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.

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
In studies of chronic pelvic pain in which
women had hysterectomies, the
incidence of adenomyosis is about 15%
to 25%

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

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.

• there may be uterine enlargement from
about 6-10 weeks pregnancy size
• The uterus can feel soft and boggy on
pelvic exam. Sometimes adenomyosis
is associated with uterine fibroids
(leiomyomata)

repeated bimanual examinations, over
several months, just before and after
menstruation have been recommended
to detect fluctuating changes in contour,
size and consistency of the uterus

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.

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%.

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

Myometrial biopsy laparoscopically

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.

however the same
If an antibody unique to adenomyosis could be
isolated and purified then a highly specific
serum screening test could be developed.

of the lesion's margins and the presence or

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.

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.

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.
