PIK3CA-related overgrowth spectrum, caused by mosaic mutations in the PIK3CA gene, is associated with regional or generalized asymmetric overgrowth of the body or a body part in addition to other clinical findings. Three-dimensional ultrasonography (3-D US) has the capability to display structural abnormalities in soft tissues or other organs, thereby facilitating identification of segmental overgrowth lesions. We present a case suspected of having a segmental overgrowth disorder based on 3-D US, whose chromosomal microarray result was abnormal, but apparently was not the cause of the majority of the fetus's clinical features...

Maternal autoantibodies to Ro/SSA are often linked to congenital heart block and rarely associated with structural defects. We describe the case of a fetus with anti-Ro-mediated second-degree block at 19 weeks, which progressed to a complete block, fibroelastosis, atrioventricular valve insufficiency, and semilunar valve stenosis/insufficiency at 20, 22, 24, and 26 weeks, respectively, although the fetus received transplacental anti-arrhythmic drugs. The 2150-g fetus was vaginally delivered at 35 weeks. An external pacemaker was inserted immediately after birth and replaced with permanent pacemaker at the age of 3 months...

A 56-year-old woman was admitted to our hospital because of amaurosis fugax. The carotid angiogram showed irregularly stenotic lesions of the left and right internal carotid arteries (ICAs), suggestive of dissection. Follow-up evaluation was performed by transoral carotid ultrasonography (TOCU) with contrast enhancement (CE), which yielded better vessel lumen and intramural hematoma visualization than color Doppler imaging. CE-TOCU is useful for evaluating ICA dissections that extends to the high cervical portion...

Paratesticular mesothelioma is a rare differential diagnosis in the presence of scrotal hydrocele. A 17-year-old boy presented with a 3-year history of progressive hydrocele. Sonography revealed a large left paratesticular mass within the hydrocele. Serum tumor markers were negative. Left hydrocelectomy was performed and pathological analysis of the epididymal mass revealed a well-differentiated papillary mesothelioma. We discuss the sonographic and pathological findings of this rare neoplasm.

PURPOSE: There is currently no standardized method for muscle shear wave elastography (SWE). The objective of this study was to investigate the effect of unit of measurement, depth, and probe load on the reliability of muscle SWE. METHODS: The vastus lateralis, biceps femoris, biceps brachii, and abductor digiti minimi muscles were scanned on 20 healthy participants. The SWE readings were measured in shear wave velocity (m/s) and Young's modulus (kPa). Three acquisitions of varying depths were acquired from vastus lateralis...

INTRODUCTION: Acromegaly is a rare, chronic, disfiguring, and debilitating disease caused, in 90% of cases, by a benign monoclonal growth hormone-secreting pituitary adenoma. The present study aimed to assess left ventricular (LV) rotational and twist mechanics in acromegalic patients and to compare their results to age- and gender-matched healthy controls. METHODS: The present study comprised 24 acromegalic patients, from which 4 were excluded due to insufficient image quality (mean age: 57...

PURPOSE: Pulmonary ultrasound (PU) examination at the point-of-care can rapidly identify the etiology of acute respiratory failure (ARF) and assess treatment response. The often-subjective classification of PU abnormalities makes it difficult to document change over time and communicate findings across providers. The study goal was to develop a simple, PU scoring system that would allow for standardized documentation, have high interprovider agreement, and correlate with clinical metrics...

PURPOSE: To explore the clinical significance of sonographic (US) diagnosis of fetal arachnoid cysts and to evaluate their prognosis. METHODS: Sixty fetuses deemed to have arachnoid cysts by prenatal US were included in this study. Data from serial US, prenatal and/or postnatal MRI, or post-mortem examinations were retrospectively analyzed. For live births, the developmental quotient scores were determined using the Gesell Developmental Scale. RESULTS: Thirty fetuses were diagnosed during the second trimester and another 30 fetuses were diagnosed in the third trimester...

