Rickettsial infection occurs, causing focal or disseminated vasculitis (4) and perivasculitis with significant vascular leakage and end-organ injury to lung, heart, liver, spleen and central nervous system, thus explaining the various unexpected clinical manifestations.
The exact cause of tractional retinal detachment remains uncertain but perivasculitis may be possible explanation.
Thus far, no evidence indicates that the animals testing positive for the enteric CoV showed clinical disease that pointed to pyogranulomatous inflammation, necrosis with or without perivasculitis, and vasculitis in abdominal and visceral organs associated with the systemic variant.
Due to persistent microhematuria, cystoscopy was performed and revealed very small papillary lesions in the bladder and biopsy showed focal vasculitis and perivasculitis of a small artery of the lamina with no evidence of malignancy (Figure 1).
Eales' disease is an idiopathic disease with retinal perivasculitis predominantly affecting the peripheral retina during the inflammatory stage followed by sclerosis of the retinal veins and retinal ischaemia and finally, retinal or optic disk neovascularization, recurrent haemorrhages, with or without retinal detachment (1).
We particularly noted lesions in the central system of moose that were characterized by nonpurulent meningo-encephalitis, edema, perivasculitis in extracellular spaces, and focal ischaemic necrosis because of thrombosis of small vessels.

Although splenic lesions of Churg-Strauss syndrome have been described and consist of extravascular granulomas, eosinophilic abscess, and perivasculitis,[9] similar findings in the lymph nodes have not been likewise documented.
Histologic findings in the juvenile alligators were multiorgan necrosis, heterophilic granulomas, and heterophilic perivasculitis and were most indicative of septicemia or bacteremia.
