Multimodality appearances of a neurogenic bladder. The bladder becomes elongated as opposed to its normal 'ball-like' appearance, with an apex in the cranial direction. In addition the bladder wall becomes trabeculated - the combined appearances give the distinct Aunt Minnie appearance of a Christmas tree bladder.
In this case a number of other interesting additional findings are present:
- left sided undescended testis
- chronic right hydronephrosis
- iatrogenic abnormality of a urethral catheter balloon inflated in the posterior urethra - this may be possible depending on the patient's neurogenic status. Inflate a balloon in the posterior urethra beyond 2-3 mL in a normal patient and they/you will know it!
