Abstract

Breast cancer is most frequently metastasize dura, bone and parenchyma in cranial tissue. Symptoms vary according to the location of the metastasis. Masses may be solid, cystic and partial cystic form. Cystic intracranial metastases of breast cancer is very rare. Radiotherapy and/or chemotherapy could be performed after surgery. Forty-eight-year-old female patient was admitted with complaints of headache and generalized tonic-clonic seizure. Patient underwent surgery for cancer of the left breast for eight years ago. Left total mastectomy and left axillary lymphadenectomy was performed. Pathology was determined as adenoid cystic carcinoma. Adjuvant chemotherapy was applied to patients with lymph nodes metastasis detected. Cranial MRI (Magnetic Resonance Imagination) was performed after eight years after breast surgery. In the left frontal and cerebellar midline, large cystic mass lesions were detected in cranial MRI. PET–CT (Positron Emission Tomography) examination was not detected in any other organ metastases. There was no pathology in terms of breast surgery consultation. Both cranial lesions were underwent surgery twice in one week. In the pathological examination of the patient, cystic breast cancer metastasis was detected. Whole brain radiotherapy was performed to the patient after surgery. We want to emphasize that in cranial cystic metastasis, rarely come across if breast cancer metastasis should be considered in differential diagnosis.
