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.

Abstract In the appropriate clinical setting, certain aspects of extranodal abdominal lymphoma, as revealed by current cross-sectional imaging techniques, should be considered potentially diagnostic and can hasten the diagnosis. In addition, diagnostic imaging in the context of biopsy-proven lymphoma can accurately stage the disease for its appropriate treatment. The purpose of this article was to illustrate the various imaging aspects of extranodal lymphoma in the abdomen.

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.

AbstractPersistence of the embryonic “fifth aortic arch” in postnatal life is a rare, enigmatic – and at times controversial – condition, with variable anatomical forms and physiological consequences. First described in humans over 40 years ago by Van Praagh, the condition was labelled the “great pretender” by Gerlis 25 years later, because of its apparent propensity to mimic anatomically similar structures. Despite many subsequent case reports citing the condition, the true developmental origin of these structures remains unresolved, and has been the subject of debate among embryologists for more than a century. A persistent fifth aortic arch has been defined as an extrapericardial structure, arising from the ascending aorta opposite or proximal to the brachiocephalic artery, and terminating in the dorsal aorta or pulmonary arteries via a persistently patent arterial duct. This description may therefore encompass various anatomical forms, such as a unilateral double-lumen aortic arch, an unrestrictive aortopulmonary shunt, or a critical vascular channel for either the systemic or pulmonary circulation. The physiological properties of these vessels, such as their response to prostaglandins, may also be unpredictable. In this article, we demonstrate a number of cases that fulfil the contemporary definition of “persistent fifth aortic arch” while acknowledging the embryological controversies associated with this term. We also outline the key diagnostic features, particularly with respect to the use of new cross-sectional imaging techniques.

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.

Skull base lesions can be related to wide number of pathologies including infections, benign and malignant tumors. Accurate diagnosis and differentiation between these entities is important for prompt and appropriate treatment. However, computed tomography and routine magnetic resonance imaging techniques only provide information on the extent of the lesions, with limited ability to differentiate between benign and malignant lesions. Diffusion-weighted imaging can help in many such situations by providing additional information, including help in differentiating benign from malignant lesions, so that appropriate treatment can be initiated. In this review article, we illustrate the imaging findings of the spectrum of skull base lesions, emphasizing the role of diffusion-weighted imaging in this domain.

Hip pain can have multiple causes, including intra-articular, juxta-articular, and referred pain, mainly from spine or sacroiliac joints. In this review, we discuss the causes of intra-articular hip pain from childhood to adulthood and the role of the appropriate imaging techniques according to clinical suspicion and age of the patient. Stress is put on the findings of radiographs, currently considered the first imaging technique, not only in older people with degenerative disease but also in young people without osteoarthritis. In this case plain radiography allows categorization of the hip as normal or dysplastic or with impingement signs, pincer, cam, or a combination of both.

Periaortic air can be seen in various conditions which can be a benign imaging finding or harbinger of a catastrophic event. The causes vary in native aorta and post-operative aorta. A radiologist has an important part in the management process of these patients, as the treatment varies from conservative to radical surgery based on the aetiology. The presence of periaortic air seen in the light of various clinical, laboratory and radiological findings can guide the radiologist towards a particular aetiology. Cross-sectional imaging, mainly computed tomography, is an indispensable tool in recognising ectopic periaortic air and to identify the associated findings and eventually make an accurate diagnosis. We present a pictorial review of various causes of the periaortic air in native and postoperative aorta, the salient features and management of the described conditions.
