High-intensity focused ultrasound treatment for intra-abdominal desmoid tumors: a report of four cases
Abstract Desmoid tumors are rare clonal fibroblastic proliferations that can arise at abdominal or extra-abdominal sites. Complete surgical resection is the primary treatment for resectable desmoid tumors, but a high rate of local recurrence has been reported even after complete resection. For patients with a recurrent tumor, the goals of treatment are to control the recurrence, maintain quality of life, and prolong survival. Radiofrequency ablation, radiotherapy, chemotherapy, and other medical therapies can be used as alternative methods, but there are considerable controversies over the roles of these methods i...

Ultrasonographic characteristics of congenital corneal staphyloma
Abstract This case report describes the ultrasonographic characteristics of congenital corneal staphyloma (CCS) in a neonate on the birth day, with a massively staphylomatous and ectatic left cornea, which was forward protrusive between the eyelids. Ultrasound biomicroscopy (UBM) revealed the cornea of the left eye as thin and ectatic, with an irregular contour and unidentified layers. The anterior chamber was extraordinarily deep. Apart from histology, UBM can be used for understanding the microstructure of the anterior ocular segment, which may directly guide the diagnosis of CCS in a timely manner. (Source: Jou...

Two cases of immunoglobulin G4-related sclerosing cholangitis in which transabdominal ultrasonography was useful in diagnosis and follow-up observation
Abstract Immunoglobulin G4-related disease (IgG4-RD) represents a group of disorders that share features of inflammation, plasma cell infiltrates, and fibrosis. Sclerosing cholangitis is a disorder involving inflammation, scarring, and destruction of the bile ducts. IgG4-related sclerosing cholangitis (IgG4-SC) has been proposed as a bile duct lesion associated with IgG4-RD. This disease entity can be distinguished from other types of sclerosing cholangitis and classified into four types based upon the region of strictures revealed by cholangiography. Here, we present two cases in which the finding of bile duct wa...

Solitary fibrous tumor of the breast: a case report and review of the literature
Abstract Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms that can be benign or malignant. SFTs have been most often documented in the pleura. Recently, involvement of extrapleural sites such as the abdomen, musculoskeletal soft tissue, upper respiratory tract, mediastinum, and head and neck were reported. Less than 15 cases of SFT of the breast have been reported. Here, we report a case of a pathologically proven SFT of the breast and review the literature on the radiologic findings. US imaging showed an oval, well-circumscribed, hypoechoic solid mass. A solitary fibrous tumor of the breast is a very...

Successful diagnosis of pericardial rupture caused by blunt chest trauma using contrast ultrasonography
Abstract A 65-year-old male developed acute myocardial infarction due to coronary artery dissection and tricuspid valve injury after blunt chest trauma. Acute myocardial infarction was treated by coronary artery intervention; however, refractory heart failure with pleural effusion remained. The first transthoracic echocardiography (TTE) on admission failed to clearly visualize the tricuspid valve and right ventricle due to poor image quality. A follow-up TTE with contrast ultrasonography revealed pericardial rupture in addition to tricuspid regurgitation. Ruptures of the tricuspid papillary muscle and pericardium ...

Abstract The patient was a 38-year-old primigravida woman with a previous history of myomectomy via laparotomy. At 30 weeks of gestation, she visited our emergency center because of sudden severe abdominal pain. Routine focused assessment with sonography for obstetrics (FASO) indicated no echo-free space at Douglas’ pouch or between the spleen and kidney; however, echo-free spaces were visualized around the intestinal tract and at Morrison’s pouch. Therefore, a diagnosis of hemoperitoneum due to uterine rupture was suspected, and emergency cesarean section was planned. During surgery, a small defe...

Weighted Capon beamformer combined with coded excitation in ultrasound imaging
Abstract Background Capon-based beamformers are well-known methods to improve the SNR and quality of medical ultrasound images. Furthermore, they can improve the resolution of the images unexpectedly more than conventional DAS beamformers. Another method used in radar, sonar, and ultrasound imaging to increase the SNR is coded excitation with linear frequency-modulated signal (chirp). Method In this paper, we illustrate that the combination of coded excitation with a Capon beamformer provides better resolution and higher SNR. However, this combination su...

Prenatal diagnosis and postnatal outcome of persistent right ductus arteriosus: a report of three cases
Abstract The ductus arteriosus is a fetal vascular connection between the main pulmonary artery and aorta that diverts blood away from the pulmonary bed. Left and right ductus arteriosi emerge from embryological aortic arches. In normal embryologic cardiac development, both right aortic and ductal arches regress and the left ones persist. Persistent right ductus arteriosus (rDA) is one of the congenital anomalies of the ductal arch. In this paper, we report three cases of persistent right ductus arteriosus with right aortic arch.
