Ureteral Obstruction and Renal Complications in a 35-Year-Old Woman with a Large Mature Cystic Teratoma

“…Malignant degeneration can occur in 1-2% of teratoma cases (2). Large ovarian teratomas can compress abdominal organs and vasculature, causing complications such as small bowel obstruction, pelvic vein thrombosis, lower extremity lymphedema, and hydronephrosis (4,5).…”
