[Lesion of the cardiac arteries in general miliary tuberculosis]

An exceptionally rare case of isolated involvement of myocardial vessels with tuberculosis without the development of myocarditis is described. Tuberculosis granulomas were located in the adventitium of intra- and extramural ramifications of coronary vessels and along the fibers of interstitial tissue in immediate proximity to the vessels. The media was also affected in some areas by the specific inflammatory process in the form of foci. Uneven proliferation leading to the narrowing of the vessel lumina was observed in the intima. Tuberculous granulomas were found in the adventitium of the descending branch of the left coronary artery. The extention of the tuberculosis process into coronary vessels occurs most likely by the hematogenous route.
