Polybacterial Iliopsoas Muscle Abscess as an Indication for Early Diagnosis of Crohn's Disease.

BACKGROUND Crohn disease (CD) is a chronic, relapsing inflammatory bowel disease characterized by penetrations or fistulae in the gastrointestinal tract and abscesses in the surrounding tissues. Diagnosis of CD is difficult with an iliopsoas muscle abscess (IMA) as an initial presentation. CASE REPORT A 22-year-old Japanese man had right hip pain 17 days prior to admission. Because of worsening pain, he was admitted to our hospital. Physical examination revealed limitation of his right hip motion and a positive right psoas sign. Abdominal contrast-enhanced computed tomography (CT) revealed a large right IMA. Continuous drainage, which revealed polymicrobial pus, with intravenous administration of antibiotics dramatically decreased the size of the IMA. The drainage tube was removed on hospitalization day 9 because barium enema and contrast radiography of the abscess through the drainage tube showed no fistula. However, on day 19 of hospitalization, the IMA was redetected by abdominal CT. Continuous abscess drainage was resumed, and the third contrast radiograph of the abscess revealed contrast medium flow into the small intestine. Colonoscopy detected stenoses and circumferential ulceration of the terminal ileum. Histopathological examination of the ileum biopsy showed histocyte aggregation with lymphocyte or plasmacyte infiltration of the lamina propria, compatible with a CD diagnosis. Laparoscopic ileocecal resection was performed on day 64 of hospitalization. CONCLUSIONS Penetration of the intestinal tract caused by CD should be suspected in a patient with a polymicrobial IMA. It is essential to identify the fistula and subsequently perform surgical resection of the affected intestinal area.

An 81-year-old male with iliopsoas abscess by Streptococcus sanguis.

Iliopsoas muscle abscess is an uncommon condition, which has been growing in incidence. We describe a primary iliopsoas abscess by Streptococcus sanguis affecting an 81-year-old man cured by antibiotic therapy and aspiration procedure. The objective is to enhance the suspicion index about the iliopsoas abscess that may be mistaken for other causes of acute abdomen. The important diagnostic role of abdominal imaging studies is also emphasised.

Successful treatment of chronic intractable itching using oral pregabalin in a patient with diabetes and systemic prurigo nodularis: a case report of an iliopsoas muscle abscess.

A 73-year-old Japanese man developed chronic intractable itching due to prurigo nodularis. High-dose glucocorticoid ointment failed, and the treatment resulted in poor glycemic control. Repeated scratching caused hematogenous bacterial dissemination via cutaneous injuries, resulting in the formation of iliopsoas and spinal epidural abscesses that required long-term antibiotic treatment. Pregabalin was administered to treat the pruritus, and a considerable improvement was observed. A reduction in the dose and intensity of the topical corticosteroids improved the patient's glycemic control, resulting in the complete resolution of the abscesses. Pregabalin significantly improved the patient's pruritus and decreased the risk of infection.

[Necrotizing fasciitis after "banal" back pain. An unusual course of a retrocoecal appendicitis and its sequellae]. / "Banale" Rückenschmerzen als erstes Symptom einer nekrotisierenden Fasziitis : Ungewöhnlich verlaufende retrozökale Appendizitis und ihre Folgen.

Necrotizing fasciitis is a life-threatening disease which can only be successfully treated by an interdisciplinary team. An immediate and radical debridement with opening of all compartments and debridement of the affected fascia is the basis for a successful therapy. We report about the treatment of a 21-year-old man who was taken to hospital due to "banal" back pain which was caused by a perforated appendicitis. In only 2 days necrotizing fasciitis developed which spread out over the complete right leg.

Polyarticular septic arthritis with bilateral psoas abscesses following acupuncture.

We report a case of polyarticular septic arthritis with bilateral psoas abscesses. A 50-year-old woman was admitted with fever, multiple joint swelling and pain. She had a clinical history of acupuncture therapy for treatment of her chronic lower back pain two days before the appearance of her symptoms. Methicillin-sensitive Staphylococcus aureus was isolated from blood culture, knee joint fluids and psoas abscess. After a long course of antibiotics for 70 days together with drainage of the abscess, the condition completely resolved. The acupuncture is the probable cause of the infection, and this case report reveals the importance of asking about a clinical history of acupuncture treatment and of making repeated bacterial examinations in undiagnosed polyarthritis patients.

