An ileal adenomyoma leading to intussusception is very rare. We describe the case of a 4-month-old boy who presented with hematochezia. He was diagnosed with ileal adenomyoma by sonography, which was confirmed by histopathology. This case confirms that sonography is the preferred modality to diagnose an ileal adenomyoma.

Isolated fetal ascites and cri-du-chat syndrome (CdCS; OMIM #123450) are two very rare conditions that, to our best knowledge, have never been reported together. Here, we describe a case of isolated fetal ascites detected in the first trimester ultrasound, with no other remarkable signs. After an extensive work-up (fetal ultrasound, serologies, Coombs test, and NIPT), an amniocentesis was performed and revealed an abnormal karyotype of 46,XX,del (p15.2), characteristic of CdCS. We hypothesize that isolated fetal ascites has to be considered an antenatal ultrasonographic marker for CdCS, a finding that should be confirmed in further cases...

Harlequin ichthyosis is the most severe form of autosomal recessive congenital ichthyoses. So far, there are only a few reports of prenatal diagnosis in the literature, as prenatal sonographic features are quite subtle. We report a case of prenatal diagnosis of Harlequin ichthyosis on third-trimester sonographic examination in a consanguineous couple with no history of the disease and describe its characteristic sonographic features.

PURPOSE: Macrovascular endothelial function is commonly assessed using flow-mediated dilation (FMD) and is nitric oxide (NO) dependent. However, the vasoreactivity to low flow during the FMD protocol may complement FMD interpretation. This study aimed to investigate in adolescents: (1) the day-to-day reliability of low-flow-mediated constriction (L-FMC) and composite vessel reactivity (CVR); and (2) the relationship between L-FMC and FMD. METHODS: A retrospective analysis of data on 27 adolescents (14...

The aim of this study was to explore changes in the common carotid arterial wall elasticity after smoking cessation. Carotid artery ultrasonographic examination was performed in 136 patients, then 1 or 2 years after smoking cessation. We used echo-tracking (ET) to measure stiffness index (β), pressure-strain elasticity modulus (Ep), arterial compliance (AC), augmentation index (AI), and local pulse wave velocity (PWVβ). Patients were divided into four groups based on whether or not they successfully stopped smoking (groups M and N, respectively) and whether (groups M2 and N2, respectively) or not (groups M1 and N1, respectively) they showed comorbidities...

Primary malignant pericardial mesothelioma (PMPM) is an extremely rare tumor, which may appear as a localized or a diffuse mass encasing the heart. Diffuse PMPMs have a poor prognosis due to the difficulty of surgical excision, whereas localized PMPMs have clear margins, thus facilitating surgical excision. Timely diagnosis and proper treatment are crucial for a favorable prognosis. Eight cases of localized PMPMs have been reported so far, but their characteristics have not been fully described. Herein, we present a patient with localized PMPM and describe the diagnosis methods, treatment, and outcomes of these tumors...

Ross Kruger, Simon Freeman
Splenosis is an unusual condition representing auto-transplantation of splenic tissue following splenic trauma or surgery. When detected on imaging studies, the splenosis deposits are usually misinterpreted as pathological masses. We present a case where a pelvic mass incidentally visualized on an MRI examination, was proven to represent a deposit of splenosis by contrast enhanced ultrasound (CEUS). CEUS demonstrated persistent late-phase enhancement characteristic of splenic tissue. Ultrasound practitioners should be aware of this condition when an unusual abdominal or pelvic mass is encountered in a patient with a history of splenic trauma or surgery...

Fetal lipomyelomeningocele was suspected during the second-trimester ultrasound and confirmed by magnetic resonance imaging. The pregnancy took its course and a term neonate was delivered. At 2 years of age lipomyelomeningocele surgical removal was performed. The patient is now 4 years old and, despite neurogenic bladder, is a healthy boy with normal psychomotor development for his age. This case illustrates the favorable prognosis of this entity and the importance of prompt diagnosis and multidisciplinary counseling...

Kirsteen R Burton, Bo-Yee Ngan, Oscar M Navarro
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare, benign neoplasm of neural crest origin more commonly seen in the craniofacial region. We report a case of MNTI of the epididymis in a 6-month-old male child with emphasis on the sonographic appearance which has not been previously described. In this case, the mass was inseparable from the testicle and therefore the differential diagnosis considered both extratesticular and intratesticular masses. MNTI should be added to the differential diagnosis of scrotal masses, particularly if they present in a child younger than 12 months of age...

Metastasis to the thyroid is very rare in hepatocellular carcinoma (HCC) and only a few cases have been reported. Herein, we report a rare case of metastatic HCC to the thyroid in a 63-year-old man and discuss the various radiologic findings. Computed tomography (CT) revealed a heterogeneous enhancing mass that had invaded the thyroid cartilage in the left upper thyroid, compressing the airway. Ultrasonography (US) showed a heterogeneous hypoechoic mass with increased vascularity in the peripheral portion. The mass showed focal intense uptake on positron emission tomography-computed tomography (PET-CT)...

Contrast-enhanced voiding urosonography (ceVUS) has been recognized as a child-friendly examination with high diagnostic accuracy for vesicoureteric reflux detection. A single bolus and the infusion techniques of ceVUS are described. Insufficient bladder contrast opacification during the filling phase and premature destruction of SonoVue microbubbles might occur. Data regarding SonoVue's features, doses, bladder contrast opacification, US bladder parameters, urine catheter, antibiotic prophylaxis, and childrens behaviors were collected to discover the possible causes of the contrast vanishing observed during bladder filling in 10% of examinations and in the later phase of ceVUS in 5% of examinations...

Non-compaction of the left-ventricular myocardium is an extremely rare cardiomyopathy. The most common clinical manifestations are heart failure, ventricular arrhythmia, thromboembolism, and sudden cardiac death. The condition is diagnosed by two-dimensional echocardiography or magnetic resonance imaging. We report a rare case of a 55-year-old man with coexistence of left ventricular non compaction cardiomyopathy, significant coronary artery disease and massive thrombus formation within recesses in left ventricular cavity...
