These ueomorphic structiires occupy aPosition corresponding to the course of the intercostal nerves in theintercostal Spaces iinderneath the pleura. They are conspiciious,therefore, when they occnr in large numbers, for their regulärarrangement. False neuromata of the intercostal nerves in their early stagesroay be confused with tuberculosis and in their later stages withechinococci. At first they form gray, firm tubercles varying in sizefrom a hemp seed to a pea and surrouuding the nerve like a ring(Fig. 81). In the large tubercles—they sometimes reach the size of Fig. False neuroma of the intercostal nerves in cattle. a potato—the myxomatous tissue is more couspicuous. In thismanner structures arise which, to the naked eye, possess greatresemblance to echinococci. Section, however, immediately demon-strates to the inspector the triie nature of the alteration, for onlya slight quantity of slime-like tissue and no fluid oozes fromthe spherical or elongated structures. Myxo-fibroma of theintercostal nerves is distinguished by the complete absence of«aseation. False neuromata of the intercostal nerves are but rarelyobserved in slaughtered cattle. Moreover, they exercise no influ-ence over the character of the meat. It is necessary merely toxemove them and this may be done in connectiou with the nerveStrands.
