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.

Intraabdommal abscess usually causes distress with fever, leukocytosis, pain and toxicity. Diagnosis of intraabdominal abscess is occasionally difficult and It has high morbidity. However radiologic method, such as ultrasonography, CT scan, or RI scan are helpful to early detection of intraabdominal abscess. Among these methods, ultrasonography is a non-invasive technique and performed without discomfort to patient. And also differential diagnosis between cystic and solid lesion is very easy and sequential ultrasonography in same patient is valuable for the evaluation of treatment effect. We analyzed the ultrasonic features of 48 cases with intra-abdominal abscesses and the results are as follows; 1. In total 48 cases, the intra-abdominal abscesses were 30 cases, the retroperitoneal abscesses, 5 cases, and the visceral abscesses, 13 cases. 2. The causes of the intra-abdominal abscesses were perforating appendicitis (25 cases), postoperative complications (5 cases), pyogenic and amebic hepatic abscesses (13 cases), and the others (5 cases). 3. Round or oval shaped lesions were 26 cases (54%), irregular shape, 18 cases (38%), and multiple abscess formation in 4 cases (8 %). 4. The size of the lesions were between 5 and 10cm in diameter in 54% of total 48 cases, and the most frequent feature of the echo-pattern of the lesions was cystic with or without internal echogenicity (69%).

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.

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.

A 68-year-old man presented with a bed sore with pus discharge on lower back. Radiographs showed extensive destruction of the L4 vertebral body. Magnetic resonance imaging (MRI) showed fluid collection with an enhanced wall at the defect of the L4 vertebral body extending into both psoas muscles. The primary diagnosis was neuropathic spondylopathy, but infective spondylitis was not ruled out. Initially, he was treated with antibiotics for two weeks. A follow-up MRI showed no improvement of the abscess, so surgical exploration was done. Charcot spinal arthropathy resulted in extensive vertebral body destruction that may be similar to infectious spondylitis, particularly in the case with fluid accumulation due to rupture of dura.
