Set. 2006 7 3 287-291 JOURNAL OF Veterinary Science Surgical treatment and histopathology of different forms of olecranon and presternal bursitis in cattle and buffalo Ahmed Fathy Khaled Radad2 Department of Animal Surgery and 2Department of Pathology Faculty of Veterinary Medicine Assiut University Assiut 0882 Egypt Thirty seven cases of bursitis presented to our Veterinary Teaching Hospital from 2001 to 2005. There were 10 adult female buffalos with olecranon bursitis one had bilateral bursitis and 26 calves 7 cattle and 19 buffalos 16 males and 10 females with presternal bursitis. There were 10 out of 11 cases of olecranon bursitis and 21 out of 26 cases of presternal bursitis with different forms cystic proliferative and fibrous that were removed surgically. The remaining 6 cases cystic bursitis olecranon 1 presternal 5 were treated by aspiration of their contents and injection of 4 iodine tincture intra-bursally. Only 2 cases recovered 3 cases progressed to fibrosis and required further surgical treatment 2 to 3 weeks later and 1 case continued to have a cystic lesion. Histopathological examination of tissue specimens from different forms of bursitis revealed that the acquired bursae were generally lined with synovial-like membrane formed from 2-3 cellular layers that covered the connective tissue capsule. The connective tissue capsule differed from one type to another and consisted of fibrous tissues containing numerous small blood vessels blood capillaries lymphatics and nerves. There was also evidence for inflammation within the capsule represented by congestion of blood vessels and the presence of perivascular inflammatory cells mostly mononuclear. In conclusion surgical treatment was successfifl and effective for treatment of olecranon and presternal bursitis particularly for the chronic proliferative and fibrous form in cattle and buffalo. The histological structure of the acquired bursae was relatively similar consisting of a synovial-like .
