Cross Sectional Imaging

Deviations from the normal process of embryogenesis can result in various developmental anomalies of the superior vena cava (SVC). While these anomalies are often asymptomatic, they assume clinical importance during interventions such as central venous catheterisations and pacemaker implantations and during cardiothoracic surgeries while instituting cardiopulmonary bypass and for creation of cavo-pulmonary connections. Role of imaging in identifying these anomalies is indispensable. Cross-sectional imaging techniques like CT venography and magnetic resonance (MR) venography allow direct visualisation and consequently increased detection of anomalies. CT venography plays an important role in detection of SVC anomalies as it is readily available, has excellent spatial resolution, short acquisition times and potential for reconstruction of images in multiple planes. This pictorial review focuses on the developmental anomalies of the SVC and its tributaries highlighting their embryological basis, imaging appearances on CT venography and potential clinical implications, where relevant.

There is a wide spectrum of congenital anomalies of the superior vena cava, which are more increasingly recognized in cross-sectional imaging. Although some of these anomalies are asymptomatic, others have important clinical and interventional implications. Imaging modalities such as computed tomography and magnetic resonance imaging play an important role in the accurate characterization of these anomalies, which is essential for mapping prior to surgeries or interventions. In this article, we review a wide range of anomalies of the superior vena cava, including the embryological basis, cross-sectional imaging findings, and clinical implications, particularly from an interventional radiology perspective. We also discuss the treatments and complications of these anomalies.

Vena Cava Syndrome

This paper addresses the diagnosis and management of superior vena cava syndrome (SVCS) due to malignant intrathoracic tumours. Diagnosis of SVCS is usually established by bedside examination. Chest X-ray and computed tomography may be helpful, but the cavography remains the “gold-standard”. Other imaging techniques (MRI, nuclear flow studies) are more of scientific interest. Bronchoscopy helps to evaluate the risk of pulmonary complications and endoscopic procedures often lead to histological findings. In the treatment of malignant SVCS surgery, radiotherapy, and chemotherapy have been successfully used. The placement of a vascular stent might be an additional or alternative possibility. There are no conclusive indication criteria and no conclusive regimen concerning post-stenting anticoagulation. From all reported results and published papers we draw the conclusion that the immediate effects of stent implantation and the long-term results of tumour-specific therapy are complementary to one another. The stent dilates the local venous stenosis while tumour-specific therapy has a general effect on the vascular and respiratory situation in a multi-therapy concept.

Contrast Discrimination

Cross-sectional imaging techniques are becoming increasingly important for the evaluation of foot and ankle disorders. Computed tomography affords superior depiction of osseous anatomy, and is useful in the assessment of acute fractures, degenerative joint disease, and postoperative alterations. Magnetic resonance imaging is particularly well suited to soft tissue disease, including neoplasms, tendinitis, myopathy, and infection, owing to its excellent contrast discrimination capabilities.

Pictorial Review

AbstractDespite the decline in mortality rates over the last 20 years, cancer remains one of the leading causes of death in children worldwide. Early recognition and treatment for acute oncological emergencies are vital in preventing mortality and poor outcomes, such as irreversible end-organ damage and a compromised quality of life.Imaging plays a pivotal and adjunctive role to clinical examination, and a high level of interpretative acumen by the radiologist can make the difference between life and death. In contrast to adults, the most accessible cross-sectional imaging tool in children typically involves ultrasound. The excellent soft tissue differentiation allows for careful delineation of malignant masses and along with colour Doppler imaging, thromboses and large haematomas can be easily identified. Neurological imaging, particularly in older children is an exception. Here, computed tomography (CT) is required for acute intracranial pathologies, with magnetic resonance imaging (MRI) providing more definitive results later.This review is divided into a ‘body systems’ format covering a range of pathologies including neurological complications (brainstem herniation, hydrocephalus, spinal cord compression), thoracic complications (airway obstruction, superior vena cava syndrome, cardiac tamponade), intra-abdominal complications (bowel obstruction and perforation, hydronephrosis, abdominal compartment syndrome) and haematological-related emergencies (thrombosis, infection, massive haemorrhage). Within each subsection, we highlight pertinent clinical and imaging considerations.The overall objective of this pictorial review is to illustrate how primary childhood malignancies may present with life-threatening complications, and emphasise the need for imminent patient management.

Infertility is a common problem. The role of imaging in assisting clinical evaluation is discussed. Ultrasound and magnetic resonance imaging are first-line, noninvasive imaging techniques that provide accurate definition of anatomical causes of infertility. This affords an opportunity to deliver timely and appropriate treatment. This pictorial review illustrates normal imaging anatomy and various causes of male infertility, and focuses on congenital and acquired testicular abnormalities and post-testicular obstruction, such as congenital absence of the vasa deferentia, seminal vesicle cysts, prostatic utricle cysts, Mullerian cysts, ejaculatory duct cysts (Wolffian cysts), and epididymal obstruction.
