Abstract
Carcinoma of the urachus is very rare. Usually it has a typical appearance on computed tomography, with calcifications in a midline supravesical mass, but advanced stages of this neoplasm require malignancy evaluation that is not easy to establish. We report a case of a urachal tumor where CT scan did not properly assess the response to chemotherapy, while it did show an uncommon metastatic localization in the laterocervical soft tissues.
