We present a case of infantile myofibromatosis of the lung detected at 32 weeks' gestation. The fetus was monitored with weekly ultrasound examinations measuring the mass size and amniotic fluid index. On day 2 after delivery, due to respiratory distress, an exploratory thoracotomy was undertaken and the mass was resected. © 2013 Wiley Periodicals, Inc. J Clin Ultrasound, 2013;
Sonographic diagnosis of bilateral pneumothorax following an acupuncture session.
We present the case of a 57-year-old woman who presented with the acute onset of chest pain and dyspnea, which started while undergoing acupuncture for neck pain. A bedside ultrasound revealed bilateral pneumothoraces, which were confirmed radiographically. We discuss the details of the case, the sonographic features of pneumothorax, and the role of bedside ultrasonography in the assessment of an acutely dyspneic patient. © 2013 Wiley Periodicals, Inc.

Atherosclerotic renal artery stenosis is a frequent cause of arterial hypertension and/or allograft dysfunction after kidney transplantation and is usually located at the iliac artery anastomosis. Fibromuscular dysplasia is a less frequent, nonatherosclerotic, vascular disease, inducing stenosis at the proximal/mid-distal part of the renal artery. We report the case of a 44-year-old woman, in whom serum creatinine concentration increased and arterial hypertension developed 3 months after renal transplantati...
BACKGROUND: Myocardial functional recovery after revascularization is considered the "gold standard" for myocardial viability (MV) assessment. However, the patency of the revascularized coronary artery affects myocardial functional recovery in patients subjected to coronary artery bypass grafting (CABG). The influence of graft patency on viability results has not been widely studied. PURPOSE: We evaluated the effect of graft patency on the prediction of MV after CABG by myocardial contrast echocardiography...
PURPOSE: To identify patients with significant coronary artery disease by the noninvasive quantification of myocardial wall stress in diastole. METHODS: We studied 60 male subjects in sinus rhythm with significant (n = 30) or moderate (n = 30) proximal left anterior descending coronary artery stenosis, and 30 healthy subjects (control group). The average end-diastolic wall stress was estimated at left ventricle anterior and interventricular septum wall segments from regional wall thickness, meridion...
We present a case of a biliary-arterial communication as a consequence of the placement of an internal-external biliary drainage catheter in a liver transplant patient diagnosed on contrast-enhanced ultrasound using a novel application by injecting microbubble contrast into the catheter tube. We postulate that this method may be sensitive in identifying occult communications between the biliary tree and the vascular compartment when a catheter drain is positioned, and there is hemobilia or unexplained sepsi...
Hyperemesis gravidarum is a serious systemic disorder of pregnant women characterized by intractable vomiting resulting in metabolic, biochemical, and hematologic changes. Enteral nutrition has been used successfully and has a lower complication rate than parenteral nutrition. Tube feeding requires location of the feeding tube tip before the infusion of nutritional substance is started. We report a case of assisted feeding tube tip location using real time sonography in a pregnant women treated for hypereme...
The prenatal detection in the second trimester of pregnancy of a fetus with craniosynostosis, wide metopic suture, and wormian bone associated with bowing of the long bones, unilateral short femur, and focal fibula deficiency is reported. These ultrasonographic findings when not supported by a diagnostic molecular biology result represent a prenatal dilemma in term of both parent's counseling and management of potential overlapping skeletal diseases.© 2012 Wiley Periodicals, Inc.
PURPOSE.: Acoustic peak rarefaction pressure (APRP) is the main factor that influences ultrasound-enhanced thrombolysis. We sought to determine whether recanalization rate and functional outcomes in the Transcranial Ultrasound in Clinical SONothrombolysis (TUCSON) trial could be predicted by estimated in vivo APRP. METHODS.: We developed an acoustic attenuation model to estimate the in vivo APRP at the arterial occlusion site in each subject of the TUCSON trial with CT scans eligible for measurements. Varia...
A case of asymptomatic isolated double-chambered right ventricle in an adult man.
Double-chambered right ventricle is a rare congenital heart disease. An anomalous muscle band divides the right ventricle into two cavities, causing a variable degree of obstruction. Most cases of double-chambered right ventricle are diagnosed and treated during childhood, whereas cases of initial presentation during adulthood are very rare. We report a case of asymptomatic isolated double-chambered right ventricle incidentally found in an adult man. © 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 2012.
BACKGROUND.: Color Doppler ultrasound (CDUS) has a potential of early detection of post biopsy bleeding. We describe CDUS guidance in planning, acquisition, and, in the case of bleeding, compression of the needle tract in biopsy procedures of kidney transplants. METHODS.: Eighty-three kidney transplant biopsy procedures performed on clinical indication were performed in 71 adult patients, 25 women, mean age 51 years, using CDUS and 18-G biopsy needles. Bleeding needle tracts were compressed using CDUS guida...
Correlation between prenatal and postnatal penile and clitoral measurements.
BACKGROUND.: A correlation between prenatal and postnatal penile and clitoral sizes has not been reported. These data would substantiate the ability of prenatal ultrasound (US) scan to predict postnatal measurements. The aims were to correlate prenatal and postnatal penile and clitoral measurements and to ascertain the possible advantage of using prenatal penile width rather than length to predict postnatal measurements. METHODS.: This was a longitudinal study. Fetal penis and clitoris were measured by high...
Sonographic diagnosis of fetal intestinal volvulus with ileal atresia: A case report.