Abscesso do músculo psoas em paciente submetida à analgesia por via peridural: relato de caso / Psoas muscle abscess after epidural analgesia: case report

JUSTIFICATIVA E OBJETIVOS: O abscesso do músculo psoas é uma complicação rara da analgesia peridural. O manuseio adequado dessa intercorrência é fundamental para uma boa resolução do quadro clínico. O objetivo deste relato foi discutir o diagnóstico e o tratamento do abscesso do músculo psoas. RELATO DO CASO: Paciente do sexo feminino, 65 anos, com dor neuropática nos membros inferiores de difícil controle com medicamentos por via sistêmica. Optou-se pela administração de opióide e anestésico local por via peridural como alternativa analgésica. Vinte dias após o uso contínuo da via peridural, a paciente começou a apresentar dor na região lombar, cefaléia e febre. A tomografia computadorizada da pelve revelou abscesso do músculo psoas, sendo indicada drenagem fechada e antibioticoterapia. CONCLUSÕES: A supervisão minuciosa do paciente é necessária e deve ser contínua quando um cateter peridural for colocado. Essa vigilância deve ser mantida após a sua retirada.

BACKGROUND AND OBJECTIVES: Psoas muscle abscess is a rare complication of epidural analgesia. The adequate approach to this complication is fundamental for a good resolution. The objective of this report was to discuss the diagnosis and treatment of psoas muscle abscess. CASE REPORT: A female patient, 65 years old, with neuropathic pain in the lower limbs, difficult to control with systemic drugs. The patient was treated with epidural opioid and local anesthetic as an alternate treatment. Twenty days after the continuous epidural administration, the patient complained of lumbar pain, headache, and fever. A CT scan of the pelvis showed an abscess of the psoas muscle, thus, closed drainage and antibiotics were indicated. CONCLUSIONS: An adequate, continuous supervision of the patient is necessary when an epidural catheter is placed, and it should continue after its removal.

Paraplegia caused by spinal infection after acupuncture.

STUDY DESIGN: Case report of a 64-year-old man with psoas abscesses, epidural abscess and spondylitis after acupuncture. OBJECTIVE: To report a case of paraplegia caused by spinal infection after acupuncture. SETTING: Seoul, Korea. CASE REPORT: A 64-year-old man came to an emergency room because of severe back pain. At 3 days prior to visit, the patient received acupuncture therapy to the low back with a needle about 10 cm in length because of back pain. Pain was aggravated gradually for 3 days. Escherichia coli sepsis developed with altered mentality during admission. At hospital day 9, he regained his consciousness and was found to have paraplegia. Abdominal computerized tomography (CT) and lumbar spine magnetic resonance imaging (MRI) revealed abscesses of bilateral psoas muscles and spondylitis with epidural abscess. After conservative management with intravenous administration of antibiotics, infection was controlled but the patient remained paraplegic (ASIA scale C L1 level) without neurological recovery. CONCLUSION: Paraplegia might result from complications of an acupuncture therapy.

Psoas abscess and cellulitis of the right gluteal region resulting from carcinoma of the cecum.

Although retroperitoneal or psoas abscess is an unusual clinical problem, the insidious and occult characteristics of this abscess sometimes cause diagnostic delays, resulting in considerably high morbidity and mortality. In particular, psoas abscess caused by perforated colon carcinoma is uncommon. We report a case of psoas abscess caused by a carcinoma of the cecum. A 72-year-old Japanese woman was admitted to our hospital, with pain in the right groin and buttock. The pain had appeared 6 months before admission, and the symptoms had then been relieved by oral antibiotics. On March 25, 1999, inflammatory signs in the right buttock indicated localized cellulitis, and incision and drainage was performed at a local hospital. The patient was referred to our hospital on the same day. On admission to our hospital, computed tomography (CT) scan revealed a thick right-sided colonic wall and enlargement of the right ileopsoas muscle. Barium enema and colonofiberscopy revealed an ulcerated tumor occupying the entire circumference of the cecum. A retroperitoneal abscess and fistula had been formed by the retroperitoneal perforation of cecum carcinoma: surgical resection was performed after remission of the local inflammatory signs. Operative findings indicated that the cancerous lesion and its surrounding tissues were firmly attached to the right iliopsoas and major psoas muscle, and en-bloc resection, including adjacent muscular tissue, was performed. The fact that carcinoma of the colon could be a cause of psoas abscess and cellulitis in the gluteal region should be considered when an unexplained psoas abscess is diagnosed.

Propionibacterium avidum sacroiliitis and osteomyelitis.

The anaerobic Gram-positive bacterium Propionibacterium avidum is a common inhabitant of the skin with low pathogenicity. We report a case of P. avidum sacroilitis, psoas abscess and osteomyelitis in a 67-year-old male who had recently undergone surgical repair of an inguinal hernia. The organism was recovered from blood cultures, a bone biopsy specimen and specimens from the abscess. The spectrum of bone and joint infections caused by Propionibacterium is discussed. Infection by Propionibacterium spp. should be considered in patients with bone and joint infections.
