmed by an echocardiogram and a blood culture of methicillin-resistant Staphylococcus aureus. A computed tomography indicated a pulmonary embolism and an incidental finding of iliopsoas abscess. Following surgical intervention and intravenous daptomycin, the patient experienced full recovery and a return to usual activities. This case indicates that an iliopsoas abscess can be related to a jugular vein catheter, which is apparently facilitated by infective endocarditis. The possibility of iliopsoas abscess should be considered when a hemodialysis patient presents with severe low back pain, even when there is no history of adjacent mechanical intervention.

Lemierre's disease: a case with bilateral iliopsoas abscesses and a literature review. World J Emerg Surg 2014; 9:38. [PMID: 24904685 PMCID: PMC4046005 DOI: 10.1186/1749-7922-9-38] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2014] [Accepted: 04/17/2014] [Indexed: 12/05/2022] Open
Abstract
Lemierre's disease is characterized by sepsis, often with an oropharyngeal source, secondary septic emboli and internal jugular vein thrombosis (Lancet 1:701-3, 1936. Clin Microbiol Rev 20(4):622-59, 2007). Septic emboli affecting many bodily sites have been reported, including the lungs, joints, bones, and brain. The case report describes an unusual case of Lemierre's disease in a 64 year old gentleman causing profound sepsis, acute kidney injury, bilateral iliopsoas abscesses and a right hand abscess. To our knowledge, this is the first reported case of Lemierre's disease in the context of bilateral psoas abscesses, and highlights the ambiguity surrounding the definition of Lemierre's disease. The clinical literature review highlights the difficulty in definitively diagnosing the condition and offers some suggestions for recognising and refining the diagnostic criterion of Lemierre's.

Pneumorachis associated with multiorgan infection due to Citrobacter koseri. Diagn Microbiol Infect Dis 2013; 77:370-2. [PMID: 24075632 DOI: 10.1016/j.diagmicrobio.2013.08.017] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2013] [Revised: 08/17/2013] [Accepted: 08/21/2013] [Indexed: 10/26/2022]
Abstract
Pneumorachis rarely occurs after spreading from a contiguous site of infection or after a traumatic event. We describe an adult patient who developed sepsis and a renal abscess due to Citrobacter koseri, and computed tomographic imaging identified gas within the entire spinal canal as well as an iliopsoas abscess. This patient recovered from pneumorachis caused by disseminated infection.

Abstract
INTRODUCTION Iliopsoas abscess (IPA) is a collection of pus in the iliopsoas compartment, which is considered rare in Japan. However, the number of patients with IPA has recently increased among the elderly or compromised hosts. SUBJECTS AND METHODS This retrospective study aims to examine the clinical pictures, pathological findings, and the prognostic factor of IPA. We analyzed all patients with IPA who were admitted to our hospital from April 2006 to July 2011. Patients' characteristics, treatment, clinical outcome, radiological findings, bacteria isolated, and comorbidities were evaluated. The comorbidities were evaluated by the Charlson comorbidity index (CCI). We compared the survival and non-survival groups to assess the prognostic factors of IPA. RESULTS A total of 33 patients were enrolled in this study, which included 14 males and 19 females. The mean age of the patients was 71.5 years (range 32-92 years). The most common underlying disease was spinal disease (16 of 33, 48.5%). Twenty-nine patients (87.9%) were cured and four patients (12.1%) died. While 12 patients (36.4%) were initially treated conservatively with antibiotics alone, percutaneous drainage was performed initially in 19 patients (57.6%). Two patients (6%) directly underwent exploratory surgery and open drainage. In terms of patients' characteristics, there were no significant differences in either group. The score of CCI in non-survivors was higher than that in survivors (1.38 vs. 5.5, P < 0.001). CONCLUSIONS The epidemiology of IPA is quite different from what it used to be. CCI appears to be useful in evaluating the patients' prognosis with IPA.
