The nomogram of prenasal thickness and nasal bone ratio and its relationship with nuchal fold in second-trimester fetal ultrasound.

AIM: We aimed to define the normal values of second-trimester fetal prenasal thickness and nasal bone length ratio (PNT/NBL) in a low-risk Turkish population and investigate the relationship between the increased PNT and nuchal fold (NF). METHOD: We retrospectively reviewed the data of 650 cases considered to be euploid fetuses who presented to our clinic between December 2013 and September 2014 for a second-line ultrasound between 17 and 24 weeks. Their PNT, NBL, NF and biometric (BPD, HC, AC, FL and HL) measurements were recorded. RESULTS: A total of 650 cases considered to be euploid fetuses were included in this study. There was a linear increase in PNT with the gestational weeks (mean value 3.01 at weeks 17-18 and 3.76 at weeks 23-24). The PNT/NB ratio showed a slight decrease in advancing gestational weeks (mean value 0.57 at weeks 17-18 and 0.50 at weeks 23-24). The 95th percentile value of the PNT/NB ratio, independent of the gestational week, was 0.76. The values of both PNT and NF increased with advancing gestational weeks, but there was no statistically linear increase between PNT and NF (R2 : 0.115). CONCLUSION: In this study, we provided a nomogram of the PNT/NB ratio. Both NF thickness and PNT should be dealt with as two separate markers. Although the formation mechanisms are thought to be the same in both of them, a strong linear relationship does not exist between them.

Is the presence of corpus callosum predictable in the first trimester?

Corpus callosum agenesis (CCA) is a clinical condition accompanied by various aneuploidy and genetic syndromes. We identified the development of the corpus callosum (CC) in 278 patients before 18 weeks of gestational age by visualising the pericallosal artery (PCA) in the callosal sulcus and changes in the lengths and ratios of the midbrain (MB) and falx (F), which suggested elevation of the third ventricle and thalamus due to CCA in the first trimester. We succeeded in visualising the path of the PCA in 273 patients. As expected, we observed an increase in the lengths of the MB and F throughout the pregnancies. The MB:F ratio was 0.5-0.6, and it was independent of gestational age. In all 278 patients, the MB:F ratio was <0.6 (95th percentile = 0.79). We observed the presence of the CC during anatomical screening at gestational weeks 18-24. Visualisation of the PCA path (98% sensitivity) and calculation of the MB:F ratio <95th percentile (0.79-100% sensitivity) had very high sensitivity that indirectly confirmed the presence of the CC in the first trimester of pregnancy. Impact statement What is already known on this subject: After reading the articles for detecting the absence of corpus callosum (CC) at first trimester with midbrain (MB) and falx (F) measurement by Lachmann et al. ( 2013 ) and visualising pericallosal artery (PCA) as an indirect sign of CC agenesis by Pati et al. ( 2012 ), we aimed to have a look for our records visualising PCA in callosal sulcus and measure MB-F, as well as their ratios for an indirect sign of 'presence' of CC at first trimester. What the results of this study add: In recent literature, it is not possible to find many articles suggesting the presence of CC between 11 and 13 weeks of gestation. Díaz-Guerrero et al. ( 2013 ) and Pati et al. ( 2012 ) has researched visualising PCA path. Lachmann et al. ( 2013 ) reported an article for MB and F measurements in early suspicion of CC agenesis. Our study will be the first article in visualising PCA path and measuring MB-F lengths as well as their ratios for 'presence' of CC with high sensitivity rates (98% and 100%). What are the implications of these findings for clinical practice and/or further research: This study encourages clinicians visualising PCA path and measure MB-F lengths when they will try to visualise repetitive times and see how it is an easy procedure when you get used to it.

Is primiparity a risk factor for advanced maternal age pregnancies?

