title: Intraosseous ganglion communicating with soft tissue counterpart.
abstract: We report the imaging and pathological findings of a rare case of intraosseous ganglion communicating with extraosseous counterpart. Both counterparts contain air and show rim-enhancement on T1-weighted images. Histopathologically, the enhanced-rim consists of reactive proliferation of capillary vessels due to degeneration.
