Key result
Digital subtraction angiography proves optimal for diagnosing cerebral oncotic aneurysms from atrial myxoma.
Why the study?
Myxomatous cerebral (oncotic) aneurysms following atrial myxoma represent a rare neurological complication with indefinite and variable aneurysm characteristics and no definite therapy guidelines.
Case Report (n=1)
Highlights the rare neurological complication of oncotic cerebral aneurysms following atrial myxoma and the role of multimodality imaging in diagnosis.
Alerts clinicians to consider cerebral aneurysm screening in pediatric atrial myxoma; leaves open optimal surveillance and intervention strategies.
BACKGROUND: Myxomatous cerebral (oncotic) aneurysms following atrial myxoma is a rare neurological complication. CASE REPORT: We report an 11-year- old boy with left atrial myxoma and multiple cerebral oncotic aneurysms. The characteristics of these aneurysms are indefinite and variable. The "Metastasize and Infiltrate" theory may be the key mechanism in the formation of these aneurysms. CONCLUSIONS: Magnetic resonance imaging (MRI), computed tomography (CT) and angiography are useful in the diagnostics while digital subtraction angiography (DSA) is the best option. There are no definite guidelines for therapy of these aneurysms. Resection of cardiac myxomas, chemotherapy, radiotherapy, coil embolization and surgical treatment could be helpful.

Gupta et al. (2015) conducted a case report in Left atrial myxoma and multiple cerebral oncotic aneurysms (n=1). Imaging diagnostics (MRI, CT, DSA) was evaluated. Digital subtraction angiography was identified as the optimal diagnostic imaging modality for multiple cerebral oncotic aneurysms in an 11-year-old boy with left atrial myxoma.
