GYNAECOLOGY:🔵🔵
Bagel sign:
Ultrasonographic sign. Gestational
sac in the adnexa with hyperechoic
ring
Ball Sign:
Radiological sign of intrauterine
fetal death. X-ray shows crumpled
up spine of the fetus..
Banana Sign:
Ultrasound sign in open spina
bifida. Shows abnormal anterior
curvature of cerebellum. Due to the
associated Arnold-Chiari
malformation.
Chadwick’s Sign:
Bluish hue to the vestibule and
anterior vaginal wall. Seen in first
trimester of pregnancy. Cause is
increased blood flow to the pelvic
organs. Also known as jacquemier’s
Sign.
Cullen Sign:
Bluish discoloration of skin around
umbilicus. Occurs due to intra
peritonealhemorrhage. Seen in
ruptured ectopic pregnancy.
Double Bubble Sign:.
Useful in prenatal diagnosis of
duodenal atresia. Duodenal atresia
usually presents with
polyhydramnios and produces
dilatation of stomach and first part
of duodenum
Double decidual sac Sign:
Normal Ultrasonographic
appearance of intrauterine
gestational sac. Seen as
twoconcentric echogenic rings
separated by a hyperechoic space.
Goodell Sign:
Marked softening of the cervix in
contrast to non pregnant state.
Also due toincreased blood flow.
Hegar Sign:
An indication of Pregnancy.
Softening of the lower parts of the
uterus enablesapproximation of
vaginal and abdominal fingers in
bimanual pelvic examination.
Vaginalfingers are placed in the
posterior fornix and abdominal
hand pressed down behind
theuterus.
Jacquemier’s sign: Refer
Chadwick
SignKustner’s Sign:
Sign of placental separation. On
pushing the uterus upwards does
not move thecord with it due to
the separation.
Ladin’s Sign:
Softening in the midline of the
uterus anteriorly at the junction of
the uterus andcervix. It occurs at
about 6 weeks gestation
Lambda Sign:
Ultrasonographic sign seen in
dichorionic pregnancies. Due to
the chorionic tissuein between the
two layers of the membrane
between the twins.
Lemon Sign:
Ultrasound sign in open spina
bifida. Shows abnormal anterior
curvature of cerebellum. Due to the
associated Arnold-Chiari
malformation.
Osiander’s Sign:
Pulsations in the lateral fornix due
to the increased vascularity.
Palmer’s Sign:
Regular rhythmic contractions of
uterus felt as early as 6-8 weeks .
It is a sign of pregnancy.
Piskacek’s Sign:
Asymmetric growth occurs to the
uterus in initial stages of
pregnancy due to thelateral
implantation of the blastocyst. The
area of implantation feels soft
compared tothe other parts.
Robert’s Sign:
Radiological sign of intrauterine
fetal death. X-ray shows presence
of gas in thefetal great vessels.
Earliest radiological sign of
intrauterine fetal death
Schroder’s Sign:
A sign of placental separation.
Uterus rises up when the
separated placenta ispassed
downwards.
Spalding Sign:
Sign of intrauterine fetal death.
Overlapping of skull bones after
fetal demise.Observed by
ultrasonogrm.
Stallworthy’s Sign:
Slowing of fetal heart rate on
pressing the head down I to the
pelvis and promptrecovery on
release of pressure is termed
Stallworthy’s sign. This sign is
suggestive of posterior placenta
praevia.
Stuck Twin Sign:
Seen in twin to twin transfusion
syndrome. Due to the severe
oligohydramniossmaller twin is
held in a fixed position along the
uterine wall. This is called stuck
twinsign.
‘T’ Sign:
Ultrasonographic sign seen in
monochromic twins. As the
intertwin membranedoes not have any chorionic tissue it gives rise to ‘T’ sign in ultrasound