The gallbladder and bile ducts are usually assessed initially with conventional gray-scale ultrasound (US). Contrast enhanced US (CEUS) is used when a diagnosis cannot be reached with conventional US. CEUS is easy to learn and perform. US contrast agents can be safely administered in patients with renal function impairment. In this pictorial essay the physics, examination technique and indications of CEUS for examining the gallbladder and bile ducts are reviewed. Gallbladder indications include elucidating normal variants, differentiating sludge from neoplastic lesions, benign and malignant pathology, infection, wall rupture and hemobilia...

Infection of a maternal urachal cyst during pregnancy is rare; Sonography is an important diagnostic tool that can help minimize maternal and fetal complications. We describe the case of a 35-year-old multiparous woman presenting in the third trimester with 2 weeks of fever, abdominal pain, and urinary symptoms. Imaging showed a 5-cm complex anterior midline mass, found intraoperatively to be eroding into the uterus. Sonographic imaging aided in the diagnosis and management of the urachal cyst, and antepartum sonographic measurements of the lower uterine segment helped to counsel regarding a trial of labor...

INTRODUCTION: Mustard gas (MG) is a chemical warfare agent widely used in the Iran-Iraq War. Its catastrophic effects on the lungs, eyes, and skin have been well studied. However, it also affects the cardiovascular system. We aimed to evaluate the long-term effect of MG on right ventricular (RV) function. METHODS: All patients presenting to the university clinics between May 2014 and September 2015 were consecutively evaluated to enter the study based on the inclusion criteria (documented proof of chemical injury, no past or present cardiovascular disease, not a current smoker, and no history of sleep apnea)...

Spontaneous ruptures of the plantar fascia are uncommon injuries. They typically occur at its calcaneal insertion and usually represent a complication of plantar fasciitis and local treatment with steroid injections. In contrast, distal ruptures commonly result from traumatic injuries. We describe the case of a spontaneous distal rupture of the plantar fascia in a 48-year-old woman with a low level of physical activity and no history of direct injury to the foot, plantar fasciitis, or steroid injections.

Diagnosis of fetal spinal dysraphism is a challenge. It is difficult to distinguish between a meningocele, myelomeningocele, and a recently described entity called limited dorsal myeloschisis (LDM). Although myelomeningocele is associated with a poor prognosis, LDM can have a good outcome. We present a case of prenatally diagnosed LDM. Because sonographic examination revealed a round, cystic, septated cervical mass without associated cerebral anomalies, the lesion was initially considered an isolated meningocele...

PURPOSE: To investigate the relationship between the location of echogenic intracardiac foci (EIFs) and fetal cardiac anomalies in our patient population. METHODS: We performed a retrospective study of the clinical files of fetuses who underwent an echocardiographic examination at our fetal cardiac medical center from August 2010 to August 2016. Fetuses were grouped by EIF location (left ventricle [LV], right ventricle [RV], or bilateral ventricles [BVs]). The maternal age, reason for referral, and cardiac anomalies in the three groups were analyzed...

Lateral facial cleft is a rare congenital anomaly, but all affected infants require surgery under general anesthesia. Conventional 2-dimensional coronal view of the face, which is typically used for identification of facial clefts, has limitations with regard to detection of this anomaly. We describe a case of prenatal diagnosis of isolated lateral facial cleft made with 3D sonography and highlight the importance of this tool in the diagnosis of this rare facial deformity.

Fetus in fetu is an extremely rare congenital anomaly. We describe the perinatal diagnosis and management of a fetus with oropharyngeal and cervical fetus in fetu. High-resolution ultrasonography with 3-dimensional rendering can identify increased risks of airway obstruction in utero. Early identification allows a multidisciplinary team to be assembled for a scheduled ex utero intrapartum treatment procedure. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound, 2017.

An ectopic thyroid gland results from the abnormal migration of the thyroid in the course of its development. Primary ectopic mediastinal thyroid is very rare and occurs in less than 1% of all goiters that can be surgically excised. Ectopic thyroid tissue has a characteristic sonographic appearance as smooth-bordered, homogeneous, hypoechoic tissue with fine specular echoes. We report 3 cases of mediastinal ectopic thyroid diagnosed by endobronchial ultrasound-guided transbrochial needle aspiration biopsy.
