A Case of Metastatic Chromophobe Renal Cell Carcinoma Masked as Suspected Hepatic Abscesses.

Background: Characterizing multiple hepatic lesions on cross-sectional imaging, particularly differentiating abscesses from metastatic lesions, can be challenging.

Case Presentation: A male aged 53 years with a history of chromophobe renal cell carcinoma presented with fevers and abdominal pain and was found to have multiple hepatic lesions concerning for hepatic abscesses. The lesions initially evaded diagnosis on imaging, laboratory tests, and biopsy, but ultimately were determined to be a rare case of metastatic chromophobe renal cell carcinoma of the liver.

Cardiac Neoplasms: Radiologic-Pathologic Correlation.

Cardiac neoplasms are a diagnostic challenge on many levels. They are rare, their clinical presentation may mimic other much more common cardiac diseases, and they are at an uncommon intersection of oncologic and cardiac imaging. The pathology of primary cardiac neoplasms explains their varied imaging features, for example, calcification in primary cardiac osteosarcomas and T2 hyperintensity in myxomas.

Primary Lung Tumors in Children: Radiologic-Pathologic Correlation From the Radiologic Pathology Archives.

Primary lung tumors in children are rare, with a narrow range of diagnostic considerations. However, the overlapping imaging appearances of these tumors necessitate attention to key discriminating imaging and pathologic features. In the neonate and infant, the important considerations include pleuropulmonary blastoma (PPB), infantile fibrosarcoma, and fetal lung interstitial tumor.

Renal Tumors of Childhood: Radiologic-Pathologic Correlation Part 2. The 2nd Decade: From the Radiologic Pathology Archives.

Malignant renal tumors account for 7% of childhood cancers, and Wilms tumors are by far the most common-but not in older children and adolescents. Among individuals in the latter half of their 2nd decade of life, renal cell carcinoma (RCC) is more common than Wilms tumor. The histopathologic spectrum of RCCs in children differs from that in adults.
