Although surgical drainage has been performed in most reported cases of psoas abscess, ultrasonographically guided percutaneous drainage could be effective treatment for psoas abscess. However, utility of percutaneous drainge under ultrasound is less well established. We present a patient in whom fungal psoas abscess was managed by ultrasonographically guided percutaneous aspiration with literature review. Drainage was done by needle aspiration under ultrasound guidance and there was no procedural complication. After aspiration, Candida Albicans was found as a causing organism responsible for abscess and abscess could be successfully treated by repeated aspiration and appropriate antifungal therapy.

A healthy, 14-year-old boy presented with right hip pain and consequent fever after falling out of bed while sleeping. The patient could not walk and complained of severe pain with active and passive motion, which consisted mainly in extension and internal rotation of the right hip. Laboratory analysis of the peripheral blood identified leukocytosis and increased levels of acute phase reactants. Magnetic resonance imaging of the hip, which was performed with the expectation of right hip pathology, revealed cellulitis and abscess in the right psoas muscle and associated inflammatory changes in the adjacent presacral fat plane but showed no abnormal lesions in the adjacent pelvic bone and spine. Staphylococcus hominis was cultured from the blood. With empirical antibiotic therapy, the patient recovered fully. We report a case of primary psoas abscess confused with hip pathology in an immunocompetent child without underlying disease.

Objectives : This study was performed to examine the hypothesis that the structural imbalance affect cardiac function and autonomic reflex system and to investigate the possibility of the chiropractic care for cardiovascular system. Methods : 78 of Dong-Guk University students with structural imbalance were recruited for the investigation from March to June 2007. Heart rate variability, Buss and Durkee Hostility inventory(BDHI) and physical examinations to evaluate psoas muscle contracture were performed. Results : Left psoas muscle contracture was associated with decrease of LF/HF ratio(p=0.048). Conclusion : Left side contracture of psoas muscle showed a tendency to decrease sympathetic activity.

The trigger point injection technique is widely used in pain clinics for the treatment of acute and chronic pain. Yet it has a variety of complications such asvasovagal syncope, total spinal anesthesia, paralysis, root block, pneumothorax, needle breakage, skin infection, and hematoma formation. Among them, the simultaneous occurrence of psoas and epidural abscesses is extremely rare. We report here on a patient who was diagnosed with epidural and psoas abscesses after paravertebral trigger point injection.

A tuberculous psoas abscess is a frequently described complication of tuberculous spondylitis. Although rare, a tuberculous psoas abscess can develop without any demonstrable spinal involvement. In patients with no evidence of sponylitis, the abscess may result from direct spread from the involved lymph node or via a hematogeous route. The treatment of a psoas abscess is either drug therapy or surgical intervention in conjunction with drug therapy. Image-guided percutaneous drainage in conjunction with drug therapy is also a safe and effective treatment for a tuberculous psoas abscess. We report an unusual case of bilateral tuberculous psoas abscesses without any concomitant spinal involvement. The tuberculous psoas abscess may have formed by fistulization between the necrotic lymph node and psoas sheath. The diagnosis was confirmed by computed tomography and a histology examination of the biopsy sample. The patient improved after administering anti-tuberculous agents for 2 years along with surgical and percutaneous drainage of the abscess.

Purpose: The purpose of this experimental study have been testifying about reactive muscle control regarding sternocleidomastoid and psoas. Low back pain patient do not sit-up exercise without abnormality of trunk flexor. The reason of problem is unbalance sternocleidomastoid and psoas. According to George J, Goodheart who have been developing Applied Kinesiology (A. K.) since reactive muscle recognized gait testing in 1964. Materials and Methods: From September, 2004 to February, 2005, I have controled sternocleidomastoid and psoas. It is applied to the patients who are unable sit up exercise at Yang-Dong local clinic, Yang-Pyung county, Kyung-Gi Do province in Korea. 24 Patients divided 2 groups. A group is applied general physical therapy. Also B group is added reactive muscle control from M.E.M.P.T.(Korean society of muscle and energy monitoring physical therapy) Results : The results of this study follow. 1. Possible sit up group 8 persons of the second group. 2. Not possible sit up group the others. Conclusion: The study present that reactive muscle control sternocliedomastoid and psoas is useful in patient with low back pain is difficult to sit up.

The vast majority of schwannomas occur on cranial nerves, and rarely in the retroperitoneum. Solitary schwannoma in the psoas muscle is extremely rare. The authors present a case of retroperitoneal neoplasm in the psoas muscle identified as schwannoma which is not associated with von Recklinghausen's disease. A 68 years old female patient was admitted because of low back pain and weakness at the left leg. CT and MRI revealed a large cystic mass with well-defined margin and multiple internal septation within the left psoas muscle. The tumor was totally extirpated and histologically confirmed as a schwannoma.

Objectives : This study was designed to evaluate the correlation of the cross-sectional areas(CSA) of paraspinalis(iliocostalis lumborum, multifidus, longissimus thoracis parts lumborum) and psoas muscle and sex, age, change of the VAS(visual analogue scale) and past history of chronic low back pain in patients suffering from HIVD(herniation of intervertebral disc). Methods : Medical records of 140 subjects with HIVD were retrospectively reviewed. The MRI(magnetic resonance imaging) findings on the patients were scanned and analyzed by PiView program to find the paraspinal and psoas muscle CSA and were evaluated by the correlation of sex, age, change of the VAS, and past history of chronic low back pain. Results : There was significant difference between groups in male and female, young-adults age and middle age, middle age and old age, young-adults age and old age. But the correlation of the paraspinal and psoas muscle CSA and past history of chronic low back pain were partially significant. On the other hand, the correlation of the paraspinal and psoas muscle CSA and change of the VAS were not significant. Conclusions : These results suggest that the cross-sectional areas(CSA) of paraspinalis and psoas muscle have relevance to sex and age.

Renal and perinephric abscesses are a rare but potentially fatal complication of urinary tract infection (UTI). Diagnosing renal and perinephric abscesses has been known to be difficult. These abscesses may occur when the appropriate antibiotic treatment for a UTI is delayed, or in cases with a congenital malformation of the urinary system, especially in children. In the present report, we describe 2 cases of renal abscesses with extra-capsular invasion in children with febrile UTI. A 4-month-old male infant with vesicoureteral reflux developed a renal abscess that infiltrated the perinephric area and the left psoas muscle, despite early antibiotic treatment. A 9-year-old boy with prolonged fever also showed a multi-loculated renal abscess that infiltrated the spleen and diaphragm. Both patients were successfully treated with appropriate antibiotics and percutaneous drainage.
