Myxoid mesenchymal tumor with predilection for intracranial location harboring EWSR1 fusions with CREB family transcription factors is a recently described and exceedingly rare neoplasm. While some debate still exists whether this is a true separate entity or a myxoid variant of angiomatoid fibrous histiocytoma, these tumors still deserve separate attention due to localization, fairly distinct histology and higher incidence in the pediatric population. Data regarding outcome of these neoplasms are still sparse in medical literature. We report a case of an intracranial myxoid tumor with EWSR1-CREB1 fusion in a 14-year-old girl.
