Case Discussion

A pine-cone ( aka Christmas tree ) bladder is the name given to the fluoroscopic appearances of a neurogenic bladder.

Instead of the symmetrical 'ball-like' normal appearance, the bladder is elongated and shaped like a pine cone tree, being narrow at its dome. The wall is trabeculated and the capacity of the bladder is low.
