2. Ovaries are normally not palpable in pre-menarche, and after the menopause
In the reproductive age group ovaries are palpable in the lean pts.
Ovarian size of different age groups
Premenopause 3.5 x 2 x 1.5 cm
Early menopause 1 – 2 yrs
2 x 1.5x0.5cm
Late menopause 2-5yrs x0.75x0.5cm

3. If the ovaries are palpable in any of the age groups when it is not supposed to be through investigations and work up should be carried out
OVARIAN CYSTS CAN BE CLASSIFIED AS FOLLOWS:
I. Functional Benign
II Neoplastic borderline
Malignant

4. FUNCTIONAL OVARIAN CYSTS INCLUDES:
a. Follicular cysts
b. Corpus luteum cysts
c. Theca luten cysts
BENIGN OVARIAN NEOPLASM
1. Serous cystadenoma
2. Mucinous cystadenoma
3. Endometrioma
4. Dermoid cysts
5. Fibroma

5. FUNCTIONAL CYSTS
These are cysts related to ovarian function i.e. the process of ovulation
They are the most common detected cysts in the reproductive age group
Can be reach up to 10 cm in diameter
Resolve spontaneously.

6. Follicular cysts results from the growth of a follicle that does not rupture
Corpus luteum cyst results from Hge inside a corpus luteum
Theca luteum cysts result from over stimulation of the ovary by HCG. Not common in normal pregnancy but common in molar pregnancy, choriocarcinoma and reproductive technology

7. - 80% of ovarian neoplasm are benign Benign ovarian neoplasia
- Benign ovarian neoplasm can be solid or cystic

8. Serous Cystadenoma (Commonest)
- Usually do not reach very large sizes
- unilocular or multilocular
- smooth surface
- fluid filled

9. ENDOMETRIOMA (Chocolate cysts)
MUCINOUS CYSTADENOMA
- May reach very large size
- Filled with thick mucinous material
- Perforation may lead to a serious condition called pseudomyxoma peritonei for which chemotherapy may be needed.
ENDOMETRIOMA (Chocolate cysts)
- Associated with endometriosis

10. DERMOID CYSTS OR BENIGN CYSTIC TERATOMA
- Usually small and may be bilateral
- Contain sebum, hair, teeth etc.
- Contains elements from endoderm
mesoderm and ectoderm
- Can change into malignant teratoma
- Avoid spilling of contents which leads
to chemical peritonitis

11. FIBROMA
- Firm in consistency
* Meigs syndrome
Ovarian fibroma + ascites, hydrothorax
following removal of fibroma, there is spontaneous resolution of ascites and hydrothorax

12. Clinical signs and symptoms of ovarian masses:
1.  abdominal girth
2. Abdominal discomfort
3. Pressure symptoms bladder
bowel
4. Acute abdomen due to
- Hge
- Rupture
- Torsion
5. Asymptomatic coincidentally diagnosed

13. RADIOLOGICAL FEATURES OF BENIGN OVARIAN MASSES:
1. Unilocular
2. Smooth surface
3. No solid elements
4. No external or internal outgrowth
5. No ascites
6. Unilateral
7. Normal doppler flow

14. CLINICAL FEATURES OF BENIGN OVARIAN TUMORS
 Unilateral
 Cystic
 Mobile
 No ascites
 No cul de-sac nodules
 Slow or no growth

15. EVALUATION OF THE PATIENT WITH OVA ADNEXAL MASS.
 Complete Hx and physical exam
 U/S
 CT scan with contract or IVP
 Ba enema or colonoscopy
 Laparoscopy or laparotomy accordingly

16. INDICATIOONS FOR SURGERY
 Ovarian cyst >5 cm followed for wks.
 Solid lesions
 Papillary vegitation
 Mass >10 cm at the time of presentations
 Ascites
 Palpable mass in premenarchal or post menopausal
 Suspicion of torsion or rupture
