Ultrasonography (US) plays a major diagnostic role in the pre- and post-transplant evaluation of recipient and donor. In most cases, US remains the only necessary imaging modality. After pediatric kidney transplantation, US can ensure immediate bedside diagnosis of vessel patency and possible postoperative non-vascular complications. Read More

In this paper, we describe the pattern of an idiopathic corpus cavernosum (CC) abscess using contrast-enhanced ultrasound (CEUS) and compare this to the lesion characterization achieved using preliminary baseline ultrasound/color doppler (ECD). In a 43-year-old man, who arrived at our emergency department for a penile swelling and hematopyuria, ECD examination showed equivocal mucosal and subcutaneous tissue swelling, an inhomogeneous hypoechoic area in the left CC, and a suspected millimetric interruption of the albuginea. CEUS showed multiple avascular areas wrapped in a hyperperfused rim representing abscesses and a not-perfused balanopreputial-oriented fistula. Read More

Background: Pseudoaneurysms of the foot are rare and can occur from a range of etiologies, including laceration from a foreign body. The majority of reported cases have been diagnosed by computed tomography, magnetic resonance imaging, or angiography. These tests require intravenous access and contrast, confer radiation, take time to perform and interpret, are expensive, and are not always readily available in the acute setting. Read More

Study Objective: We examine the utility of emergency department (ED) ultrasonography in treatment of skin and soft tissue infections.

Methods: We enrolled ED patients with skin and soft tissue infections and surveyed clinicians in regard to their pre-ultrasonography certainty about the presence or absence of an abscess, their planned management, post-ultrasonography findings, and actual management. We determined sensitivity and specificity of ultrasonography and clinical evaluation, and assessed appropriateness of management changes based on initial clinical assessment and outcomes through 1-week follow-up.

Department of Pediatrics, Awaji Medical Center, Sumoto City, Hyogo Prefecture, Japan.

Background: Although fractures of the sternum are rare in young children, owing to the compliance of the chest wall, these fractures are still possible and require thorough examination. We present a case that emphasizes the usefulness of point-of-care ultrasound in the diagnosis of a pediatric sternal fracture complicated by a subcutaneous abscess.

Case Report: A 5-year-old boy presented with tenderness of the sternum, with diffuse swelling extending bilaterally to the anterior chest wall. Read More

In our study, we sought to report the management, clinical outcomes, and follow-up rates of patients who presented for evaluation of breast abscess in the Emergency Department (ED) after hours. A retrospective search of ultrasound reports at our institution identified all patients from January 1, 2009 to June 30, 2013 who were scanned in the ED after hours to evaluate for breast abscess. Patient demographics, clinical information, imaging findings, follow-up rates, and outcomes were reviewed. Read More

Department of Emergency Medicine, Tufts University School of Medicine, Baystate Medical Center, Springfield, Massachusetts.

Background: The red, swollen, infected hand can be a diagnostically challenging presentation in the emergency department (ED). Hand infections are a relatively uncommon ED complaint, and diagnoses may range from simple cellulitis to deep space abscess, and even to suppurative flexor tenosynovitis. The accurate differentiation of these clinical entities is of paramount importance to healing and recovery of function. Read More

Department of Emergency Medicine, Naval Medical Center, San Diego, California.

Background: Sialolithiasis with salivary gland obstruction can mimic more frequently occurring illnesses such as facial and dental infection and abscess. It is often difficult to discern the etiology of facial pain and swelling on physical examination alone, requiring advanced imaging in the emergency department.

Case Report: We describe the case of a 37-year-old man who presented with 5 days of worsening unilateral facial pain and swelling. Read More

Ultrasonography (US) is a reliable and useful diagnostic tool for the assessment of hip pathology. It depicts changes within the coxo-femoral joint (synovitis, erosions, osteophytes) and in the adjacent peri-articular tissues (calcifications, tendonitis, enthesitis, bursitis) in many rheumatic diseases (rheumatoid arthritis, spondyloarthritis, osteoarthritis, polymyalgia rheumatica ) and in some orthopaedic disorders (septic arthritis, trauma, abscess, painful hip after arthroplasty). It is commonly used both in adults and in children. Read More

Objectives: Soft tissue infections are a common presenting complaint in the emergency department (ED). The authors sought to determine the utility of ED bedside ultrasonography (US) in detecting subcutaneous abscesses.

Methods: Between August 2003 and November 2004, a prospective, convenience sample of adult patients with a chief complaint suggestive of cellulitis and/or abscess was enrolled. Read More

Researchers have described the use of bedside emergency ultrasound as an effective way to evaluate for and accurately drain potential abscesses. Similarly, descriptions exist of long bone fracture evaluation in the wrist and hands. Tendon injury can also be detected with ultrasound and exploration can be obviated or at least focused.

Complimentary to orthotopic liver transplantation (OLT), living donor liver transplantation (LDLT) is increasingly considered a therapeutic option in the therapy of end-stage liver disease. Accurate pre- and postoperative imaging is crucial for the transplantation success and represents an established part of the current evaluation algorithms. This article summarizes the most important requirements and the current imaging standards. Read More

As the role of the general surgeon continues to evolve, the surgeon's use of ultrasound imaging will surely influence practice patterns, particularly for the evaluation of patients in the acute setting. With the use of real-time imaging, the surgeon receives "instantaneous" information to augment the physical examination, to narrow the differential diagnosis, or to initiate an intervention. With select ultrasound examinations, the surgeon can rapidly evaluate adult and pediatric patients with an acute abdomen, especially those patients who are hypotensive. Read More

Purpose: To assess the diagnostic value of thoracic CT-scans in comparison with conventional chest radiographs in ICU-patients.

Methods: Chest radiographs and corresponding thoracic CT-scans of 25 consecutive surgical ICU-patients were reviewed and interpreted independently by two radiologists. We analyzed the additional information provided by CT-scans and the diagnostic and therapeutic relevance of these findings. Read More

Semin Respir Infect 1999 Mar;14(1):31-8

Department of Radiology, Beth Israel Deaconess Medical Center, Boston, MA 02215, USA.

Radiology plays a central role in the evaluation and management of pleural space infections. Conventional radiographs, including decubitus films, remain the primary radiological study in the detection of parapneumonic pleural effusions. Loculated collections develop as a result of visceral-to-parietal pleural adhesions and appear radiographically as longitudinally oriented, lenticular-shaped opacities. Read More

In one's attempt to arrive at the most accurate diagnosis in the critically ill, the selection of the most efficacious and rapid imaging modality can be problematic to clinicians, especially if the clinical presentation is confusing. The selection most often, is between US and CT. In general, US is advantageous in that it can be performed at bedside and is a faster and less costly examination. Read More

Neurol Med Chir (Tokyo) 1989 Aug;29(8):740-5

Twenty-five patients underwent bedside ultrasonographic examination through a postoperative skull defect, and the images were compared with axial computed tomography (CT) scans. The patients included 12 with cerebrovascular disease, two with brain tumor, one with a brain abscess, and 10 with head injury. Clear ultrasonographic images were obtained in all patients except one who had undergone a suboccipital craniectomy. Read More

Real-time sonographic findings in 20 infants with bacterial meningitis are reported. The spectrum of features included normal scans, ventricular enlargement, focal areas of increased cortical echogenicity, ventricular bands, and cerebral abscess. Areas of increased cortical echogenicity on sonography representing meningoencephalitis corresponded to areas of contrast enhancement seen on computed tomography (CT). Read More
