This pictorial essay aims to present various lesions that could present as consolidations with diffuse of focal high attenuation on computed tomography, helping to make the diagnosis more confident and specific. The radiologic literature has limited information about such findings and the role of computed tomography in the differential diagnosis. The following diseases are presented: metastatic pulmonary calcification, pulmonary alveolar microlithiasis, amiodarone lung, talcosis, iodinated oil embolism, tuberculosis, silicoproteinosis, and amyloidosis. In conclusion, air-space consolidations can be seen in a wide variety of diseases affecting the lungs. The identification of the different patterns of consolidation with focal high attenuation narrows the differential diagnosis. We present a diagnostic approach based on appearance and distribution of these lesions.

Objective: To evaluate the main technical limitations of automated breast ultrasound and to determine the proportion of examinations excluded. Materials and Methods: We evaluated 440 automated breast ultrasound examinations performed, over a 12-month period, by technicians using an established protocol. Results: In five cases (1.1%), the examination was deemed unacceptable for diagnostic purposes, those examinations therefore being excluded. Conclusion: Automated breast ultrasound is expected to overcome some of the major limitations of conventional ultrasound in breast cancer screening. In Brazil, this new method can be accepted for inclusion in routine clinical practice only after its advantages have been validated in the national context.

Liposarcomas are the most common soft tissue sarcoma of adults, and primary mediastinal liposarcomas are rare. We present a case of a 50-year-old man with primary mediastinal liposarcoma without any invasion into the surrounding structures, such as the esophagus, trachea, or left atrium of the heart. Following surgical removal of the liposarcoma, the patient has had no recurrence after one year. Surgical removal is the treatment of choice for a mediastinal liposarcoma; however, careful long-term follow-up is necessary because the recurrence rate is very high.
