Adenomyosis



Dr. Mohammed Abdalla

Egypt, Domiat G Hospital

definition

Adenomyosis is a benign disease

of the uterus characterized by

ectopic endometrial glands and

stroma within the myometrium

It is associated with myometrial

hypertrophy and may be either

diffuse or focal.

definition

adenomyoma describes a focus of

adenomyosis within a leiomyoma

(fibroid). Both conditions are

common so it is not surprising that

this overlap condition may occur.

definition

The gland tissue grows during the

menstrual cycle and then at

menses tries to slough, the old

tissue and blood cannot escape

This trapping of the blood and tissue

causes uterine pain in the form of

monthly menstrual cramps.

It also produces abnormal uterine

bleeding.

Associated factors

Over 23% of patients requiring hysterectomy for

control of chronic severe pelvic pain had

adenomyosis, and almost half of these

women had had a tubal ligation performed.

The possible relationship of adenomyosis to a

previous tubal ligation has been explored.





Women's Health Center of South Orange County

Associated factors

No relationship was found between age at surgery,

age at menarche, indications for surgery,

menopausal status at intervention, and presence

of adenomyosis.But parity may be associated

with an increased frequency of adenomyosis.







Clinica Ostetrica e Ginecologica Luigi Mangiagalli, Department of Obstetrics and

Gynaecology, University of Milano, Italy

The typical symptoms include



• Pelvic pain,



• Dysmenorrhea,



• And menorrhagia unresponsive to hormonal therapy or uterine

curettage.



• Subfertility.And pregnancy termination.



classic presentation



Cyclic, cramping uterine pain beginning later in reproductive life

(generally after age 35) and often associated with prolonged and

heavy menses

Pelvic pain

women had hysterectomies, the

incidence of adenomyosis is about 15%

2,616 consecutive hysterectomy specimens

examined during a 7-year period.

Adenomyosis was noted in 16%



Multiparas between the ages of 30 and 50 years were

most commonly affected.



Abnormal uterine bleeding was the common symptom



Myohyperplasia and leiomyomas were the usual

associated lesions.



Adenomyosis uteri was seen equally in women of

African, Indian and mixed races in this West Indian

population

(Discepoli S, Leocata P, Giangregorio F).examined

1500 surgical bits had been histologically examined..

In all they have found 310 cases of adenomyosis

(20,6%);

The diagnosis can only be proven by the

pathologists



A good gynecologist may suspect adenomyosis

based on the clinical factors, but the final diagnosis

usually has to wait until hysterectomy is performed.

Hysterography

Hysterography

the presence of ill defined areas of

contrast intravasation extending

perpendicularly from the uterine cavity

into the myometrium isThe most

characteristic feature of adenomyosis

on hysterography.

Unfortunately, the sensitivity of this

technique is too low for clinical practice.



Marshak RH, Eliasoph J. The roentgen findings in

adenomyosis. Radiology 1955; 64:846-51

Hysterography

Filling of cavities in the uterine wall during

hysterography was observed in 54 of 320

surgically excised specimens in which metal

threads had been inserted at different levels

for identification.

Adenomyosis may have accounted for these

cavities in 24%.





Radiological Society of North America ,

Radiology, Vol 118, 581-586,1976

Hysterography

True adenomyomas (encapsulated) are

uncommon tumors of the uterus. At

hysterosalpingography, detection of a

network of fine channels in a very well-

circumscribed area of the myometrium,

connected with the uterine cavity, allows a

preoperative diagnosis

Myometrial biopsy laparoscopically

or sonographically guided

Myometrial biopsy laparoscopically

or sonographically guided

a larger study by Popp et al. who took not only

needle biopsies immediately after

hysterectomy but also at the time of

laparoscopy as well as transvaginally under

ultrasound guidance A single myometrial

biopsy picked up only 8% to 19% of women

with adenomyosis. The sensitivity of random

needle biopsy is therefore too low for clinical

practice.

CA 125

CA 125 antigens present on adenomyotic

epithelial cells have a different molecular

mass from those present on eutopic

endometrium; the antibody binding site is

however the same

If an antibody unique to adenomyosis could be

isolated and purified then a highly specific

serum screening test could be developed.

