Abstract

A 77-year-old woman with suspected lung carcinoma had multiple bladder masses and lymphadenopathy outside the normal urinary bladder drainage area. Fine needle aspiration and immunocytochemistry of the cervical lymph node complex and transurethral biopsy of the bladder masses confirmed metastatic small-cell neuroendocrine carcinoma.

Contribution: Clinical correlation, imaging findings, tumour markers and immunohistochemistry are necessary for metastatic bladder tumour work-up.
