| Case | Age(years) | Breed | Sex | Symptoms | Duration(days) | Surveyradiography | Ultrasonographic findings | Surgicalfindings | Underlyingdisease | Therapy | |
|---|---|---|---|---|---|---|---|---|---|---|---|
| Transverse section | Longitudinal section | ||||||||||
| 1 | 9 | DSH | F | A, V, D | 8 | Soft-tissue opacity in the middle abdomen, small intestinal dilatation | Target-like mass of 3.2 cm in maximal width. Isoechoic ring of 0.8 cm in width surrounds a C-shaped hyperechoic centre | Ovoid mass of 2.5 cm in maximal width. Hypoechoic rim of 0.8 cm in width surrounds a hyperechoic centre | I-C | Intestinal lymphoma | Eu |
| 2 | 3 | DSH | F | A, V, D | 5 | NA | Target-like mass of 2.5 cm in maximal width. Multiple, hyperechoic and hypoechoic concentric rings of 0.8 cm in width, surround the hyperechoic centre | Multiple, hyperechoic and hypoechoic parallel lines of 2.1 cm in maximal width | I-C | Parasitic enteritis | IRA |
| 3 | 1 | S | F | A | 7 | NA | Target-like mass of 2.4 cm in maximal width. Multiple, hyperechoic and hypoechoic concentric rings of 0.8 cm in width, around hyperechoic centre. Part of small intestine into the centre | Multiple, hyperechoic and hypoechoic parallel lines of 2.1 cm in maximal width | J-J | Parasitic enteritis | IRA |
| 4 | 10 | S | M | A | 7 | Small intestinal dilatation, possible intestinal mass | Target-like mass of 1.6 cm in maximal width. Outer hyperechoic of 0.2 cm in width and inner hypoechoic of 0.2 cm in width concentric rings around a circular hyperechoic centre. Focally increased thickness of the outer concentric ring compatible with intestinal mass | Kidney-like mass (ie pseudo-kidney) of 1.8 cm in maximal width | I-C | Intestinal lymphoma | Eu |
| 5 | 2 | S | M | A, D | 10 | Reduced serosal detail, large intestinal dilatation | Target-like mass of 3.2 cm in maximal width. Hypoechoic ring of 0.9 cm in width surrounds a small hyperechoic centre | Ovoid mass of 2.5 cm in maximal width, consisting of 0.8 cm in width hypoechoic rim around hyperechoic centre | I-C | Intestinal lymphoma | Eu |
| 6 | 1 | S | F | A, V | 5 | Small intestinal dilatation | Target-like mass of 2 cm in maximal width. Multiple, hyperechoic and hypoechoic concentric rings of 0.6 cm in width around hyperechoic centre and part of small intestine. Anechoic areas into the centre | Multiple, hyperechoic and hypoechoic parallel lines of 1.6 cm in maximal width | I-C | Intestinal lymphoma | IRA |
| 7 | 1.2 | DSH | F | A | 6 | Small intestinal dilatation | Target-like mass of 2.6 cm in maximal width. Multiple, hyperechoic and hypoechoic concentric rings of 0.6 cm in width around hyperechoic centre. Part of small intestine into the centre | Multiple, hyperechoic and hypoechoic parallel lines of 2.2 cm in maximal width | I-C | Parasitic enteritis | IRA |
A palpable abdominal mass was revealed in all cases.
