case_images: CT scan without contrast enhancement showing a left anterior low-attenuation (-80 HU) pericardial mass with high attenuation strands surrounded by an irregular capsule (arrow) and a small pleural effusion (arrowhead).

case_images: Nonenhanced computed tomography (CT) of the chest (Figure 1) showed a left anterior low-attenuation (-80 HU) pericardial mass with high attenuation strands measuring 47 mm in diameter, surrounded by an irregular capsule (arrow), and with an associated small pleural effusion (arrowhead).
case_images: Coronal reformatted CT showing no connection between the pericardial mass and infradiaphragmatic fatty tissues.

case_images: CT confirmed no connection with infradiaphragmatic tissues (Figure 2). Contrast-enhanced CT (Figure 3) ruled out pulmonary embolism and aortic dissection but confirmed the typical appearance of pericardial fat necrosis.
case_images: Contrast-enhanced CT showing that the central fatty attenuation of the mass is not enhanced (star); the capsule shows a 50 HU increase in density (arrow).

case_images: CT confirmed no connection with infradiaphragmatic tissues (Figure 2). Contrast-enhanced CT (Figure 3) ruled out pulmonary embolism and aortic dissection but confirmed the typical appearance of pericardial fat necrosis.
case_images: CT scan after 3 months showing a significant reduction in the size of the mass (arrow).

case_images: On follow-up CT after 3 months (Figure 4), the mass was still present but significantly reduced in size (28 mm) (arrow).
