Computed tomography findings in septic pulmonary embolism: A case report and literature review.

This case report describes the findings of septic pulmonary embolism (SPE) in a young adult male with a history of intravenous drug use who initially presented with signs and symptoms of acute sepsis. The patient underwent evaluation by computed tomography (CT) imaging as well as blood cultures and echocardiography, which confirmed the diagnosis of SPE secondary to Staphylococcus aureus positive bacterial endocarditis. In this case report, we discuss the presentation and characteristic CT imaging findings of SPE as well as highlight the value of this imaging modality in the timely diagnosis and management of this urgent condition.

A Concise Review of the Multimodality Imaging Features of Renal Cell Carcinoma.

The evaluation of renal cell carcinoma (RCC) is routinely performed using the multimodality imaging approach, including ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). Ultrasonography is the most frequently used imaging modality for the initial diagnosis of renal masses. The modality of choice for the characterization of the renal mass is multiphasic CT. Recent advances in CT technology have led to its widespread use as a powerful tool for preoperative planning, reducing the need for catheter angiography for the evaluation of vascular invasion. CT is also the standard imaging modality for staging and follow-up. MRI serves as a problem-solving tool in selected cases of undefined renal lesions. Newer MRI techniques, such as arterial spin labeling and diffusion-weighted imaging, have the potential to characterize renal lesions without contrast media, but these techniques warrant further investigation. PET may be a useful tool for evaluating patients with suspected metastatic disease, but it has modest sensitivity in the diagnosis and staging of RCC. The newer radiotracers may increase the accuracy of PET for RCC diagnosis and staging. In summary, the main imaging modality used for the characterization, staging, and surveillance of RCC is multiphasic CT. Other imaging modalities, such as MRI and PET, are used for selected indications.
