CASE DESCRIPTION: A 6-year-old Siberian Husky-mix @entity235 was examined for episodes of collapse. CLINICAL FINDINGS: Physical examination, echocardiography, abdominal ultrasonography, ECG, and thoracic computed tomography with contrast were performed and revealed a 2.5   2.3   2.0-cm mass over the pulmonic @entity340 , resulting in moderate @entity849 . Other abnormal findings included systemic @entity101 , @entity714 , @entity644 , and a urinary bladder mass. TREATMENT AND OUTCOME: Pulmonary arteriotomy was performed under @entity432 , and the mass was resected with transesophageal echocardiographic guidance and direct visualization. Results of histologic examination of the mass revealed @entity4607 . Sequential follow-up examinations and telephone contacts (at 0.5, 5, and 15 months after surgery) revealed that the @entity1 had been free from episodes of collapse since surgery. No regrowth of the mass was noted on follow-up echocardiograms, and the @entity849 had resolved, although mild to moderate @entity338 later developed. The bladder mass was excised 15 months after the first surgery when @entity811 developed, and results of histologic examination of this mass revealed @entity4607 . The @entity235 was eventually euthanized 31 months after the initial surgery for reasons that could not be directly linked to any recurrence of the pulmonary artery mass. CLINICAL RELEVANCE: @entity4607 are @entity5 that can be located in various tissues, including large arteries. Computed tomography was helpful in predicting the resectability of the @entity4615 in this @entity235 . Treatment with arteriotomy under @entity432 and mild @entity2332 resulted in a favorable outcome.
