👉 Pleiomastia is a medical condition characterized by an enlarged, fibrous sac or cluster of cells in the brain. It occurs due to inflammation or trauma that causes tissue destruction and replacement with new tissue. Pleiomastia can be either benign or malignant depending on whether it's caused by a tumor or an infection. It's often seen in people who have undergone surgery or had other surgeries, as well as those who are undergoing chemotherapy or radiation therapy.
