Expanding upon the unilateral hyperlucent hemithorax in children.

Unilateral hyperlucent hemithorax is a common pediatric chest radiographic finding that may also be seen at computed tomography. It may result from congenital or acquired conditions involving the pulmonary parenchyma, airway, pulmonary vasculature, pleural space, and chest wall, as well as from technical factors such as patient rotation. Unilateral hyperlucent hemithorax has a broad differential diagnosis that includes unilateral emphysematous or bullous disease, pneumatocele, foreign body aspiration, Swyer-James syndrome, congenital lobar emphysema, endobronchial mass, unilateral pulmonary agenesis, proximal interruption of the pulmonary artery, scimitar syndrome, diaphragmatic hernia, and Poland syndrome.

Imaging of pulmonary venous developmental anomalies.

Objective: The purpose of this article is to review pulmonary venous embryology and to present the imaging findings of a variety of pulmonary venous developmental anomalies, including total anomalous pulmonary venous connection, partial anomalous pulmonary venous connection, pulmonary vein stenosis and hypoplasia/atresia, and cor triatriatum.

Conclusion: There are numerous developmental pulmonary venous anomalies. Although these conditions have traditionally been evaluated with echocardiography and angiography, they can be accurately diagnosed using both MRI and MDCT.

Interrupted aortic arch: spectrum of MRI findings.

Objective: The objective of this article is to review the types, pathogenesis, MRI appearance, treatment, and prognosis of interrupted aortic arch (IAA).

Conclusion: IAA is a rare congenital vascular anomaly. Although this entity has been evaluated traditionally with echocardiography and angiography, MRI can accurately diagnose and characterize the various forms of IAA and associated congenital heart defects.

Evaluation of imaging-guided core biopsy of pelvic masses.

Objective: The purpose of this study was to evaluate the accuracy and complications of imaging-guided core biopsy in the diagnosis of pelvic masses.

Conclusion: Imaging-guided core biopsy of pelvic masses is accurate and safe. The accuracy and sensitivity of biopsy under sonographic guidance are higher than those of CT-guided biopsy, although the difference is not statistically significant.

Bilateral giant abdominoscrotal hydroceles complicated by appendicitis.

Abdominoscrotal hydrocele is a rare entity, with fewer than 100 cases reported in children. Bilateral abdominoscrotal hydroceles are even less common, with 14 cases reported in children. Various complications of abdominoscrotal hydrocele have been reported in the literature.
