Neurocysticercosis, caused by the larvae of Taenia solium, is the parasitic infection that most commonly involves the central nervous system in humans. Neurocysticercosis is endemic in practically all developing countries, and owing to globalization and immigration it is becoming more common in developed countries like those in western Europe. ⋯ The imaging findings depend on the larval stage of Taenia solium, on the number and location of the parasites (parenchymal, subarachnoid, or intraventricular), as well as on the host's immune response (edema, gliosis, arachnoiditis) and on the development of secondary lesions (arteritis, infarcts, or hydrocephalus). The diagnosis of this parasitosis must be established on the basis of the clinical and radiological findings, especially in the appropriate epidemiological context, with the help of serological tests.

The main objective of this work is to study usefulness of ultrasound (US) for the emergency diagnosis of the penile fracture. ⋯ We believe that US is a useful procedure in the diagnosis of acute penile fracture and that it could be proposed as the diagnostic method of choice to confirm the clinical suspicion of penile fracture. Identifying the exact site of a tear in the tunica albuginea facilitates the surgical procedure.

Connective tissue diseases are often associated with lung diseases that lead to high morbidity and mortality, including interstitial disease, airway disease, pleural lesions, and vascular disease. High resolution CT has high sensitivity for detecting parenchymal disease and potentially reversible lesions, helping to guide treatment. This article emphasizes interstitial pneumonia in association with connective tissue disease and the characteristics that differentiate this entity from idiopathic types. Likewise, we review the most common pulmonary manifestations of each connective tissue disease with the aim of providing the radiologist with a practical approach to the diagnosis and management of these diseases in daily clinical practice.

To determine the most common clinical indications for different diagnostic neuroimaging tests. To analyze the diagnostic yield for each type of test in function of its clinical indication. To quantify the number of additional imaging tests generated as a consequence of pathological findings on the initial study or of the physician's requesting an inappropriate study. ⋯ Most neuroimaging studies are performed for especially prevalent clinical indications; however, in many cases the degree of concordance between the clinical and radiological diagnosis shows there is much room for improvement.