Fetal intestinal volvulus is a rare life-threatening condition usually manifesting after birth with most cases being associated with intestinal malrotation. It appears on prenatal sonography (US) as a twisting of the bowel loops around the mesenteric artery, leading to mechanical obstruction and ischemic necrosis of the bowel. We report a case of intrauterine intestinal volvulus with ileal atresia, suspected when US revealed a typical "whirlpool" sign at 37 weeks' gestation, with a segment of markedly diste...
Blunt chest trauma can cause serious complications, but coronary artery occlusion is rare. In a 19-year-old man, 40 days after a motorcycle accident, comprehensive echocardiography detected left anterior descending artery occlusion and left ventricular dysfunction, which was confirmed by coronary angiography and ventriculography. Echocardiography was also able to confirm restored left anterior descending artery flow and improved left ventricular function after coronary artery bypass grafting. © 2012 Wiley...
First trimester transabdominal chorionic villus sampling-Does the needle matter?
PURPOSE: To compare first-trimester transabdominal chorionic villus samples (TA-CVS) when obtained by 20-gauge amniocentesis versus lancet needles. METHODS: This is a retrospective study of all women with viable singleton pregnancies undergoing TA-CVS from 01/01/2009 to 03/31/2011. All CVS were performed by a single operator using a freehand technique and amniocentesis needles from 01/01/2009 to 08/31/2010 and lancet needles from 09/01/2010 to 03/31/2011. All samples were processed by the same laboratory. R...
PURPOSE: Assess patient discomfort during two different methods of injection of Morton's neuroma. METHODS: Sixty-eight patients referred for ultrasound-guided injection of Morton's neuroma had punctures performed dorsal or plantar to the interdigital skin crease, with and without preliminary subcutaneous local anesthesia (LA). Patients rated discomfort during skin puncture (SP) and needle advancement (NA) using a visual analog scale. RESULTS: Average pain score was 4.4 ± 2.3 (1 SD) for the plantar approach...
Pseudoaneurysm of the genicular artery after wound closure using a skin stapler in a child.
A 9-year-old child with a left humerus fracture also had minor skin cuts on the right knee, which were closed with a skin stapler. After 1 week, a medial superior genicular artery pseudoaneurysm developed, which was treated by ultrasound-guided compression. This case illustrates a unique complication of the use of a skin stapler device.© 2012 Wiley Periodicals, Inc. J Clin Ultrasound 2012.
Prenatal sonographic diagnosis of mature renal teratoma: A case report.
Renal teratoma is an extremely rare condition found in adolescents and young adults. Here, we report a case in which renal teratoma was diagnosed by fetal ultrasound examination. To our knowledge, this is the first report to describe the imaging manifestation of renal teratoma in prenatal diagnosis.© 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 2012;
Pneumopericardium diagnosis by point-of-care ultrasonography.
Focused cardiac ultrasound by the emergency physician has become a fundamental tool to expedite the diagnostic evaluation of the patient at bedside. We report the case of a patient admitted to the emergency department for respiratory distress. He was examined by an emergency physician who performed a bedside echocardiography. Bright spots were seen rapidly moving along the pericardial layer during diastole with comet-tail artifacts extending across the whole image of the heart and disappearing during systol...
We report the uncommon case of a pericardial cyst with unremitting compression of the left ventricle during the whole cardiac cycle, but normal ejection fraction. On CT scan, the cyst was found at an atypical location, lateral to the pulmonary artery, the ascending aorta, and the right ventricular outflow tract in the left anterior mediastinum. The radio-density of the cyst was 41 Hounsfield units (HU), higher than other cases reported in the literature. As the cyst was stable, conservative treatment was ad...
Sonography of the adrenal glands in the adult.
Although its capability has been overlooked, sonography can be a useful screening tool for adrenal lesion in adults. In this article, we discuss scan technique, patient positioning, and anatomic consideration for adrenal sonography in adults and illustrate sonographic appearance of normal adrenal gland as well as adrenal tumors and tumor-like lesions. © 2012 Wiley Periodicals, Inc.

We report the case of a 6-year-old girl presenting with acute appendicitis complicated by perforated appendix, followed by perihepatic abscess associated with ectopic appendicoliths. CT findings were initially suspicious for an intrahepatic abscess with internal calcifications. However, on sonography the abscess appeared to be in a perihepatic location. Perihepatic abscess associated with a dropped or retained appendicolith has been rarely reported. Awareness of the possibility of a perihepatic abscess as a...
An unusual case of myocardial noncompaction involving both ventricles-Case report.
Noncompaction of ventricular myocardium (NCVM) is a rare congenital cardiomyopathy characterized by numerous excessively prominent trabeculations and intertrabecular recesses in the myocardium without any other cardiac structural abnormality. Transthoracic echocardiography is the imaging modality of choice for diagnosing NCVM. Although this disease commonly affects the left ventricle, the right ventricle or both ventricles can rarely be affected. We report the case of an 18-year-old male patient with NCVM i...
Intraabdominal extrapulmonary sequestration is seen very rarely. When a left suprarenal mass is detected in prenatal sonography, vascularization of the lesion should be evaluated with color Doppler sonography. We present a case of intraabdominal extrapulmonary sequestration that was diagnosed by color Doppler ultrasound at 22 weeks' gestation. © 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 2012.
Twin reversed arterial perfusion sequence is a rare anomaly of monochorionic multiple pregnancies affecting 1 of 35,000 pregnancies and 1% of monochorionic twin pregnancies. In this condition the affected twin has lethal malformations including poor or absent heart development and is reversely perfused by a structurally normal co-twin. We report a case of a 21-year-old woman with a monochorionic twin pregnancy affected by twin reversed arterial perfusion sequence. This case highlights the therapeutic option...
