Cranial pleurisy can be attributed to pathological processes in this area which are likely related to M. hyo and other respiratory pathogens such as SIV, Pasteurella multocida and other bacteria. This cranial pleurisy should be recorded separately from the dorso-caudal pleurisy to allow the appropriate differential diagnosis. These lesions include pleurisy on the surface of the lung lobes or between lobes as interlobar pleurisy.
Pleurisy in the apical and cardiac lung lobes are scored as follows:
- Score 0: No pleurisy in apical and cardiac lung lobes
- Score 1: Pleurisy in apical and cardiac lung lobes
