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.

OBJECTIVE: Infectious spondylitis is mostly managed by appropriate antibiotic treatment options, and some patients may require surgical interventions. However, surgical interventions that use spinal instrumentation to correct the mechanical instability may be associated with the risk of an increase in the recurrence rate. In this study, we investigated whether spinal instrumentation effects on recurrence of infectious spondylitis. METHODS: The study was conducted as a retrospective study by dividing the subjects into the noninstrumentation surgery and instrumentation surgery groups among a total of 95 patients who had received surgical interventions in infectious spondylitis from 2009 to 2014. The study investigated patient variables such as underlying illness, presumed source of infection, clinical data, laboratory and radiological data, and ultimate outcome, and compared them between the 2 groups. RESULTS: In the 95 patients, instrumentation was not used in 21 patients but it was used in 74 patients. When the disease involved ≥3 vertebral bodies, lumbosacral level and epidural part, noninstrumentation surgery was mainly conducted, but when the disease involved the thoracic level and psoas muscle part, instrumentation surgery was mainly conducted. However, there were no differences between the 2 groups in terms of the recurrence rate and the incidence of primary failure. CONCLUSION: The use of instrumentation in treating infectious spondylitis was determined by the level of involvement and part of the infection, but the use of instrumentation did not cause any increases in the recurrence rate and the incidence of primary failure.

We expierienced five cases of bilateral inferior vena cava for recent one year. We evaluated the CT findings of the cases and of dilated veins located in the left retroperitoneum (seven left gonadal, seven inferior mesenteric, and two left ascending lumber veins)in the viewpoints of the size, location and relation with the surrounding structures. Bilateral inferior vena cava (IVC) may be asymmetric and the left IYC may be smaller than other retroperitoneal veins with a round contour. The left lYC was located anterior to the spinal body and corresponded with contralateral vena cava in the anteroposterior plane. The gonadal vein was located anterior or anterolateral side of the psoas and always crossed the ureter. Most of the inferior mesenteric vein showed similar location to the opposite site of the vena cava in the anterolateral side of the psoas muscle, medial to the left ureter without crossing. The left ascending lumbar vein was similarly located to the left vena cava but dilated in a short segment. It is required to trace the vessel upward and downward and observe its continuity for correct differentiation. If it is impossible, some differential points suggested in the results of our study will be helpful for distinguishing them.

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.

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.
