2017 Image Interpretation - Case 2
- Presented to our emergency service for restlessness, panting, and discomfort; two episodes of vomiting in the previous week.
- On physical exam, the dog had a tense painful abdomen and was tachycardic/panting.
- Ultrasound was performed to further evaluate these clinical signs and history.
- An irregular hypoechoic mass is present in the right mid-abdomen
- The mass has vascular markings (color doppler)
- Part of the mass is continuous with a gas interface. The gas interface is thin walled and can be followed to the ileocolic junction.
- Cecal mass
- Consider neoplasia (GIST, leiomyoma, leiomyosarcoma, other). Granuloma and abscess less likely; adhered lymph node (lymphadenopathy) cannot be ruled out.
- Mass removed surgically; histology revealed either leiomyosarcoma or GIST. IHC consistent with GIST.
- The dog died post-op, the cause of death is unknown.
