Urinary Bladder - Hemorrhage
comment:
Hemorrhage can be seen anywhere in the bladder. It is commonly associated with inflammation, calculi, or the presence of tumors ( Figure 1

recommendation:
Hemorrhage is usually a secondary finding and should not be diagnosed unless it is a major component of the overall lesion and important in the pathogenesis of the lesion. Perimortem hemorrhage should not be diagnosed.references:
