1/266. Obturator internus muscle abscess in children: report of seven cases and review.Obturator internus muscle (OIM) abscess is an uncommon entity often mistaken for septic arthritis of the hip. We describe seven children with OIM abscess and review seven previously reported cases. The most common presenting symptoms were hip or thigh pain (14 patients), fever (13), and limp (13). The hip was flexed, abducted, and externally rotated in 11 patients. magnetic resonance imaging and computed tomography (CT) were diagnostic for OIM abscess in the 14 patients. Associated abscesses were located in the obturator externus muscle (5 patients), psoas muscle (2), and iliac muscle (1). The etiologic agents were Staphylococcus aureus (8 patients), streptococcus pyogenes (2), neisseria gonorrhoeae (2), and enterococcus faecalis (1). Three patients underwent CT-guided percutaneous drainage, and three had surgical drainage. Three patients had ischial osteomyelitis in addition to OIM abscess. The 11 children with uncomplicated OIM abscess were treated for a median of 28 days. All patients had an uneventful recovery.- - - - - - - - - - ranking = 1keywords = muscle (Clic here for more details about this article) |
2/266. Pubic pain in athletes: a case due to an abscess in the obturator muscle.Pubic pain is a common symptom in soccer players. Its cause can be difficult to determine. We report a case in a 19-year-old soccer player who had an abscess in the obturator internus muscle. We are aware of only one similar report in the literature. Painful limitation of internal rotation of the hip and evidence of infection suggested the diagnosis, which was confirmed by magnetic resonance imaging. In a soccer player, a fever and groin pain do not always indicate osteitis pubis. Limitation of internal rotation of the hip should suggest a lesion in the obturator internus muscle.- - - - - - - - - - ranking = 0.75keywords = muscle (Clic here for more details about this article) |
3/266. Spinal epidural abscess associated with epidural catheterization: report of a case and a review of the literature.We describe a 53-year-old man who developed a catheter-related epidural abscess 8 days after left upper lobectomy for lung cancer. methicillin-resistant staphylococcus aureus (MRSA) was detected in a culture of the epidural pus. magnetic resonance imaging was essential for the diagnosis of epidural abscess and for determining the extent of spread. The patient was treated by laminectomy and administration of appropriate antibiotics, with almost complete recovery, except for urinary retention. A literature search yielded 29 additional cases of catheter-related epidural abscess. The median duration of catheterization was 4 days and the median time to onset of the clinical symptoms after catheter placement was 8 days. Eleven of the 30 patients had some underlying disorders, including malignancy or herpes zoster, or were receiving steroids. Nine of the 10 patients with thoracic epidural abscess had persistent neurological deficits, whereas 12 of the 15 patients with lumbar epidural abscess showed a full recovery after treatment. Surgical decompression was not required in six patients without significant neurological deficits, who recovered following antibiotic treatment (four patients) or percutaneous drainage (two patients). Thoracic catheters are associated with a disproportionately high incidence of epidural abscess and persistent neurological sequelae following treatment.- - - - - - - - - - ranking = 0.028955241049723keywords = cancer (Clic here for more details about this article) |
4/266. Intrathoracic suture abscess after lobectomy for early lung cancer.Intrathoracic suture abscess may occur around sutures on the pleura or in the lung parenchyma, although it is rare to encounter such cases clinically. We report on a 68-year-old woman with an intrathoracic (extrapulmonary) suture abscess, which was discovered on a chest x-ray film one year after right-middle lobectomy for early lung cancer. The abscess was removed surgically, and the postoperative course was uneventful. Pathological examination showed that it was caused by braided polyester sutures.- - - - - - - - - - ranking = 0.14477620524861keywords = cancer (Clic here for more details about this article) |
5/266. Parietal mesh abscess as an original presentation of cancer of the caecum.We report a case of cancer of the caecum in a 71-year-old male who presented with parietal mesh abscess. Two years before, he was treated for a right inguinal hernia by insertion of a Dacron mesh. CT scan then colonoscopy determined the existence of a voluminous caecal tumor perforated in the abdominal wall with an important abscess around the mesh. Right colectomy and parietal muscles excision were performed completed with postoperative radiochemotherapy. At 2 years, there is no evidence of recurrence. Atypical features with a hernia mesh repair associated with a sudden change in the patient's condition should alert the clinician to the possibility of a further subjacent pathological process.- - - - - - - - - - ranking = 0.26977620524861keywords = muscle, cancer (Clic here for more details about this article) |
