Lateral cervical sinus: specific sonographic findings in two pediatric cases
We report two pediatric cases with lateral cervical sinus, and pathognomonic sonographic findings to confirm the diagnosis. The first case involved a 3-month-old boy with a sinus on the lateral neck and occasional drainage from a cervical sinus opening. Sonography revealed that the sinus tract extended between the external and internal carotid arteries. In case two, a 1-month-old girl presented with a sinus on the lateral neck and signs of acute infection at the site of a pinpoint opening. Sonography revealed an oval-shaped cystic lesion and sinus tract extending between the external and internal carotid arteries. Sonograp...

Utility of three-dimensional transesophageal echocardiography for diagnosis of unroofed coronary sinus
We report a case of unroofed coronary sinus (URCS) in a 42-year-old female. At an outpatient clinic, she was found to have an atrioventricular septal defect and mitral regurgitation with pulmonary hypertension, and she was transferred to our institute for surgical treatment. Both atrioventricular valves were located at the same level, and both the right atrium (RA) and right ventricle were enlarged on two-dimensional transthoracic echocardiography. Color Doppler imaging demonstrated severe mitral and tricuspid regurgitation and a left-to-right shunt from the left atrium (LA) to the RA. Although an ostium primum defect of t...

Prenatal diagnosis and postnatal outcome of persistent right ductus arteriosus: a report of three cases
Abstract The ductus arteriosus is a fetal vascular connection between the main pulmonary artery and aorta that diverts blood away from the pulmonary bed. Left and right ductus arteriosi emerge from embryological aortic arches. In normal embryologic cardiac development, both right aortic and ductal arches regress and the left ones persist. Persistent right ductus arteriosus (rDA) is one of the congenital anomalies of the ductal arch. In this paper, we report three cases of persistent right ductus arteriosus with right aortic arch.

A case of fetal osteogenesis imperfecta type 2A: longitudinal observation of natural course in utero and pitfalls for prenatal ultrasound diagnosis
We present a case of osteogenesis imperfecta (OI) type 2A in which a natural course in utero was observed from 23 weeks’ gestation to term. At 23 weeks’ gestation, a sonographic examination showed a cloverleaf skull-like head, a narrow thorax, and marked shortening of the long bones with bowing of the femurs and humeri. Follow-up examinations showed that the cloverleaf skull-like head was not evident at 28 weeks’ gestation. Discontinuity of the ribs and femurs was observed at 26 and 30 weeks’ gestation, respectively. This finding suggested bone fractures, which were confirmed by ...

Ultrasound in diagnosis of intrascrotal metastasis of Wilms’ tumor: first case report of a Chinese boy and review of the literature
Abstract A 31-month-old boy with Wilms’ tumor (WT), which primarily had originated from the left kidney, was treated with nephrectomy and adjuvant chemotherapy. 2 months after nephrectomy, a left scrotal mass was found at routine follow-up. High-frequency sonography examination revealed an enlarged left testis with a heterogeneous texture and a hypoechoic solid mass in the left scrotum. Moreover, hypervascular signals presented in both the left testis and the mass on color Doppler flow imaging. Left orchiectomy was performed for suspected intrascrotal metastasis of WT, which was confirmed by histopathol...

Five neonatal cases of pyriform sinus fistula with cervical cystic lesion: a comparison between sonography and other modalities
We describe five neonatal patients with pyriform sinus fistula-appearing cervical cystic lesions. All patients were examined by sonography; of these, three patients were also examined by barium esophagography, two by CT, and one by MRI. The fistula was detected by sonography but not CT in one patient and by barium esophagography but not MRI in one. Two patients whose fistulas were detected by sonography had an oval-shaped and relatively small cystic lesion. One patient whose fistula could be detected only by barium esophagography had a relatively large cystic lesion. In two patients, whose fistulas were not detected by son...

Abstract Pulmonary alveolar microlithiasis (PAM) is a rare disorder of unknown etiology affecting people at any age. It is characterized by multiple and microscopic calcium deposits diffusely localized within the alveoli. Thorax high-resolution computed tomography is considered the gold standard for PAM imaging. Herein we report for the first time the use of trans-thoracic ultrasound (TUS) examination in a young severely obese PAM female patient, diagnosed at the age of 10, and referred to our clinic for re-staging purposes at the age of 36. Unlike expected, no reverberation or additional artifacts were appreciate...

Fetal diastematomyelia associated with vertebral malformation: ultrasound, MRI, and pathomorphological findings
Abstract Using a specific clinical example, we demonstrate the ability of prenatal magnetic resonance imaging (MRI) to diagnose associated spine and spinal cord malformations in the group of spinal dysraphisms. Thus, the original ultrasound (US) and MRI results for the affected fetus at week 21 are illustrated and described in detail. The paucity of reports of prenatal MR-semiotic findings of split cord malformation comparing US and pathomorphological findings at a relatively early gestational age makes the present case unique and instructive. The outstanding capability of MRI to diagnose spinal pathologies indica...

Incomplete excision or postoperative hematoma: primary right ventricular intramyocardial lipoma involving the right ventricular outflow tract
We presented a case of primary intramyocardial lipoma involving the right ventricular outflow tract diagnosed through transthoracic echocardiography and surgical pathology. The tumor was completely resected. Surprisingly, an echogenic mass similar to the one seen before the operation in terms of the echogenicity and morphological characteristics was found at the same location 1 week after the complete resection. Was it an incomplete excision or a postoperative hematoma? After regular echocardiographic follow-up, the echogenic mass disappeared. It was inferred that the echogenic mass may have been a postoperative intra...

The lobar approach to breast ultrasound imaging and surgery
Abstract Breast cancer is a lobar disease in the sense that, at the earliest stages, the cancer is structurally confined to a single sick lobe. The subgross morphology of breast carcinoma is often complex, as multiple invasive foci are frequently present and the ductal system often contains an extensive in situ component. Adequate preoperative visualization of all of the malignant structures within the affected breast and preoperative mapping of the lesions in relation to the surrounding normal structures are essential for successful image-guided breast surgery and therefore are key factors in assuring adequate lo...

A case of a pancreatic tumor that was diagnosed as metastasis from lung cancer by endoscopic ultrasound-guided fine needle aspiration
Abstract Metastatic tumors are rare in the pancreas, and some cases are difficult to distinguish from pancreatic cancer. However, distinguishing between them is very important to formulate a treatment plan. A case of a rare disease, called overlap cancer, involving metastatic tumors to the pancreas and right kidney from lung cancer, and duodenal papilla cancer, is described. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for diagnosing metastatic pancreatic tumors, particularly in patients with multiple cancers.

We report a juvenile patient presenting with recurrent ischemic stroke caused by BHS, which was revealed by carotid duplex ultrasonography. Carotid duplex ultrasonography performed in the neutral position showed normal findings. However, disappearance of end-diastolic blood flow of contralateral VAs was observed with head rotation. Digital subtraction angiography confirmed occlusion at C1/2 levels in the VA contralateral to the head rotation, bilaterally. Importantly, our patient did not recognize the association of head rotation and previous episodes of stroke. We suggest that BHS should be considered in patients with cry...
