[Metastatic Brain Tumor from Urachal Cancer:A Case Report].

Urachal cancers usually do not metastasize until the late stages, and local invasion and recurrence are observed with high frequency. We report a rare case of brain metastasis from urachal cancer in a 67-year-old female. She presented with abnormal behavior and right hemiparesis that started one month previously. MRI revealed a 55-mm lesion in the left frontal lobe, 5-mm in the right parietal lobe, and 2-mm lesion in the left cerebellum. The tumors showed ring enhancement on gadolinium-enhanced T1WI and were suspected to be metastatic brain tumors. Craniotomy was performed to excise the biggest tumor;the histological diagnosis was a poorly differentiated adenocarcinoma. As a result of the search for the primary tumor, the urachal carcinoma and multiple lung metastases were found. The patient chose best supportive care after diagnosis and died due to progression of multiple systemic metastases five months after surgery.