6/266. sinusitis with contiguous abscess involvement of the clivus and petrous apices. Case report.A wide spectrum of diseases may involve the clivus, such as primary neoplasms, metastatic disease, and inflammatory, vascular, hematopoietic, and infectious processes. Of these, osteomyelitis of the skull base and/or clival-petrous abscess are unusual, but may occur as a result of contiguous spread from the paranasal sinuses, namely, the posterior ethmoid and sphenoid, as was demonstrated by this patient. In this case report we discuss the pertinent anatomy, imaging studies, pathogenesis, and medical and surgical management of this case.- - - - - - - - - - ranking = 0.0027238629448026keywords = neoplasm (Clic here for more details about this article) |
7/266. MRI of tuberculous pyomyositis.PURPOSE: The purpose of this article is to describe the findings of MRI in tuberculous pyomyositis (PM). METHOD: The MR images of four proven cases of tuberculous PM were retrospectively reviewed and analyzed with clinical and laboratory findings. The location, signal intensity on T1- and T2-weighted spin echo images, presence of abscess, signal intensity of peripheral rim, patterns of contrast enhancement, and associated findings were evaluated. RESULTS: On MR images, all cases demonstrated low signal intensity on T1-weighted images and high signal intensity on T2-weighted images in a single muscle. Abscess was seen in all cases. Peripheral rim showed subtle hyperintensity on T1-weighted images and hypointensity on T2-weighted images. After gadolinium infusion, peripheral rim enhancement was observed in all cases. cellulitis was associated in one case. The patients clinically presented with a palpable mass of long duration. CONCLUSION: Tuberculous PM shows characteristic findings of a well demarcated abscess with rim enhancement at MRI and can be distinguished from other soft tissue masses.- - - - - - - - - - ranking = 0.125keywords = muscle (Clic here for more details about this article) |
8/266. nocardia asteroides pneumonia, subcutaneous abscess and meningitis in a patient with advanced malignant lymphoma: successful treatment based on in vitro antimicrobial susceptibility.nocardia asteroides pneumonia, subcutaneous abscess and meningitis without brain abscesses developed in a patient with advanced non-Hodgkin's lymphoma, who had received corticosteroid therapy and cancer chemotherapy for a long time. At the time of nocardial pneumonia, profound lymphocytopenia and hypogammaglobulinemia was seen. The severely immunosuppressed condition most likely accounted for the uncommon infection, nocardiosis. The organism isolated from the sputum, subcutaneous abscess and cerebrospinal fluid was strongly resistant to cotrimoxazole, which is the recommended standard treatment, but it was susceptible to imipenem (IPM) and erythromycin (EM) in an in vitro antimicrobial susceptibility study. The patient's nocardiosis responded well to chemotherapy including IPM and EM.- - - - - - - - - - ranking = 0.028955241049723keywords = cancer (Clic here for more details about this article) |
9/266. Primary iliac muscle abscess due to Staphylococcus aureus.A 55-year-old man presented with a 3-day history of lower back pain and right thigh pain. A diagnosis of discogenic pain had been made at two other hospitals. He had been admitted to a medical center for acute hepatitis 5 months prior to this admission. Large doses of parenteral hydrocortisone were used for 13 days to treat acute hepatitis. At the present admission, he was unable to stand and refused to move his right leg. There was mild tenderness in the right lower abdomen on deep palpation. Passive flexion and rotation of the right hip produced mild pain, while passive extension of the right hip produced severe pain and resistance. The Patrick test was positive and the psoas sign was present on the right side. The erythrocyte sedimentation rate (ESR) was 66/hr. The c-reactive protein (CRP) level was 0.161 g/L. Abdominal sonography showed a lobulated mass in the right iliac fossa. magnetic resonance imaging showed severe swelling of the right iliac muscle with a central heterogeneous mass. debridement, drainage of the abscess, and application of a septopal chain were performed via an anterior retroperitoneal approach, and parenteral cephazolin and gentamicin were administered. A culture of the abscess grew Staphylococcus aureus. The ESR and CRP concentrations decreased to within the normal ranges 3 weeks later. awareness of this disease entity, careful physical examination, and appropriate imaging studies such as ultrasonography and magnetic resonance imaging are key to making a correct diagnosis.- - - - - - - - - - ranking = 0.625keywords = muscle (Clic here for more details about this article) |
10/266. esophageal perforation and mediastinal abscess following placement of a covered self-expanding metallic stent and radiation therapy in a cancer patient.patients with advanced esophageal cancer may require intubation with a stent to relieve debilitating dysphagia. However, if these patients also undergo radiation therapy, they may incur esophageal injury, thus increasing the risk of perforation after placement of the stent. Herein we report the case of a 71-year-old man who received such combination therapy and died of severe sepsis 65 days after the stent was inserted. An autopsy revealed that the stent had perforated into the mediastinal pleura and that an abscess had developed around the perforation. We conclude that caution should be taken before combining radiation therapy with the use of a stent.- - - - - - - - - - ranking = 0.14477620524861keywords = cancer (Clic here for more details about this article) |
