OBJECTIVES/HYPOTHESIS: Ultrasonography is an emerging clinical tool to study the dysfunction of swallowing muscles. This was the first sonographic study to assess the relationship between suprahyoid muscle contraction, hyoid bone displacement, and penetration-aspiration status (PAS) during swallowing in nasopharyngeal carcinoma (NPC) patients treated with radiotherapy (RT). The study also aimed to establish reliability data for the sonographic technique described. STUDY DESIGN: Cross-sectional study...

Squamous cell carcinoma (SCC) arising from the breast is an exceedingly rare disease; even more rare is SCC arising from a breast implant capsule. So far, only five cases have been reported in the literature. We present the case of a 65-year-old woman with a remote history of breast augmentation using foam covered silicone implants performed in 1979. In 2010, she presented with progressive enlargement of her left breast with associated pain. Mammographic and sonographic evaluation demonstrated fluid surrounding the implant without evidence of abnormal masses...

Renal transplant scintigraphy, performed in a 23-year-old man who had renal graft from a living donor, showed nearly normal perfusion and moderately low function of the graft. But the margins of the graft were blurred, and it was interestingly appearing enlarged late in the study. Ultrasound demonstrated a hypoechoic rim surrounding the whole kidney. Biopsy revealed necrosis besides normal cortical tissue. Necrosis was thought to be limited to the subcapsular cortical area. It should be considered that these scintigraphic findings could be due to greatly reduced and delayed perfusion of edematous subcapsular necrotic area of the graft even in normal perfusion images...

OBJECTIVE: An anorectal malformation (ARM) in neonates requires urgent surgery, with the type of surgery being dependent on the type of malformation (low, intermediate, or high). Distal rectal pouch and perineum (pouch-perineum) distance is reported to be useful for differentiating the type of ARM; however, the impact of an opened fistula on pouch-perineum distance is not well known. The purpose of this study was to evaluate the difference in pouch-perineum distance between neonates with a low-type ARM with and without an opened fistula...

Introduction: Both B-mode ultrasound and contrast-enhanced ultrasound (CEUS) are well established procedures when diagnosing traumatic splenic ruptures (TSR). To date, there are no data about CEUS patterns in spontaneous splenic ruptures (SSR). It remains unknown whether TSR and SSR differ with respect to clinical characteristics, B-mode and CEUS characteristics. Patients and Methods: Between 12/2003 and 2/2010, n=33 SSRs and n=29 TSRs were diagnosed in a tertiary referral center...

Meniscocapsular separation describes detachment of the meniscus from the knee joint capsule. Diagnosis is challenging with conventional examination and imaging methods. We report a case of an 18-year-old female softball catcher with unrevealing MRI despite continued left knee locking and discomfort with deep squatting. Meniscocapsular separation was revealed only on dynamic sonographic exam, where knee flexion revealed a 3.1 mm gap that developed between the capsule and peripheral meniscus. Arthroscopy confirmed the sonographic findings, and repair resulted in complete resolution of symptoms...