OBJECTIVE: Currently, more women are delaying childbearing until their 40s.This study compared the pregnancy and maternal features, pregnancy and foetal outcomes between multiparous and primiparous patients. We compared the same factors between assisted reproductive technology (ART) and non-ART primiparous patients because of the high proportion of ART used in the primiparous patients. METHODS: The study retrospectively examined 1680 patients, 35 years of age and older, between March 2008 and February 2015. RESULTS: Comparing the features of these two groups, there was an increased incidence of employment and the use of ART in primiparous patients, while birthweight tended to be higher in the multiparous group. There were no significant differences in pregnancy complications other than hypertension disorders, such as pre-eclampsia and HELLP syndrome, which were significantly more frequent in primiparous patients. The rates of foetal growth retardation and perinatal death were significantly higher in primiparous women. Comparison of the data between ART and non-ART primiparous patients indicated that the ART group had a higher initial body mass index and a lower smoking rate. No significant differences in pregnancy complications or foetal outcome were observed between these two groups. CONCLUSION: Primiparity is associated with increased pregnancy and foetal complications in advanced age pregnancies. However, the use of ART in this age group does not seem to be an additional risk factor.

Prophylactic red blood cell exchange may be beneficial in the management of sickle cell disease in pregnancy.

BACKGROUND: Sickle cell disease (SCD) is associated with chronic hemolysis and painful episodes. Pregnancy accelerates sickle cell complications, including prepartum and postpartum vasoocclusive crisis, pulmonary complications, and preeclampsia or eclampsia. Fetal complications include preterm birth and its associated risks, intrauterine growth restriction, and a high rate of perinatal mortality. The purpose of this study was to evaluate pregnancy outcomes in patients with SCD who underwent planned preventive red blood cell exchange (RBCX). STUDY DESIGN AND METHODS: We retrospectively evaluated the complications of SCD in 37 pregnant patients. Patients with SCD who had undergone prophylactic RBCX were compared with a control group who had not undergone RBCX during pregnancy. RESULTS: Forty-three exchange procedures were performed in 24 patients. The control group comprised 13 patients with a mean age of 27.4 ± 3.3 years who had not undergone RBCX during pregnancy. Four of the five patients who developed a vasoocclusive crisis died. There was a significant difference in maternal mortality between the study and control groups (p = 0.011). There was also a significant difference in the incidence of vasoocclusive crisis between the study and control groups. One fetal death occurred in the 20th gestational week in a patient in the control group, although there were no postpartum complications in either the babies or the mothers in the control group. CONCLUSION: This study has demonstrated that prophylactic RBCX during pregnancy is a feasible and safe procedure for prevention of complications. Given the decrease in the risks of transfusion, RBCX warrants further study.

Transvaginal ultrasound-guided local methotrexate administration as the first-line treatment for cesarean scar pregnancy: Follow-up of 18 cases.

Cesarean scar pregnancy (CSP) is a rare type of ectopic pregnancy, which occurs in previous cesarean section scar tissue, with an incidence of 1 in 1800-3000 pregnancies. Transvaginal ultrasound-guided local methotrexate (MTX) administration presents as a non-systemic option with possible better penetration to the pregnancy site. We present the management of 18 patients with CSP solely by transvaginal ultrasound-guided local MTX administration. All patients were treated with local MTX with a dose of 50 mg/m(2) . Eleven (61.1%) of the patients did not need any further intervention. Four patients (22.2%) were treated with additional single-dose systemic MTX due to inadequate alteration in blood ß-human chorionic gonadotrophin levels. Three patients (16.7%) required hysteroscopy and/or laparotomy. We suggest that transvaginal ultrasound-guided local MTX treatment may be considered as a first-line treatment for CSP.

The impact of sweeping the membranes on cervical length and labor: a randomized clinical trial.

