Heart Scan Curiosities #8: Fat heart 8. July 2007 William Davis (2) Here's a curious incidental finding on a heart scan: an unusual fat accumulation around the heart. The arrows point to an unusually large accumulation of fat tissue on either side of the heart. This man was mildly but not excessively overweight at 5 ft 10 inches and 201 lbs. I know of no specific implications of this curiosity. It makes me wonder if he was very obese at one time and has since lost the weight.
