摘要
A 30-year-old female presented with an episode of generalized tonic-clonic convulsions. The imaging revealed multiple hemorrhagic lesions in the brain. There was no significant past history except for a cardiac surgery two years ago, for a benign atrial myxoma. The diagnosis of probable metastases was thought of and a thorough workup was planned, to determine the primary. Surprisingly, no primary lesion was detected, and therefore, as a histological diagnosis was required, she underwent navigation-guided excisional biopsy of one of the lesions. The histopathology proved that it was a myxomatous lesion. Thus, a rare diagnosis of atrial myxoma presenting as hemorrhagic metastases of the brain was formed. Atrial myxoma is a benign tumor of the heart. It can embolize distally and can present with known embolic/ischemic manifestations. However, presentation as hemorrhagic mass lesions, involving multiple areas of the brain, after many years of complete surgical excision, is quite rare and is rarely considered as a differential diagnosis. Hence, such a possibility should be kept in mind and careful primary cardiac intervention, with preventive measures to minimize the chances of distal embolization should be undertaken. As only few such cases have been reported worldwide, no treatment protocol has been devised at present, and a close follow-up of these patients is warranted.