OBJECTIVES: The aim of the study was to investigate to what extent sweeping of the membranes contributes to cervical shortening and if cervical shortening is related to the time to onset of labor and duration of the active phase of labor METHODS: This prospective randomized clinical trial was performed at Baskent University between February and March 2011. Women were randomly assigned to receive membrane sweeping (Sweeping Group) (n = 69) or no membrane sweeping (Control Group) (n = 71). Cervical length was measured (cervix1) in both groups by examiner 1 and the Bishop Score was determined in the control group and sweeping was performed in the sweeping group by examiner 2. Two days later the patients had another cervical length measurement (cervix 2) by examiner 1, blinded to the group and results of the examiner 2. t test, Mann-Whitney U test and Chi-square test were used for statistical analyses. RESULTS: Cervix 1 was 27.4 +/- 8.4 mm and 29.6 +/- 8.9 mm (p = 0.14), cervix 2 was 23.3 +/- 8.8 mm and 23.8 +/- 8.5 mm (p = 0.28) and cervical shortening was 5 +/- 4 mm and 5 +/-4 mm (p = 0.446), time to onset of labor was 6.3 +/- 4.6 and 5.7 +/- 4.7 (p = 0.38) and duration of labor was 5.8 +/- 2.89 and 5.7 +/- 2.4 (p = 0.82) for the sweeping and the control groups, respectively CONCLUSIONS: Sweeping of the membranes does not reduce cervical length and does not shorten time to onset of labor and duration of the active phase of labor NCT 1309308: Sweeping the Membranes, Cervical Length and Duration of Labor

Does bleeding affect fetal Doppler parameters during genetic amniocentesis?

OBJECTIVE: The aim of this study was to investigate the relationship between fetal Doppler parameters and bleeding at insertion points during amniocentesis. MATERIAL AND METHODS: This prospective study was conducted between July 2010 and February 2011. A total of 215 amniocentesis procedures were performed during this period. Five patients with Down syndrome were excluded from the study. The remaining 210 patients were divided into Group 1 (bleeding at insertion site) and Group 2 as a control group. One needle type was used for all patients. Umbilical artery resistance index (UARI), umbilical artery pulsatility index (UAPI), middle cerebral artery resistance index (MCARI), middle cerebral artery pulsatility index (MCA PI), and middle cerebral artery peak systolic velocity (MCAPSV) were measured immediately and before and after amniocentesis. RESULTS: Bleeding at the insertion point during amniocentesis did not significantly change the UARI (34% increase for Group 1 and 46.5% increase for Group 2, p=0.238), the MCARI (52% increase for Group 1 and 45% increase for Group 2, p=0.622), or the MCAPSV (37% increase for Group 1 and 49% increase for Group 2, p=0.199). UARI, MCARI, MCA PI, and MCAPSV were not significantly altered following amniocentesis in Groups 1 and 2. There was a significant increase in UAPI following amniocentesis only in Group 2. CONCLUSION: Bleeding during genetic amniocentesis did not change umbilical artery and middle cerebral artery Doppler parameters.

First trimester maternal lipid levels and serum markers of small- and large-for-gestational age infants.

OBJECTIVE: To investigate if first trimester lipids, sonographic parameters and serum markers are related to small- and large-for-gestational age (SGA, LGA) infants. METHODS: This study was conducted at Baskent University Adana Research Center between December 2009 and July 2011 and enrolled 433 women. Blood samples were drawn to measure fasting blood glucose, serum triglycerides, cholesterol, very low-density lipoprotein, low-density lipoprotein, high-density lipoprotein, fß-hCG and pregnancy associated protein-A (PAPP-A) at the first trimester. Crown rump length and nuchal translucency were measured as suggested by the fetal medicine foundation. RESULTS: LGA group was significantly taller (p = 0.016) and SGA group had significantly greater BMI (0.025). SGA fetuses were born at a significantly earlier gestational age (p = 0.001). Univariate analysis revealed that LGA group had significantly lower cholesterol (p = 0.038) and LDL levels (p = 0.041). PAPP-A was significantly lower in SGA Group compared with LGA Group (0.027). After controlling for age, parity, height, pre-pregnant BMI, weight gain during pregnancy and fasting blood sugar, none of the lipids, serum markers or sonographic parameters was related to LGA. PAPP-A was the only parameter significantly associated with SGA after multivariate analysis (p = 0.008). CONCLUSION: PAPP-A was significantly associated with SGA after controlling for confounders.

