Cyst or Tumor?

Patient: Hello, i’m only 30 years old and I have blood come out at the end of my urine. Lately, I’ve been straining and it feels as I have more urine to come out, but instead of urine, its mainly blood. I’ve done blood tests, urine tests and everything came out normal including my blood. They performed an ultrasound and found what it seemed to be a mass on my bladder. I was then recommended to get a CT scan of my abdomen and pelvis with contrast. From their findings, there is a complex well-defined mass in the superior aspect in the anterior dome of the bladder. The mass measures 6 cm in transverse dimension and 7.5 cm in maximal AP dimension. There is minimal peripheral calcification. The mass appears to be growing from the bladder or may be indenting into the bladder. There is a small focal hypodensity in the subcapsular anterior aspect of the medial segment of the left lobe of the liver. This is a classic location for focal fatty infiltration. Otherwise, the liver is unremarkable. The spleen, adrenals, pancreas, gallbladder, and kidneys are normal in morphology and enhancement. There is no significant lymphadenopathy. There is no ascites. Bowel loops appear to be grossly normal. The sigmoid colon is partially displaced by this mass. However, it appears to be separate from this lesion. The lesion has somewhat of a dumbell appearance with the inferior segment pushing into the bladder margin.
