Transitional cell carcinoma (TCC) in dogs.

A: Longitudinal sonogram of an extensive TCC affecting the ventral and dorsal bladder wall, in a 10 year old Lhapsa Apso.  B: In the same dog as A. the TCC extends caudally into the bladder neck and urethra (U).  C:  A cauliflower shaped nodule arising from the craniodorsal wall was found incidentally in a dog presented for urinary obstruction secondary to a urethral calculus. It was confirmed as papillary non infiltrating TCC after surgical removal. D: Longitudinal sonogram of a broad-based hyperechoic mass associated with the craniodorsal bladder wall, consistent with transitional cell carcinoma. E: Longitudinal sonogram in another dog without urinary clinical signs in which focal irregular thickening of the dorsal bladder wall was detected incidentally. Color Doppler signal (arrow) confirmed that this lesion was attached to the bladder wall, as opposed to a blood clot. F: Two separate transitional cell carcinoma masses (M1 and M2) in another dog with mineralization causing acoustic shadowing (*). The arrowheads delineate the apical bladder wall.

The bladder wall is typically altered in thickness and sometimes in uniformity, shape and contour in cases of cystitis. In this 12 yr-old female Poodle dog presented for chronic dysuria and pollakiuria, this sonographic image was suggestive of cystitis.

As we know however, the appearance of the bladder wall can be greatly influenced by the amount of luminal distension. And since that dog had been treated with several antibiotics and showed important signs of dysuria, an obstructive lesion remained suspected. It was suggested that a follow-up exam be formed with a full bladder. Here is what was seen on that second exam performed the following day

The bladder wall was now smooth and normal in thickness. At the trigone, an irregularity was now detected and urethral wall thickening was now obvious. Ill-defined hyperechoic areas were also noted in the ventral urethral wall suggesting mineralization. These features are consistent with a transitional cell carcinoma, which was masked by the artifactual thickening of the bladder wall due to insufficient distension.

This story is not that remarkable. I’m sure you’ve experienced that more than once. Ultrasound is a great modality. But pitfalls like this one exist – a lot!- and may lead to false diagnoses.

Be careful now not to slip on those ultrasound banana peels! :-)

A sonographic view of a dilated bladder after two days from the onset of acute obstruction. Note the bladder filled with clear anechoic fluid represents urine. An increased dimension over the normal was clear (A). The clear anechoic fluid inside is mixed with some echogenicity representing cystitis. Note the acoustic enhancement in the far field of the image (B).
