A 3-year-old neutered male domestic medium-hair cat presented for sudden onset of vomiting and anorexia. Ultrasonographically, severe distension of the cecum by hyperechoic material associated with variable posterior attenuation was identified. The cecum was surgically excised. A retention cyst cecal mucocele complicated by mucosal ulceration and inflammation was diagnosed. A literature review of this well-described lesion in humans, once described in dogs but as yet undescribed in cats, is briefly presented.
