Acquired Encephalocele, also known as secondary encephalocele, refers to the development of a skull defect that allows brain tissue to herniate or bulge through the opening. This condition usually occurs due to trauma, surgery, or infection. Several other terms are associated with Acquired Encephalocele, including Secondary Brain Herniation and Traumatic Encephalocele. These synonyms highlight the circumstances that might lead to the formation of the encephalocele. While it is crucial to identify and understand these synonyms, it is also essential to note that Acquired Encephalocele is a serious medical condition that requires immediate attention and proper treatment to prevent further complications and preserve brain function.
