This case was originally posted as an unknown.\u00a0 The consensus of folk who got back to me is that this is an uncommon degenerative process in a microinfarction where the mitochondria calcify, leading to the appearance of multiple faint blue dots in an area of myocyte necrosis.\u00a0 Apparently it is more commonly seen in microinfarctions associated with catecholamines (e.g. stress cardiomyopathy, ingestion of sympathomimetics such as methamphetamine).<\/p>\n
This is the case of a teenager found dead in bed in the morning.\u00a0 He had been complaining of a URI the evening before.\u00a0 At autopsy, he doesn’t have much going on.\u00a0 A little pulmonary edema R&L lungs 710 and 530 grams),\u00a0 \u00a0The heart was a little big at 430 grams with mild LV dilation.\u00a0 Tox is negative. Viral culture positive for rhinovirus.\u00a0 Bacterial cultures were taken at three locations (first hospital, referral hospital, ME office).\u00a0 All three were positive, but all three grew multiple different organisms, with no overlap between labs.<\/p>\n
At autopsy, he had one odd finding — these areas in the myocardium.\u00a0 I usually take 8 sections of heart (posterior lv, lateral lv, anterior lv, ivs, rv, avn, san x2).\u00a0 These areas were sparsely found in all of the LV sections.<\/p>\n
