Focal renal lesions in the background of chronic kidney disease (CKD) present a diagnostic challenge. Contrast administration is usually avoided in such a setting, undermining the usefulness of computed tomography and magnetic resonance imaging. Focal regenerating nodules may occur in the background of CKD and closely mimic renal neoplasms. The aim of the present article was to highlight the salient manifestations of such CKD pseudotumors on different imaging modalities and also to depict the differentiating features from malignancy. Radiologists must be aware of the imaging appearance of this uncommonly talked about entity so as to avoid inadvertent surgery or cause undue anxiety to the patient.

Inflammatory myofibroblastic tumors (IMT) are a benign tumor entity, which rarely develop in the liver. Surgery is the most common treatment for these lesions as it is difficult to distinguish them from malignant liver tumors and local recurrent growth may occur. IMT is a diagnostic challenge for imaging. Only a limited number of reports of single cases or small number of patients described the imaging features on computed tomography. Reports on IMT appearance on magnetic resonance imaging are scarce. We present a case of IMT of the liver with infiltration of the abdominal wall treated with surgery and describe the imaging features with the use of the hepatobiliary contrast agent, gadoxetic acid (Gd-EOB).

Renal angiomyoadenomatous tumour is a rare, recently describedneoplasm with a distinctive histological appearance. Althoughreported in the pathology literature, to our knowledge, no priorreports have described its imaging appearance. We describe thecomputed tomography and magnetic resonance imaging featuresof an incidentally detected renal angiomyoadenomatous tumourthat appeared as a well-marginated, solid T2-hypointense enhancing mass, in a 50-year-old woman. It is indistinguishable from a variety of benign and malignant renal neoplasms.

This review explores the classification and evaluation of suspicious renal lesions across several radiologic imaging modalities. Diagnostic medical sonography (DMS), computed tomography (CT), magnetic resonance imaging (MRI), and contrast-enhanced ultrasound (CEUS) are the primary modalities used to investigate questionable lesions found within the kidneys. Renal masses may range from completely benign to malignant. They are classified based on many different features and characteristics. These lesions may be simple cystic, complex cystic, or solid in nature. Masses may also exhibit varying degrees of vascularity, septations, and calcifications. The discussed imaging modalities have varying strengths, limitations, and implications for use. Imaging techniques may be used independently or in conjunction to best diagnose and treat a patient with a suspicious renal mass. The aim of this review was to describe the diagnostic value of the imaging modalities (DMS, CT, MRI, and CEUS) and their role in the evaluation of suspicious renal lesions.

The authors presented the computed tomography and magnetic resonance imaging appearances of a painful os cuboideum secundarium. To the authors' knowledge, this is the first report of the cross-sectional imaging appearance of this condition, and serves to underline the utility of computed tomography and magnetic resonance imaging in the investigation of foot pain.

Stroke is the third most common cause of death in the developed world and the leading cause of adult disability. The goals of an imaging evaluation for acute stroke when presented with patients with raised clinical suspicion of an acute stroke are to obtain accurate information about the momentary state of brain tissue. A comprehensive evaluation is best achieved with a combination of computed tomography or magnetic resonance imaging technique. Unenhanced computed tomography and magnetic resonance imaging can help rule out hemorrhage and identify early morphologic signs of acute brain ischemia. Computed tomography and magnetic resonance perfusion imaging and magnetic resonance diffusion weight imaging, can help depict unsalvageable ischemic brain tissue and the area of penumbra. Computed tomography angiography and magnetic resonance angiography are widely used techniques for assessment of both, the intracranial and neck circulation.
