Examination by means of the speculum is of great val m diagnosing such lesions. On examining the parts through the rectum, the walls of the uterus are found to be greatly thickened, sometimes^ mdurated, bosselated or totally deformed. The Fallopian tubes and ovaries may have attained enormous dimensions, and the normal anatomy of the parts is greatly altered both as regards dimensions and relations. The almost inevitable consequences of tuberculosis of the genital organs are hypertrophy, induration or caseation of the subsacral and sublumbar lym- phatic glands. Udder. — Tuber- culosis of the udder may be primary or secondaiy. W hen the infection is slight the results may es- cape notice for weeks or even months, the patients appearing to suffer only from sub-acute or chronic mammitis, while at the same time the milk preserves its ordinary appearance. In time, however, the mammitis be- comes aggravated, the infected regions are enlarged, and the secretion becomes grumous, serous, curdled, and of a yellowish colour, after- wards ceasing altogether. In some cases one quarter only is attacked, though total mammitis is more common. These forms of tuberculous mammitis tend towards hypertrophy, local hardening, and the formation of deeply-seated cavities contain- ing pus, the gland itself sometimes acquiring enormous dimensions. The retro-mammary lymphatic glands are invaded even before the gland itself is seriously attacked. For a longer or shorter time the udder may externally appear healthy, although on manual examina- tion these lymphatic glands are found to be indurated and Fig. 279.—Hj'pertrophio tuberculous mammitis.
