This is an ultrasound of the pelvis
0:02
in a patient with a positive home
0:03
pregnancy test presenting with left lower
0:06
quadrant abdominal pain and tachycardia.
0:09
We have transabdominal images of the pelvis
0:12
and a long view or sagittal view of the uterus.
0:15
As we evaluate the endometrial cavity, we see
0:18
the hyperechoic endometrial stripe without
0:21
a visible intrauterine gestational sac.
0:25
Additional transverse plane images of the
0:27
uterus again demonstrate normal myometrium
0:30
and a hyperechoic endometrial stripe.
0:32
Endometrium without a gestational sac visible.
0:36
The right ovary is identified on transabdominal
0:39
imaging and is normal in size and appearance.
0:42
In the left adnexa, posterior and lateral
0:45
to the uterus, which is located here,
0:48
there is a heterogeneously hyperechoic
0:51
and hypoechoic mass measuring at least 6.1 centimeters.
0:54
21 00:00:56,680 --> 00:00:58,099 Within the mass, we can see a
0:58
discrete hyperechoic ring-like
1:01
structure with central heterogeneity.
1:04
Evaluation of the upper abdominal
1:06
quadrants demonstrates significant free
1:09
fluid adjacent to the right kidney.
1:12
Transvaginal images of the pelvis at the level
1:14
of the uterus and cervix also demonstrate
1:17
significant free fluid in the cul-de-sac.
1:20
It can be noted that the endometrium is
1:22
thickened without a gestational sac present.
1:26
Transvaginal ultrasound images of the
1:28
heterogeneous left adnexal mass again
1:31
demonstrate heterogeneously hypoechoic tissue.
1:35
With a peripherally hyperechoic
1:37
structure with central hypoechogenicity.
1:41
Lace-like echoes and free fluid are seen
1:44
adjacent to the mass in the left adnexa,
1:47
suggestive of clotted blood products.
1:50
On these color Doppler transvaginal images
1:53
of the left adnexa, we again see the lesion,
1:56
which is a ring-like hyperechoic structure
1:58
with intense peripheral vascularity.
2:01
This is known as the ring of fire sign.
2:05
This is an additional transvaginal
2:06
ultrasound image of the left adnexa, where
2:09
we see a ring-like hypoechoic structure
2:11
with central hypoechoic components.
2:15
Lastly, these are transverse transvaginal
2:18
images of the uterus from inferior to superior.
2:22
We can see that surrounding the uterus
2:24
there's a significant amount of free fluid.
2:26
I want to point out the
2:27
appearance of the fluid here.
2:29
This is not just simple fluid, right?
2:31
Simple fluid in the pelvis looks
2:33
anechoic and would be darker than this.
2:36
Anytime you see free fluid in the pelvis
2:38
that looks like it's a handful of sand that's
2:41
been dumped into a jar of water and shaken up.
2:44
This grainy, slightly hyperechoic
2:46
appearance, these are blood products.
2:48
So this patient has a significant
2:50
amount of pelvic hemoperitoneum.
2:53
To summarize, we have a ring-like,
2:55
hypervascular structure in the left adnexa
2:57
with adjacent clotted blood products and
2:59
significant abdominal pelvic hemoperitoneum.
3:03
This patient was taken to surgery and
3:04
a diagnosis of ruptured left tubal
3:07
ectopic pregnancy was confirmed.
