RESUMO
Mycobacterium avium infection was diagnosed in an adult cat showing acute lameness of the right hind limb, enlargement of the right popliteal lymph node and two cutaneous nodular lesions of the right chest wall. Conventional radiography of the proximal tibia showed a proliferative osteolytic lesion. Cytological examination of the right popliteal lymph node and the nodular skin lesions fine needle aspiration smears, demonstrated granulomatous inflammation with many negative staining bacilli within macrophages or in smears background. The diagnosis was confirmed by ZiehlNeelsen staining of the smears and the identification of mycobacteria was performed by microbiological and molecular methods. Histopathology performed after the necropsy revealed disseminated mycobacteriosis with granulomatous mesenteric lymphadenitis, granulomatous pneumonia, hepatitis and tibial osteomyelitis. M. avium is a wellknown agent of gastroenteric, respiratory or disseminated disease in immunocompromised cats but there are few cases reported in literature of bone involvement in systemic mycobacteriosis.

This report presents three cases of mycobacteriosis in gang gang cockatoos (Callocephalon fimbriatum) that highlight the potential variation in clinical presentation of this important avian disease. The first case was a female gang gang cockatoo with widespread skeletal disease that presented with a chronic history of weight loss and nonpainful, bilaterally symmetric, distal-wing and leg nodular swellings. The second case was a mature female in good muscle condition with a nodular granulomatous pericarditis and myocarditis causing severe hydropericardium and cardiac tamponade; it was presented for respiratory distress. The third case was one of alimentary mycobacteriosis that presented with a chronic history of weight loss. Some difficulties associated with confirming a premortem diagnosis of mycobacteriosis are discussed.

Tuberculosis is still important as a disease of birds kept as pets and in zoos, and as a zoonosis. In living birds the diagnosis is difficult. In combination with the clinical and laboratory examination, radiology may help to lead to the diagnosis "generalised mycobacterial infection". Eight cases of tuberculosis seen in the clinic of our institute showed the different radiographic signs which may occur in the course of a mycobacterial infection. The specificity of the x-rays in combination with clinical and laboratory results is discussed.

Many radiological techniques are useful in fundamental research. Selected clinical problems in animals as well as certain basic research projects are utilized to emphasize the potential of radiological imaging. The author describes the use of several radiological methods in studies of how birds breathe.

An adult, female sulfur-crested cockatoo (Kakatoe sp) was examined because of dyspnea associated with hemoptysis. On radiographic examination there was a large cystic pulmonary mass that, on aspiration, was found to contain thick sanguineous fluid. Ziehl-Neelsen staining of aspirate smears revealed numerous acid-fast organisms. Gross necropsy and microscopic findings suggested a diagnosis of tuberculosis, with primary focus of infection in the pulmonary tissues. Bacteriologic isolation and typing confirmed a diagnosis of tuberculosis and established Mycobacterium avium as the etiologic agent.
