RESUMO
A healthy 20-year-old male presented with aborted sudden death. Both thoracic echocardiography and cardiac computed tomographic angiography demonstrated the characteristic findings of ALCAPA noting a dilated and tortuous right coronary artery, dilated coronary collateral arteries within the interventricular septum or along the surface of the heart, and visualization of the left coronary artery origin from the posterior aspect of the main pulmonary artery. Both imaging modalities demonstrated all three characteristic findings of this rare coronary anomaly and served as complementary imaging studies for surgical correction.

About 1,700 children in the United States are diagnosed yearly with lymphomas; Hodgkin's disease accounts for approximately half of these cases, or 6% of all childhood cancers. Contemporary therapy allows for the achievement of remission in the majority of cases. The fusion of positron emission tomography (PET) with CT provides the most accurate imaging method for disease characterization and treatment response. However, experience with 18F-FDG PET-CT is limited in pediatric Hodgkin's disease. Numerous non-oncologic processes can mimic recurrent or residual tumor. This pictorial addresses mimickers of disease such as uptake in normal structures, infections, transforming germinal canters and effects of therapy on normal tissues. It is essential for radiologists to be familiar with these findings in order to stage disease activity and therapeutic response accurately.
