Surgical removal of a seminoma from a black sea bass.
An adult black sea bass was examined because of abdominal distention and decreased appetite. A large abdominal swelling was evident and was firm on palpation. Differential diagnoses included neoplasia, abscess or granuloma, hematoma, or swim bladder abnormality. Diagnostic tests included survey radiography, positive-contrast radiography, and computed tomography. The sea bass was anesthetized with tricaine methanesulfonate. A ventral midline abdominal incision was made, and adhesions to the mass were gently dissected. The fish recovered without complications. Radiography was repeated 8 weeks after surgery, and there was no evidence of mass regrowth. To the authors' knowledge, this is the first report of a barium enema being performed in a fish. Although surgical procedures are performed more commonly on fish for research, a few reports of clinical surgical cases have been described. Our experience supports the conclusions of other reports that certain surgical procedures can be performed safely in fish.
