This 8 year old MN Shih Tzu has a history of bladder stones managed by diet (Urinary S/O). On physical exam a mid-abdominal non-painful mass was palpated.
This 8 year old MN Shih Tzu has a history of bladder stones managed by diet (Urinary S/O). On physical exam a mid-abdominal non-painful mass was palpated.
The urinary bladder, trigone and pelvic urethra presented normal wall thicknesses with anechoic urine and normal tone. Small bladder calculi were noted. This appears small enough to pass at 0.2 cm and was non obstructive at this time. A trace amount of free fluid was noted adjacent to the bladder.
A mineralizing, caudal abdominal mass was noted in this patient with progressive shadowing. This appears to be free within the abdomen and mildly vascular. This is likely of lymph node origin. There was shadowing noted, which is consistent with mineralization or fibrosis with a mild potential for foreign matter. The mineralization or fibrosing process would suggest a low grade chronic pathology.
Surgical intervention is recommended. There is a minor potential that this derives from
intestinal wall, yet direct connection to the intestine could not be localized. Urine
culture would be warranted if not already performed. Ultrasound-guided FNA of the
mass could be performed, yet direct resection is likely the best option as this appears to
be isolated. This is possibly a granuloma and likely non neoplastic.
