Plain-English summary

A 6-year-old Staffordshire bull terrier was brought in after showing signs of extreme tiredness, fluid buildup in the abdomen, and difficulty exercising over the past month. An ultrasound of the heart revealed a 3 cm mass blocking the right atrium, which was causing fluid accumulation around the heart and lungs. Further tests confirmed that the mass was a type of heart tumor called a rhabdomyoma. Unfortunately, the prognosis for this condition can be serious, and treatment options would need to be discussed with a veterinarian.

Abstract

A six-year-old Staffordshire bull terrier had a four-week history of progressive lethargy, ascites and exercise intolerance. A mass 3 cm in diameter obliterating the right atrial lumen was detected by echocardiographic examination. There were lactescent pericardial and serosanguineous pleural effusions. Histological and immunochemical examinations showed that the mass was a primary rhabdomyoma.
