No symptoms, regular menses, no dysmenorrhea, mild hydroureter and hydronephrosis, CA125 = 379.0 U/mL,
LDH = 245.0 IU/L.
Laparotomy, enucleation of the cyst in one ovary, drainage of that in the other.
Gogacz et al., 2012 [26] 11 On US, a well encapsulated tumor (capsule approximately 3 mm thick) with homogeneous content, located behind the uterus.
