GOMEZ REBOLLO, Celestino et al. Urachal adenocarcinoma with late brain metastases. Arch. Esp. Urol. [online]. 2010, vol.63, n.7, pp.550-554. ISSN 0004-0614.

Objective: To describe a case of urachal adenocarcinoma with late brain metastases in a sixtyone year old man who presented abdominal discomfort and hematuria during six months. Methods: The clinical suspicion was bladder tumor and diagnostic studies were performed (urinary cytology, cystoscopy, abdominal ultrasound and abdominopelvic CT scan). Surgical treatment was performed. Results: Negative urinary cytology. Cystoscopy showed a lesion with infiltration of the bladder dome. Ultrasound and CT scan showed a five centimeter rounded lesion, with intermediate density, internal echoes and calcifications on the anterior supravesical middle line, that infiltrated the bladder. The extension study had not findings. Partial cystectomy and lymphadenectomy were performed. The histopathologic diagnosis was mucin-secreting urachal adenocarcinoma. After five years without disease the patient suffered lung and brain metastases. Conclusions: Urachal adenocarcinoma is a tumor which must be distinguished of primary bladder adenocarcinoma. The mucing-secreting adenocarcinoma can be associated with calcifications that can be demostrated on imaging studies. Late metastases without signs of local recurrence (after five years without disease) are an infrequent clinical-pathologic finding.
