The incidence of hemorrhage in metastatic neoplasms is highest in melanoma, hypernephroma, bronchogenic carcinoma, and choriocarcinoma. Other metastatic tumours that bleed are breast and thyroid metastasis. Of the primary intracranial neoplasms, hemorrhage occurs most frequently in relation to pituitary neoplasms. Other primary tumors that have been reported to bleed include glioblastoma multiforme, lower-grade gliomas, ependymomas, choroid plexus papillomas, sarcomas, and meningiomas.
Our patient is 55 yr old male and shows large ring enhancing, slightly hyperintense lesions in parietal and frontal region. Lesions are hyperintense on both T1 and T2 weighted images and show ring enhancement on contrast study. This appearance is very suggestive of secondaries from renal cell carcinoma.