Transvaginal ultrasonography in the

differential diagnosis of adenomyoma versus

leiomyoma



Transvaginal ultrasonography is an

effective, noninvasive, and relatively

inexpensive procedure for the

preoperative differential diagnosis of

adenomyoma versus leiomyoma.

versus leiomyoma

Transvaginal sonography is an effective

procedure for the preoperative differentiation

of adenomyoma from leiomyoma. If the status

of the lesion's margins and the presence or

absence of hypoechoic lacunae were

selected for analysis, leiomyomas could be

correctly diagnosed with transvaginal

sonography in 95% of cases.

MRI

MRI

• MRI should be expected to be excellent in

recognizing uterine masses like fibroids, cysts, and

adenomyomas if they reach 5 mm. or greater in

size. MRI may be able to lead us to expect

adenomyosis if the myometrial thickness is

increased or the consistency of the myometrium is

changed.

MRI

Magnetic resonance imaging was

superior to TVS for the diagnosis

of adenomyosis.

Magnetic resonance imaging had

a higher specificity than TVS, but

their sensitivities were in line.

MRI

On T2-weighted MRI, focal adenomyosis

are seen in areas of abnormal low signal

intensity within the myometrium in

approximately 50% of patients. These foci

correspond to islands of heterotopic

endometrial tissue, cystic dilatation of

heterotopic glands, or hemorrhagic foci.

MRI

On T2-weighted MRI, diffuse adenomyosis

usually manifested as diffuse thickening of

the junctional zone with homogeneous low

signal intensity .T2-weighted imaging

provided significantly better lesion detection

than unenhanced or contrast material–

enhanced T1-weighted imaging

Sagittal T1-weighted MR image shows a mildly

enlarged anteverted uterus. The junctional zone

is isointense relative to the myometrium.

Sagittal T2-weighted MR image shows diffuse, even

thickening of the junctional zone (arrows), a finding

consistent with diffuse adenomyosis

Extensive involvement of diffuse adenomyosis in a 42-

year-old woman. Sagittal T2-weighted MR image

demonstrates diffuse areas of low signal intensity involving

most of the uterus (straight arrows) and punctate high-

signal-intensity foci (arrowhead). A few small nabothian

cysts (curved arrows) are seen in the uterine cervix.

MANEGMENT

MANEGMENT



The only definitive treatment for

adenomyosis is total hysterectomy,

with or without ovarian conservation.

Gonadotropin releasing hormone agonists in the

treatment of adenomyosis with infertility







(1) GnRH- agonists is efficient in reducing the

adenomyotic uterine size, and may facilitate fertility.

(2) For ademyomata associated with infertility, GnRH-

alpha therapy may avoid the risk of rupture of uterus

which may occur after adenomyomectomy

pregnancy.

(3) For infertility, GnRH-alpha treatment before

laparoscopic surgery greatly decreases surgical

difficulties and blood loss in certain cases.

conservative surgery for adenomyosis



The conservative surgery for adenomyoma

can reduce symptom and raise pregnancy

rate significantly, it can be accepted by

young women who want to preserve their

reproductive capacity.

Though the pregnancy rate of conservative

surgery for diffused adenomyosis was low,

it still has therapeutic value

Uterine arterial embolization in the

treatment of adenomyosis



UAE procedures were performed in 23 patients with

adenomyosis. After treatment the symptoms and uterine

volume of all patients were investigated.



All clinical symptoms of 23 patients relieved.

•Dysmenorrhea completely disappeared in 19 patients, significantly alleviated

in 2 patients. But in other 2 recurred.

•The uterine volume shrunk significantly [(50 +/- 18)%] vs [(100 +/- 0)%].

•The blood flow within the uterine and lesions detect by color doppler flow

imaging decreased immediately after UAE.

•Low-abdominal pain and slight fever were seen after treatment and

recovered within 1 - 2 weeks.

UAE is an effective and safe

method in the treatment of

adenomyosis.

BUT the recurrence rate is not

yet evaluated.
