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.

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.

OBJECTIVE: Many studies have investigated paraspinal muscle changes after posterior lumbar surgery, including lumbar fusion. However, no study has been performed to investigate back muscle changes after pedicle based dynamic stabilization in patients with degenerative lumbar spinal diseases. In this study, the authors compared back muscle cross sectional area (MCSA) changes after non-fusion pedicle based dynamic stabilization. METHODS: Thirty-two consecutive patients who underwent non-fusion pedicle based dynamic stabilization (PDS) at the L4-L5 level between February 2005 and January 2008 were included in this retrospective study. In addition, 11 patients who underwent traditional lumbar fusion (LF) during the same period were enrolled for comparative purposes. Preoperative and postoperative MCSAs of the paraspinal (multifidus+longissimus), psoas, and multifidus muscles were measured using computed tomographic axial sections taken at the L4 lower vertebral body level, which best visualize the paraspinal and psoas muscles. Measurements were made preoperatively and at more than 6 months after surgery. RESULTS: Overall, back muscles showed decreases in MCSAs in the PDS and LF groups, and the multifidus was most affected in both groups, but more so in the LF group. The PDS group showed better back muscle preservation than the LF group for all measured muscles. The multifidus MCSA was significantly more preserved when the PDS-paraspinal-Wiltse approach was used. CONCLUSION: Pedicle based dynamic stabilization shows better preservation of paraspinal muscles than posterior lumbar fusion. Furthermore, the minimally invasive paraspinal Wiltse approach was found to preserve multifidus muscles better than the conventional posterior midline approach in PDS group.

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.

Three patients have successfully undergone ureteroneoystostomy with submucosal tunneling as an antirefluxing measure using vesico-psoas hitch procedure for extensive postoperative stricture of the lower ureter. Postoperatively, none of the patients has developed ureterovesical stenosis, and functional capacity of the bladder has been well preserved despite of extensive mobilization. In one patient reflux has occurred through the ureteral orifice of the opposite side. Since the technique of vesico-psoas hitch procedure is simply to mobilize the bladder and to fix its posterolateral corner to the psoas muscle, we believe that it provides a safer alternative to more complicated and potentially dangerous procedures.

The lumbar sympathetic ganglion block (LSGB) is widely used for diagnosing and treating sympathetically maintained pain disorders. The LSGB has been conventionally carried out under fluoroscopy or computed tomography guidance. However, as ultrasound technology improved, ultrasound-guided interventions have been expanding their territory to deeper structures. Ultrasound guidance provides many benefits including protecting vascular injection, shortening procedure time in some cases, and reducing the emission of radiation. In this report, we describe a successful case of a US-guided LSGB without major complications. We expect that US-guided LSGBs can be implemented and furnished in the daily outpatient clinical setting by highly trained pain physicians.

Sciatic nerve palsy is the most common nerve injury associated with acetabular fracture and dislocation, but femoral nerve injury is known to be very rare because of relative protected position of nerve between the iliacus and psoas muscle, and as far as we know only one report was noted in English about combined femoral and sciatic nerve injury associated with acetabular fracture and dislocation, so we hereby report a case of combined femoral and sciatic nerve palsy associated with acetabular fracture and dislocation.

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.
