We present a case of brain metastases of the urachal carcinoma, which is extremely rare and malignant. Contrast-enhanced MRI was employed to detect them. A large mass was removed surgically and 4 other small metastases were treated by gamma knife radiosurgery. Six weeks after radiosurgery, the 4 lesions had disappeared on MRI. We emphasise the importance of early diagnosis using MRI and treatment by radiosurgery for this rare condition.
