Summary
Urachal carcinoma, a rare cancer, can spread to the brain. Early MRI diagnosis and gamma knife radiosurgery effectively treated brain metastases in this case.
Area of Science:
- Oncology
- Neurology
- Radiology
Background:
- Urachal carcinoma is a rare and highly malignant cancer originating from the urachus.
- Brain metastases from urachal carcinoma are exceptionally uncommon, posing diagnostic and therapeutic challenges.
Observation:
- Contrast-enhanced MRI identified brain metastases in a patient with urachal carcinoma.
- A large metastatic mass was surgically resected.
- Four smaller metastatic lesions were treated with gamma knife radiosurgery.
Findings:
- Post-radiosurgery MRI at six weeks showed complete resolution of the four treated metastatic lesions.
- The study highlights the effectiveness of gamma knife radiosurgery in managing brain metastases from urachal carcinoma.
Implications:
- Early diagnosis of urachal carcinoma brain metastases is crucial and can be achieved with MRI.
- Gamma knife radiosurgery presents a viable and effective treatment option for these rare metastases.
- This case underscores the importance of considering urachal carcinoma in the differential diagnosis of unexplained brain masses.
