Injection laryngoplasty under ultrasonographic control.

BACKGROUND: Cervical ultrasound allows real-time visualization of the laryngeal structures. We describe its application for injection laryngoplasty in the voice clinic. METHODS: Hyaluronic acid infiltration of the vocal fold under ultrasonographic control. CONCLUSIONS: With this technique, the position of the needle in the depth of the vocal fold and its spatial relations with nearby structures can be assessed. This allows for an accurate infiltration of the material in contrast to other techniques and avoids discomfort related to the gag reflex with nasofibrolaryngoscopy. No specific complications have been observed so far, however, this technique may be difficult in cases with calcified cartilages or uncooperative patients.

Case 224: Cardiac Involvement in Erdheim-Chester Disease.

History A 61-year-old man with no relevant medical history was admitted to the emergency department with symptoms of congestive heart failure and a 1-week history of chest pain, progressive dyspnea, abdominal swelling, bipedal edema, and anorexia. Laboratory test results, including complete blood count and electrolyte, creatinine, creatine phosphokinase, and troponin T levels were normal. Electrocardiographic findings were unremarkable. Initial chest radiography showed an enlarged heart with bilateral pleural effusion. Transthoracic echocardiography revealed an irregular right atrial mass and moderate to severe pericardial effusion. The patient subsequently underwent computed tomography (CT) of the chest, abdomen, and pelvis followed by cardiac magnetic resonance (MR) imaging for further evaluation of the atrial mass. Because of the suspected diagnosis, conventional radiography of the skeleton was performed.

MR imaging-based assessment of the female pelvic floor.

Pelvic floor weakness is a functional condition that affects the anatomic structures supporting the pelvic organs: fasciae, ligaments, and muscles. It is a prevalent disorder among people older than 50 years, especially women, and may substantially diminish their quality of life. Many complex causes of pelvic floor weakness have been described, but the greatest risk factors are aging and female sex. Pelvic floor weakness can provoke a wide range of symptoms, including pain, urinary and fecal incontinence, constipation, difficulty in voiding, a sense of pressure, and sexual dysfunction. When the condition is diagnosed solely on the basis of physical and clinical examination, the compartments involved and the site of prolapse are frequently misidentified. Such errors contribute to a high number of failed interventions. Magnetic resonance (MR) imaging, which allows visualization of all three compartments, has proved a reliable technique for accurate diagnosis, especially when involvement of multiple compartments is suspected. MR imaging allows precise evaluation of ligaments, muscles, and pelvic organs and provides accurate information for appropriate surgical treatment. Moreover, dynamic MR imaging with steady-state sequences enables the evaluation of functional disorders of the pelvic floor. The authors review the pelvic floor anatomy, describe the MR imaging protocol used in their institutions, survey common MR imaging findings in the presence of pelvic floor weakness, and highlight key details that radiologists should provide surgeons to ensure effective treatment and improved outcomes.
