Cardiac phoenix in the brain-occult intracranial hemorrhagic metastases from completely resected atrial myxoma

Abstract

Background: Cardiac myxomas are sporadic in nature and can often recur with a frequency of 3%, especially in middle-aged women, and 22% of the cases account to a part of Carney complex. Complete surgical removal of the myxoma is usually curative. Recurrence has been related with partial surgical excision, multicentricity, and embolism of tumor fragments. Case Description: We report a case of a patient with single brain metastases due to tumor embolization, from a cardiac myxoma operated prior. This case is exclusive, as tumor embolization from atrial myxoma to the cerebral cortex can be possible, within a short duration. In our case, the patient was evaluated with a magnetic resonance imaging brain and a solitary hemorrhagic lesion in the eloquent cerebral cortex was observed. To determine the primary etiology, the diagnosis of probable metastases was thought of, and a thorough workup was planned. Surprisingly, no primary lesion was detected, and as a histological diagnosis was required, he underwent a navigation-guided excisional biopsy of lesion. The biopsy was indicative of a metastatic deposit from an atrial myxoma. Conclusion: In eloquent cortex lesions, gross total resection is challenging for a neurosurgeon especially when the patient has no significant neurological deficits. Timely gross total resection of a solitary metastatic lesion can improve the patient’s outcome and can enhance early recovery with less or no morbidity.
