The soap bubble appearance, also known as the bubbly appearance, has been described in dysembryoplastic neuroepithelial tumors (DNET). It describes a multi-loculated pseudocystic appearance of the DNET on T2 weighted images 1,2. These areas show partial suppression on FLAIR and are often associated with a bright rim of high signal (bright rim sign).
This bubbly appearance should not be mistaken for the salt-and-pepper appearance of polymorphous low-grade neuroepithelial tumor of the young (PLNTY), due to small distributed calcifications throughout the tumor 2.
