Granulomatous infections can cause multiple echogenic foci in which organs?

Granulomatous infections can cause multiple echogenic foci in which organs?

• A. Lungs and kidneys
• B. Brain and liver
• C. Liver and spleen
• D. Heart and liver

Answer: (C)

Granulomatous infections often form granulomas that can later calcify. When these calcified granulomas are present, they show up on ultrasound as multiple bright spots—echogenic foci—with possible shadowing. The liver and spleen are especially susceptible because they are part of the reticuloendothelial system and filter infections, so granulomatous inflammation frequently localizes there and can calcify over time. That combination—systemic granulomatous disease plus calcified nodules in the liver and spleen—produces the pattern of multiple echogenic foci most classically seen in those organs. Other sites can be involved in some diseases, but liver and spleen are the typical abdomen-related findings for this scenario.
