Significance of incidentally identified bullae and blebs on thoracic computed tomography and prevalence of subsequent pneumothorax in dogs.

Objective: To determine the prevalence of incidentally found pulmonary bullae and blebs (PBBs) in a population of dogs undergoing thoracic computed tomography (CT) for reasons other than presence of pneumothorax and to determine the prevalence of subsequent spontaneous pneumothorax (SP) development.

Study Design: Retrospective study.

Animals: A total of 30 dogs.

Primary small intestinal lymphangiosarcoma in a dog presenting with a segmental partial mesenteric volvulus.

A 3-year-old Great Dane presented with a history of chronic vomiting and diarrhoea. Abdominal computed tomography followed by exploratory laparotomy revealed a perforated, segmental partial mesenteric volvulus, affecting an abnormal section of distal jejunum, which was resected. Histopathology and immunohistochemistry results were consistent with jejunal lymphangiosarcoma.
