Computed tomographic features of massive pneumoperitoneum in a dog with intestinal lymphoma – a case report

Anotace: A 6-year-old intact male Jindo dog was presented for reduced appetite, depression, and tympanic abdominal distension. Abdominal radiographs showed severe pneumoperitoneum and an intestinal mass. Computed tomography revealed massive pneumoperitoneum associated with intestinal perforation, with cervical and thoracoabdominal wall emphysema, pneumomediastinum, pneumoretroperitoneum, pneumoscrotum, and peritonitis. Surgery confirmed a ruptured jejunal mass, and histopathologic evaluation of the excised tissues revealed intestinal lymphoma. Clinicians should therefore consider the possibility of gastrointestinal perforation in patients with severe pneumoperitoneum even where there is no history of trauma. Despite clinical stability, intensive monitoring and urgent decompressive intervention should be performed in patients with severe pneumoperitoneum.
