Continuous fetal head flexion as a marker for prenatal diagnosis of lethal multiple pterygium syndrome: a case report
AbstractLethal multiple pterygium syndrome (LMPS) is a fatal hereditary disease associated with abnormalities such as pterygium-induced congenital contractures. Fetal hydrops is present in more than half of all patients with LMPS, and all patients with LMPS are either stillborn or die in the early neonatal period. Ultrasonography findings for the prenatal diagnosis of LMPS include the detection of cutaneous webbing at multiple joints, multiple joint contractures, absent limb movement, and increased nuchal translucency. Here, we describe a patient who was diagnosed as having LMPS due to continuous fetal head flexion, despit...

Modern role of clinical ultrasound in liver abscess and echinococcosis
AbstractIn the Western world, liver abscesses are predominantly of pyogenic origin and can present a wide range of ultrasonographic features, from a solid mass to a cystic cavity. Amoebic abscesses are endemic in tropical areas and typically round single lesions. Echinococcal cyst is diagnosed by ultrasound (US). Serology is particularly useful when pathognomonic US features are absent. Treatment is determined based on the WHO ultrasonographic classification, and puncture, aspiration, injection, re-aspiration (PAIR) is a US-guided therapeutic option. Hepatic alveolar echinococcosis presents on US as a pseudotumoral mass fr...

Contrast-enhanced ultrasound in diagnosis of primary hepatic angiosarcoma
AbstractPrimary hepatic angiosarcoma (PHA) is a rare malignant tumor that occurs mainly in the elderly, with almost no specific symptoms or tumor markers. Information on the imaging characteristics of this tumor is limited due to its rarity. Therefore, it is difficult to diagnose PHA. So far, its definite diagnosis depends on histopathologic examination combined with immunohistochemical results. Patients with PHA have a poor prognosis in spite of surgical resection of this tumor. In this case report, we present a 72-year-old woman with PHA, focusing on the imaging features of this tumor, especially its enhancement pattern ...

Prenatal diagnosis of abnormal umbilical cord insertion: a rare case of furcate insertion
AbstractFurcate insertion (FI) is an extremely rare abnormality of umbilical cord insertion. One of the complications associated with FI is hemorrhage from the umbilical vein at the site of FI of the umbilical cord, which can cause sudden intrauterine fetal death. Because of its rarity, no prenatal diagnosis of FI has been reported. A 31-year-old woman at 34  weeks’ gestation was referred to us for suspected abnormal cord insertion. Ultrasonography showed normal fetal growth and amniotic fluid volume, with no fetal anomalies. Although the umbilical cord contained three vessels inserted at the center of the place...

Usefulness of three-dimensional transesophageal echocardiography for diagnosis of hemolytic anemia due to inverted internal felt strip after surgery for aortic dissection
AbstractFelt strips are widely used for reinforcement of the aortic stump in surgery for aortic dissection (AD). Postoperative hemolytic anemia (HA) due to an inverted internal felt strip at the aortic stump fixation for AD is extremely rare. A 70-year-old woman underwent ascending aorta replacement for acute type A AD, where both proximal and distal anastomotic sites were reinforced with Teflon felt strips. A week later, macroscopic hematuria and HA emerged. Three-dimensional transesophageal echocardiography (3D-TEE) demonstrated that the proximal inner felt strip turned up and protruded into the aortic inner lumen. At re...

Isolated breast vasculitis manifested as breast edema with suggestive sonographic findings: a case report with imaging findings
We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be se en in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound. (Source: Journal of Medical Ultrasonics)

Diagnosis of Joubert syndrome via ultrasonography
AbstractJoubert syndrome (JS) and related disorders (JSRD) are a group of multiple congenital anomaly syndromes in which the diagnostic hallmark is the molar tooth sign (MTS), a complex midbrain malformation visible on brain imaging. Detection of the MTS should be followed by a diagnostic protocol to assess multi-organ involvement. The incidence of JSRD ranges between 1/80,000 and 1/100,000 live births, although these values may represent an underestimate. The neurological components of JSRD include hypotonia, ataxia, intellectual disability, abnormal eye movements, and neonatal breathing problems. These may be associated ...

The role of endoscopic ultrasound in the diagnosis of gallbladder diseases
AbstractEndoscopic ultrasound (EUS) has recently played an increasing role in the diagnosis of gallbladder diseases. This review aims to summarize the role of EUS in the diagnosis of gallbladder lesions. EUS provides high-resolution images that can improve the diagnosis of gallbladder polypoid lesions and microlithiasis, in addition to evaluating gallbladder thickness and staging of gallbladder carcinoma. Contrast-enhancing agents may be useful for the differential diagnosis of gallbladder lesions, but the evidence of their effectiveness is still limited and further studies are required in this area to establish its useful...

Coexistent borderline serous cystadenoma with multifocal hydatidosis in a young female: lessons learnt
We present a case of a 24-year-old female patient who was diagnosed with multifocal hydatidosis involving the liver and bilateral ovaries on imaging. Postoperative histopathology confirmed the hydatid disease in the liver and one ovary. However, the cystic lesion in the other ovary turned out to be a borderline serous cystadenoma. This case highlights the limitation of imaging in differentiating between simple hydatid cysts and serous cystadenomas of the ovaries. Another point we learnt is that even in the presence of multifocal hydatidosis in endemic regions, serous cystadenoma needs to be considered in imaging differenti...

Cervical elastography during pregnancy: a critical review of current approaches with a focus on controversies and limitations
Abstract In normal pregnancy, the cervix functions as a protective mechanical barrier that must remain tight and closed. Premature remodeling and consecutive shortening occur in many cases of spontaneous preterm birth. Although the complex underlying physiology of normal and abnormal cervical remodeling is not fully understood, it is clear that cervical softening occurs prior to delivery, and inappropriate timing seems to be associated with preterm delivery. Also, degree of cervical softness is a component of the Bishop score currently used clinically to predict successful induction of labor. Therefore, the as...
