👉 An articular cyst, also known as an articular sac, is a type of benign tumor that typically occurs in bones or soft tissues. These tumors are characterized by their resemblance to a small, round ball or cluster of cells commonly found within the articulations between bone and cartilage. Articulipomas can be congenital or acquired, with some cases occurring due to trauma or infection. They are often asymptomatic but may present with pain or tenderness in affected areas.
