Christmas Tree Pattern Bladder

A pine cone bladder or Christmas tree bladder is a cystographic appearance in which the bladder is elongated and pointed with a thickened, trabeculated wall. It is typically seen in severe neurogenic bladder with increased sphincter tone (detruso. His bladder was vertically elongated, with irregular contours due to granulation column formation, diverticula and upper urinary tract dilatation.

Such a bladder is called a Christmas tree bladder or pine cone bladder. We report a rare case of non- neurogenic 'Christmas tree' urinary bladder in a 30-year-old man with urethral stricture diagnosed on voiding cystourethrography (VCUG) and retrograde urethrography (RUG) with review of the relevant literature. A "Christmas tree" (Fig.

1) has been used to describe the appearance of a hypertonic, neurogenic bladder, as seen on cystography (Fig. 2) [1]. The bladder is vertically oriented and has a wide base that tapers superiorly towards the dome with irregular walls from associated trabeculations.

The conical shape of the bladder has also been referred to as a "pine cone" bladder. Although. A cystography showed Christmas tree bladder (CTB) and important post.

MeSH terms Cystography / methods Humans Tomography, X-Ray Computed / methods* Urinary Bladder / diagnostic imaging* Urinary Bladder Diseases / diagnostic imaging*. Neurogenic bladder typically occurs in those with sacral abnormalities at birth. The appearance has been described as a Christmas tree or pine cone bladder.

The shape of the bladder is highly abnormal, with an elongated appearance and a dome. Surprisingly, Christmas Tree Bladder isn't related to this festive time of year, despite its name. In fact, It's a medical term that describes the distinctive appearance of the bladder on imaging scans.

When viewed during certain tests, like a cystography, the bladder takes on an elongated, pointed shape with irregular outlines. 'Christmas tree' bladder describes the radiological appearance of a severely neurogenic bladder. The bladder wall is thickened and trabeculated and the subsequent irregular contour gives the appearance of decorations hanging from a Christmas tree.

Neurogenic bladder is defined as urinary bladder malfunction due to neurologic dysfunction. A pine cone bladder or Christmas tree bladder is a cystographic appearance in which the bladder is elongated and pointed with a thickened, trabeculated wall. It is typically seen in severe neurogenic bladder with increased sphincter tone (detrusor sphincter dyssynergia) due to suprasacral lesions (above S2-S4) or epiconal lesions (in and around.
