A Rare Instance of Lung Cancer Metastasizing to the Urinary Bladder
摘要
Secondary bladder neoplasms from distant metastases are rare. Most cases are found in autopsy studies or in advanced stages. The diagnosis remains a challenge. We herein report a rare case of a 61-year-old male, who presented with bilateral hydronephrosis and thickening of the bladder wall, as well as elevated carcinoembryonic antigen. After a meticulous survey, metastatic carcinoma of the urinary bladder from the lung was diagnosed despite an initial normal appearance of the bladder mucosa on cystoscopy. The patient expired 8 months later despite treatment with chemotherapy. The incompatibility between the findings of computed tomography and the cystoscopic appearance provided an important clue for the diagnosis.
