Introduction
Myxomas are benign tumors of the mesenchymal origin and account for about half of the benign cardiac tumors. Occasionally, they occur at other locations, but the intracranial manifestation of a myxoma is exceptionally rare. As a secondary neoplasia following radiotherapy, myxoma has only been reported once in the literature.
Material and methods
A 12-year-old girl, who was previously treated for a medulloblastoma, was diagnosed with a new lesion at the left transverse sinus in the follow-up magnetic resonance imaging (MRI). Indication for surgery was made and complete removal could be achieved.
Results and discussion
Histological examination revealed a myxoma. Further staging showed no other manifestation of the myxoma. The close relation to the radiation field of the posterior fossa makes it highly suggestive that the myxoma developed as a secondary neoplasia induced by radiotherapy. Treatment philosophy for this benign tumor entity is a completed resection of the lesion with regular follow-up MRI.
