We report a case of primary psoas abscess which is a relatively rare condition. The etiology of this disease remain uncertain, but the hematogeneous seeding have been proposed as initiating factors. The clinical presentation and review of literature are discussed.
Psoas Abscess*

Psoas abscess is a rare and high mortality disease if there is no appropriate treatment. The surgical approach of psoas abscess is very difficult because psoas muscle is anatomically located within retroperitoneum. Recently, computed tomography guided percutaneous catheter drainage with proper antibiotic therapy has shown good results. If this therapy fails to resolve the psoas abscess, surgical treatment may be necessary. We experienced two cases of psoas abscess resolved by surgical drainage using laparoscopy. We report two successful results with relevant literatures.

One fourth of cases of non-Hodgkin lymphoma were reported as extranodal type and skeletal muscle involvement rarely seen as a primary event and local dissemination. The psoas involved lesion with spine mimicking pain is caused mainly by infection rather than non-infected conditions such as tumor. We report on a rare case of non-Hodgkin lymphoma occurring in psoas muscle, which required differentiation from a psoas abscess.

Conventional radiologic methods had given the limited informations about itraabdominal abscesses. Today,however, CT and ultrasongraphy provide detailed anatomic location, number and dimension of intraabdominal abscessand also permit percutaneous placement of catheter large enough to effect drainage. Percutaneous catheter drainageof intraabdominal abscess now offers an alternative to surgery. This simple method of mechanical drainage, whenemployed with systemic antibiotics, can be successful in treating the majority of intraabdominal abscesses.Authors analysed 24 cases of percutaneous abdominal abscess drainage performed at chonnam Natinal UniverstiyHospital from May 1985 to June 1986. The results were as follows: 1. The sites of abscesses; liver in 14cases(58.3%), psoas muscle in 3 cases(12.5%), subphrenic space in 3 cases (12.5%), pelvic cavity in 2 cases(8.3%),perirenal space in 2 cases(8.3%). 2. Complications during or after procedures were minor in the majority of cases.3. Average duration of drainage was as follows: 7.8days in liver abscess, 15.3 days in psoas abscess, 6 days inpelvic abscess, 7 days in subphrenic abscess.

Acupuncture has been widely used in alternative medicine for pain relief but may have many complications due to lack of appropriate cares. Pharmacopuncture is a sort of acupuncture that injects a herbal ingredient through a thin tube for the purpose of combining the effects of the herb and acupuncture and it has many pitfalls. The agents used in pharmacopuncture are not refined for a desired effect and not produced by sterile standard processes under strict medical surveillance. We report a case of a 44-yr-old male patient who had multiple abscesses in the psoas region with fever, right low back and hip pain that began after the pharmacopuncture treatment. This case shows that although pharmacopuncture has been practiced widely, it is important that the appropriate aseptic technique should be used to prevent severe infections and other complications.

Tuberculous Iliopsoas muscle abscess is a rare manifestation in patient with extrapulmonary tuberculosis and hardly observed in developed country. Paradoxical response to anti-tuberculous medication could make difficult therapeutic decision to clinicians. The authors report a case of tuberculous iliopsoas muscle abscess with multiple intraabdominal and thoracic abscesses in 9 year-old-boy who presented paradoxical response to anti-tuberculous treatment.

The authors present a rare case of tuberculous spondylitis and a large abscess in the left psoas muscle that occurred after spinal surgery for an acute traumatic burst fracture of the L2 vertebral body. We retrospectively reviewed the patient's first magnetic resonance imaging (MRI) we found that some unusual findings, indicative of psoas abscess had been overlooked. As a result, diagnosis and treatment of tuberculous psoas abscess and spondylitis were considerably delayed. Despite the critical condition of patients in a similar emergency, surgeons should always pay close attention to the radiological findings and clinical symptoms of the patient before considering a surgical intervention or biopsy.

A retrospective analysis of the ultrasonographic findings of 9 cases of tuberculous abscess, 5 cases of pyogenic abscess and 2 cases of hematoma of psoas and adjacent muscles was made. Fluid collection with or without internal echoes was seen in 12 cases out of total 16 cases. Other findings were 2 cases of only muscle swelling, 1 case of highly echogenic mass.like appearance and 1 case of fluid collection with septae. Ultrasonography is considered an accurate method in identifying early pathologic changes of the psoas muscle and determining its extent. and in differentiating tumor from fluid collection of the psoas muscle. Authors dare to say that ultrasound examination is a procedure of choice in the diagnosis of psoas abscess and hematoma.

Primary pyogenic psoas abscess is rare lesion, and often is not suspected. Reasons for delayed diagnosis are unfamility with the lesion and the fact that symptoms often resemble those of primary disease of the hip. We present a case of primary pyogenic psoas abscess in child, which was diagnosed by MRI, and completely recovered after surgical treatment.

Nucleoplasty is a newly developed minimal invasive spinal surgery using a coblation technique. The complications of this new spinal surgery are trauma to retroperitoneal organs involving the kidney, discitis, menigitis, and epidural abscess. Recently, postoperative psoas abscess and discitis appears to have increased in frequency, in part because procedures performed on the spine have been more frequent and improvements in diagnostic capabilities have been made. Antibiotic therapy, abscess drainage, or a surgical procedure is required to treat discitis and psoas abscess. We encountered one case of postoperative psoas abscess and discitis after a nucleoplasty that had not responded to antibiotics but which responded successfully to treatment by spinal surgery.
