A rare and unusual case of isolated cerebellar metastasis from a non-muscle invasive transitional cell carcinoma of bladder

Cerebellar metastases from superficial bladder cancer are extremely rare. Bladder cancer is the second most common cancer of the urinary tract. It is the fourth most common cancer in men and eight most common in women in Europe where its incidence is estimated at 104,000 in 2006. Seventy percent of bladder cancer is confined to the mucosa (Ta, CIS-T1), but 30% is invasive. The most common solid organs with metastatic spread are lung (24–36%) and liver (21–35%). Brain metastases are rare, with previous estimates at 0.3–8%. We present the case of a successfully treated solitary cerebellar metastasis that presented 11 months following resection of organ-confined transition cell carcinoma.
