The Extended Fetal Cardiac Examination: Is It Feasible in a High-Risk Practice?

The aims of this study were to demonstrate the feasibility of obtaining additional cardiac views as proposed on an extended fetal cardiac examination and to see if there was any variation in individual components of that examination stratified by sonographer training, patient body habitus, or equipment. We retrospectively reviewed 200 consecutive detailed second-trimester high-risk fetal obstetric sonograms that included additional extended cardiac views. We analyzed the percentage of the time individual views were obtained, with variation based on (1) a sonographer with greater than 3 years of training compared with a group with 6 to 12 months of training, (2) 2 different ultrasound units, and (3) different body mass indices.

Intra-renal splenosis mimicking a solid renal mass.

We present the case of a young woman found to have an exophytic solid renal mass who was referred to our institution for ablation of said mass versus partial nephrectomy. The patient had a history of splenectomy. Ultrasound demonstrated a homogeneous solid left renal mass, and the diagnosis of intra-renal splenosis was considered based on the patient's history.

Fetal ultrasound: Early diagnosis and natural evolution of proximal femoral focal deficiency.

Proximal femoral focal deficiency is an extremely rare congenital anomaly with only a few case reports in the literature. This case illustrates one diagnosed by prenatal ultrasound. The diagnosis may be isolated or associated with other abnormalities and syndromes.

A reminder of peristalsis as a useful tool in the prenatal differential diagnosis of abdominal cystic masses.

With routine antenatal ultrasound and recent advances in ultrasound technology, fetal intraabdominal cystic masses are recognized more often and are better characterized than in the past. They may be classified as solid and cystic, and may originate from multiple structures. When considering the extensive differential diagnosis of cystic masses, the observation of peristalsis narrows the possibilities to the gastrointestinal tract.

Renal Cell Carcinomas: Sonographic Appearance Depending on Size and Histologic Type.

Objectives: Prior studies have demonstrated that approximately 10% of malignant renal cell carcinomas are as echogenic as angiomyolipomas on sonography. However, a recent presentation suggested that small (<1-cm) echogenic renal masses are always angiomyolipomas or other benign entities. We therefore examined our own cases of renal cell carcinoma, with corresponding sonography, to confirm that some renal cell carcinomas may also be detected as hyperechoic masses on sonography.
