Publication Date: 2022-06-27
History
11 year old male castrated mix breed dog. 11 days of anorexia/weakness. Weight loss
6 images
Findings
Abdominal serosal detail is normal.
The prostate is enlarged and there are multiple punctate to linear, faintly mineral opaque structures superimposed with the prostate.
Only identified on the ventrodorsal image, there is the impression of an ill-defined, focal area of moth-eaten osseous lysis with associated mild sclerosis of the right ilial wing. There is undulant margination along the lateral aspect of the right ilial wing. There are two, well-defined, rounded, metal opaque structures within the soft tissues of the mid-aspect of the right body wall and ventral to the tail base, consistent with incidental ballistic projectiles.
The stomach contains a mild volume of heterogeneously soft tissue opaque material and gas. The small intestines contain mild volumes of both homogeneously and heterogeneously soft tissue/fluid opaque material and gas and are uniform in size. The colon contains a mild volume of heterogeneously fecal material and gas. The liver, spleen, kidneys and urinary bladder are normal.
Diagnosis
- Prostatomegaly with pinpoint mineralization is most concerning for neoplasia (i.e. prostatic carcinoma)
The appearance of the right ilial wing is most concerning for neoplasia such as a metastatic lesion from possible prostatic neoplasia. A primary osseous neoplasia (such as osteosarcoma or round cell neoplasia) is possible. An infectious process (such as secondary to fungal disease) is considered less likely.
- The heterogeneous material within the stomach and small intestine is likely incidental ingesta.
Discussion
The thoracic radiographs ( not provided here) did not show any evidence of pulmonary metastasis. The patient was confirmed to have prostatic carcinoma on a prostatic wash.
