Pelvic Mass by Approximate Frequency and Age Group

Infancy

  • Functional ovarian cyst
  • Germ cell tumor

Prepubertal

  • Germ cell tumor

Adolescent

  • Functional ovarian cyst
  • Pregnancy
  • Dermoid / other germ cell tumors
  • Obstructing vaginal / uterine anomalies
  • Epithelial ovarian tumors

Reproductive

  • Functional ovarian cyst
  • Pregnancy
  • Uterine fibroids
  • Ovarian epithelial tumors

Perimenopausal

  • Fibroids
  • Ovarian epithelial tumors
  • Functional cysts

Postmenopausal

  • Ovarian tumor (malignant or benign)
  • Bowel, malignant tumors or inflammation
  • Metastases

 

Prepubertal Age Group

  1. Clinical Presentation:
  2. ¬ Abdominal mass

    ­ Acute abdominal pain: often associated with torsion

    v In girls younger than 9 y/o, approximately 80% of the ovarian neoplams were found to be

    malignant. Germ cell tumors account for approximately 60% of ovarian neoplasms in children

    and adolescents.

  3. Differential Diagnosis: Wilms’ tumor, neuroblastoma, etc.
  4. Diagnosis and Management: (Figure 13.11, p355)

 

Adolescent Age Group

  1. Differential Diagnosis:
  1. Ovarian Masses:
  2. V Functional ovarian cysts: an incidental findings, or presented with pain caused by torsion,

    leakage or rupture.

    V Endometriorsis: less common in adolescence than in adults.

  3. Uterine Masses: (rare)
  4. V Obstructive uterovaginal anomalies: imperforate hymen, transverse vaginal septa, vaginal

    agenesis with a normal uterus and functional endometrium, vaginal duplications with

    obstructing longitudinal septa, and obstructed uterine horns.

    ä hematocolpos, hematometra

    V Myomas are not commonly seen in this age group.

  5. Inflammatory Masses:
  6. V Adolescents have the highest rates of PID of any age group, if one considers only individuals

    at risk for STDs.

    V Eg. tubo-ovarian complex (a mass consisting of matted bowel, tube, and ovary),

    tubo-ovarian abscess (a mass consisting primarily of an abscess cavity within an anatomically

    defined stucture such as the ovary), pyosalpinx, or, chronically, hydrosalpinx.

  7. Pregnancy-Related Causes: eg. ectopic pregnancy
  1. Diagnosis: history, PV, lab. studies (including EIA), ultrasonography, etc.
  2. Management: (Figure 13.11, p355)

 

Reproductive Age Group

  1. Conditions Diagnosed as A “Pelvic Mass” in Women of Reproductive Age:
  2.  

    Full urinary bladder

    Urachal cyst

    Sharply anteflexed or retroflexed uterus

    Pregnancy (with or without concomitant myomas):

    Intrauterine

    Tubal

    Abdominal

    Ovarian or adnexal masses:

    Functional cysts

    Inflammatory masses:

    Tubo-ovarian complex

    Diverticular abscess

    Appendiceal abscess

    Matted bowel and omentum

    Peritoneal cyst

    Stool in sigmoid

    Neoplastic tumors:

    Benign

    Malignant

    Paraovarian or paratubal cysts

    Intraligamentous myomas

    Less common conditions that must be excluded:

    Pelvic kidney

    Carcinoma of the colon, rectum, appendix

    Carcinoma of the fallopian tube

    Retroperitoneal tumors (anterior sacral meningocele)

    Uterine sarcoma or other malignant tumors

  3. Diagnosis: history, PV, lab. studies (including EIA), ultrasonography, etc.
  4. Management:

1). Myoma Uteri:

  1. Non-surgical: first line
  2. À follow-up of symtoms and signs, and uterine size

    Á GnRH analog

    Â low-dose hormonal therapy

  3. Surgical:

G Indications:

À Abnormal uterine bleeding with anemia, unresponsive to hormonal management

Á Severe dysmenorrhea, dyspareunia, or lower abdominal pain, etc.

 Acute pain, as in torsion of a pedunculated myoma or

prolapsing submucous myoma

à Urinary S/S, such as hydronephrosis.

Ä Rapid enlargement of the uterus during the premenopausal years, or any increase

in uterine size in postmenopaused females

Å Infertility, with myoma as the only finding

Æ Enlarged uterus with compression symptoms or discomfort

G OP methods:

À Myomectomy: abdominal, vaginal, laparoscopic, hysteroscopic, etc.

Á Hysterectomy

2). Ovarian Masses:

- Functional tumors: expectant therapy

- Symptomatic cysts:

À Analgesia: first-line

Á Surgery:

v Indications: significant pain, or suspicion of malignancy

v OP methods:

a). laparotomy: when R/O malignancy

b). laparoscopy only used in

c). aspiration low risk of malignancy

 

Postmenopausal Age Group

  1. Diagnosis: PV, ultrasonography, CA-125 ð to rule out malignancy
  2. Management:
  1. Non-surgical:
  2. When the cyst is asymptomatic, small (< 5 cm in diameter), unilocular, and thin-walled.

  3. Surgical: R/O malignancy

 

 

Ultrasound Scoring system for Adnexal Masses

Clear cyst and smooth border

1

Clear cyst with slightly irregular border; Cyst with smooth walls but low-level echoes (i.e. Endometrioma)

2

Cyst with low-level echoes with slightly irregular border but no nodularity (i.e. Endometrioma); clear cyst in postmenopausal patient

3

Equivocal, nonspecific ultrasound appearance: solid ovarian enlargement or small cyst with irregular borders and internal echoes (hemorrhagic cyst or benign ovarian tumor)

4-6

Multiseptated or irregular cystic mass consistent in appearance with ovarian tumor (7 = less nodularity; 8-9 = more nodularity)

7-9

Pelvic mass as above, with ascites

10

· 1 = benign; 10 = malignant
