Nondysraphic intramedullary lipomas of the spinal cord are rare, and there are currently no reports of their observation in utero. Here, we present the sonographic (US) findings in such a case. Four intraspinal hyperechoic masses were observed on US on the dorsal aspect of the fetal spine in a 30-year-old woman at 30 weeks' gestation. Findings were consistent with those of prenatal MRI and were confirmed on autopsy after induced abortion. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound, 2017.

PURPOSE: To evaluate the effects of chronic cigarette smoking on total cerebral blood flow in healthy adults by Doppler ultrasonography (US). METHODS: We evaluated 50 smoker (median age 29) and 50 nonsmoker (median age 28) healthy, 20- to 40-year-old subjects without any cardiovascular and cerebrovascular disease. Peak systolic maximal blood flow velocity (PSV), end-diastolic maximal blood flow velocity (EDV), time-averaged mean blood flow velocity (TAMV), resistance index (RI), and pulsatility index (PI) were measured in the left and right carotid and vertebral arteries, and total cerebral blood flow volume was calculated...

We report a case of left atrial extrinsic compression caused by an esophageal food bolus in a patient presenting with acute heart failure. Transthoracic echocardiography along with contrast-enhanced CT showed evidence of esophageal dilation producing left atrial compression. Esophageal endoscopy and fragmentation of the bolus, allowing the accumulated food to descend into the stomach, produced a rapid improvement of hemodynamic and clinical status. © 2017 Wiley Periodicals, Inc.

A retained urethral foreign body is an uncommon presentation in the Emergency Department. The diagnosis and treatment of retained urethral foreign bodies are determined by their size, location, shape, and mobility and often require specialty consultation and operative intervention. In this case of a 74-year-old man with a self-inserted, retained urethral foreign body, we present the utility of a bedside ultrasound to detect the depth, size, and distance from the meatus of the object to guide the approach to extraction of the object at the bedside in the Emergency Department...

Hydatid disease is a human parasitic infection caused by the larval stage of Echinococcus granulosus. The most common locations for hydatid cysts are the liver and lungs. Cardiac involvement is rare, and isolated cardiac hydatid cysts are even more unusual. We report the case a 48-year-old female patient with an isolated huge cardiac hydatid cyst involving both the left ventricular free wall and the pericardium, and presenting with atypical chest pain. © 2017 Wiley Periodicals, Inc.

Myxomas are the most common cardiac primary tumors; however, left ventricular myxomas are extremely rare. We describe a young female patient with a giant left ventricular myxoma causing partial obstruction of the left ventricular outflow tract, who underwent successful surgical resection. Real-time three-dimensional echocardiography yielded incremental value to two-dimensional echocardiography by allowing better assess of the true size, extent, attachment, and morphology of the tumor. © 2017 Wiley Periodicals, Inc...

The accuracy of color Doppler ultrasonography (CDU) is hampered by the presence of arterial wall calcifications. B-flow imaging may overcome these limitations. We present a case of a severely calcified stenosis of the right common femoral artery (CFA) diagnosed with the aid of B-flow imaging. Both the CT angiography scan and CDU were limited by the presence of diffuse dense arterial calcifications. B-flow imaging showed a >75% stenosis of the CFA. B-flow imaging appears to improve the accuracy of CDU in the presence of calcified stenosis of the CFA...

We report a case of a secundipara with heterotopic cesarean scar pregnancy (HCSP) treated with potassium chloride injection into the ectopic embryo followed by sac aspiration. The remaining "mass" increased in size threefold and was surrounded by a rich vascular network. An arteriovenous malformation was suspected; however, appropriate treatment was precluded because of the viability of the ectopic gestation. Sonographic examination revealed a morbidly adherent placenta, and attempt to resect the mass laparoscopically was complicated by bleeding that required hysterectomy...

A 38-year-old woman was diagnosed with systemic lupus erythematosus and received immunosuppressive therapy. After 6 months of treatment, workup for low-grade fever yielded elevated enzyme-linked immunosorbent assay titers for Aspergillus antigen in serum and ascites, leading to the diagnosis of disseminated aspergillosis. Transthoracic echocardiography revealed a claviform vegetation attached to the left ventricular anterior septum. Two days after the start of antifungal Amphotericin-B therapy, the patient suffered from several neurologic disorders...

Endocervical varices are a rare cause of obstetrical hemorrhage. Usually presenting in the second and third trimesters, bleeding varices often require pregnancy termination or indicated preterm birth via cesarean delivery. Our patient experienced variceal hemorrhage at 12 weeks' gestation in a dichorionic twin pregnancy conceived through in vitro fertilization. A low-lying placenta resolved at 19 weeks followed by variceal regression at 22 weeks' gestation. Endocervical varices causing first-trimester hemorrhage may regress with resolution of a coexisting low placental implantation, permitting planned vaginal delivery, despite progressive hemodynamic changes of pregnancy...

BACKGROUND: To evaluate the diagnostic performance of ultrasonography for screening of a population at risk for deep vein thrombosis (DVT) in a post-disaster setting. METHODS: Ultrasonography was applied as a screening technique to the residents of a temporary housing facility who were displaced following the Great East Japan Earthquake. Thirty DVT screening sessions were held from April 2013 to June 2015. Individuals were invited to participate if they were identified as "high risk" for DVT, defined as those with low activity levels, a history of lower limb trauma, baseline lower limb pain or swelling, a cancer-bearing status, or a history of venous thromboembolic event...

BACKGROUND: To investigate the agreement between Kupffer phase of Sonazoid contrast-enhanced sonography (CEUS) and hepatobiliary phase of gadoxetic acid-enhanced MRI in the evaluation of focal liver lesions (FLLs). METHODS: One hundred fifty-four FLLs in 154 patients who underwent both Sonazoid CEUS and gadoxetic acid-enhanced liver MRI were included in this retrospective study. FLL visibility on the Kupffer-phase images was graded as one (invisible or isoenhancing), two (vaguely visible or vaguely hypoenhancing), or three (clearly visible or clearly hypoenhancing), and that on the hepatobiliary-phase images of MRI was graded as one (invisible or hyper/isointense), two (vaguely visible or weakly hypointense), or three (clearly visible or strongly hypointense)...
