Management of Calcified Uterine Mass

Initial Diagnostic Workup

Cross-sectional imaging with CT pelvis is the preferred modality for evaluating calcified uterine masses, as it provides superior delineation of calcification patterns compared to ultrasound or MRI, which directly impacts treatment planning 1
Peripheral rim calcification suggests prior UAE treatment or chronic degeneration 1
Central dystrophic calcification indicates hyaline degeneration and nonviable tissue 1

Before any intervention, patients must undergo complete gynecologic workup including Pap smear, endometrial biopsy if menometrorrhagia is present, cross-sectional imaging to exclude other pelvic pathology, and exclusion of pregnancy and active pelvic inflammatory disease 2, 3, 4, 5
Approximately 1 in 350 women undergoing surgery for presumed fibroids is found to have unsuspected uterine sarcoma, making tissue diagnosis important 2, 3, 4

The American College of Radiology recommends hysterectomy as the definitive treatment for postmenopausal patients with calcified fibroids causing heavy uterine bleeding or bulk symptoms after negative endometrial biopsy 6, 1
Myomectomy (laparoscopic or open) is appropriate for patients wanting to preserve the uterus, with equivalent quality of life improvement to UAE at 2 years, and is rated as "usually appropriate" by the American College of Radiology 1, 6
Hysteroscopic myomectomy is indicated only if the calcified fibroid is pedunculated submucosal and less than 5 cm in size 6, 1

Medical therapies have limited utility for calcified fibroids but may temporarily address bleeding symptoms while awaiting surgery, with first-line options including NSAIDs and estrogen-progestin oral contraceptives 1
Second-line options for preoperative preparation include GnRH agonists, GnRH antagonists, and tranexamic acid 1

Transvaginal ultrasound combined with transabdominal ultrasound is the preferred surveillance modality for asymptomatic calcified fibroids, although no specific consensus exists on imaging surveillance intervals 1

When encountering a calcified pelvic mass, consider ovarian tumors, especially teratomas with teeth/bone fragments, and CT is distinctly helpful in confirming the diagnosis of ovarian teratoma versus calcified fibroid 7