Obstetrical complications associated with first-trimester screening markers in twin pregnancies.

AIM: The aim of this retrospective study was to investigate the relation between perinatal complications in twin pregnancies and the combination of first-trimester maternal serum pregnancy-associated plasma protein-A (PAPP-A) and free beta-human chorionic gonadotrophin (ß-hCG) levels. MATERIAL AND METHODS: The study was conducted at the Perinatology Department of Baskent University between January 2005 and December 2011. In total, 104 patients with twin pregnancies were recruited. The association of first-trimester maternal serum-screening markers with perinatal complications was investigated for small-for-gestational-age (SGA) fetuses or intrauterine growth restriction (IUGR), preterm delivery (before 34 weeks of gestation), pregnancy-induced hypertension (PIH), and growth discordance between fetuses. RESULTS: Low serum PAPP-A (below 10th percentile) levels were not correlated with preterm labor, PIH, or IUGR in twin gestations. Elevated free ß-hCG levels (>90th percentile) were linked to increased rates of PIH and small-for-gestational-age fetuses or IUGR. CONCLUSION: Elevated first-trimester free ß-hCG was related to adverse pregnancy outcomes in twin pregnancies, whereas low PAPP-A levels were not linked to adverse pregnancy outcomes.

Comparison of intrathecal levobupivacaine combined with sufentanil, fentanyl, or placebo for elective caesarean section: a prospective, randomized, double-blind, controlled study.

BACKGROUND: The addition of opioids to local anesthetics contributes to the quality of spinal anesthesia and postoperative analgesia. OBJECTIVE: In our prospective, randomized, double-blind, controlled study, our aim was to compare the effect of low-dose sufentanil plus levobupivacaine or a fentanyl plus levobupivacaine mixture on anesthesia quality, block characteristics, newborn and mother well-being, surgeon satisfaction, and duration of postoperative analgesia. METHODS: Ninety-three patients were randomized into 3 groups (n = 31). Patients in Group C received 0.5% levobupivacaine (2.2 ± 0.2 mL), Group S received 2.5 µg sufentanil plus 0.5% levobupivacaine (2.2 ± 0.2 mL), and Group F received 10 µg fentanyl plus 0.5% levobupivacaine (2.2 ± 0.2 mL) intrathecally completed to a volume of 3 mL with the addition of saline in all groups. Patients' demographics, sensory and motor block characteristics, hemodynamics, Apgar scores, umbilical blood gas values, maternal side effects, surgeon satisfaction score, time to first analgesia requirement, and additional analgesic use within 24 hours were recorded. RESULTS: In Group S and Group F, target levels of sensory and motor block were achieved more rapidly (P < 0.001). The hemodynamic values were lower (P < 0.05), and the duration of sensory blockade and the time of first analgesic requirement were longer (P < 0.001) in Group S. Additional analgesic requirement during first 24-hour period was lowest in Group S, and highest in Group C (P < 0.001). Apgar scores and umbilical blood gas samples were similar between groups. Postoperative pruritus was more frequent in Group S (P < 0.001) and surgeon satisfaction score was significantly lower in Group C (P = 0.003). CONCLUSIONS: We suggest that the addition of sufentanil and fentanyl to intrathecal levobupivacaine during caesarean section surgery is more effective than the administration of levobupivacaine alone. The addition of sufentanil to levobupivacaine allowed rapid onset time for sensory and motor block levels. It also extended the duration of postoperative analgesia and led to a decrease in total analgesic requirement. ClinicalTrials.gov identifier: NCT01858090.

Fetal axillary cystic hygroma: a novel association with triple X syndrome.

BACKGROUND: Triple X syndrome is a relatively common sex chromosomal aneuploidy with an estimated incidence of one in every 1000 female births. There is considerable diversity in phenotypes among patients with triple X syndrome. Triple X syndrome has been shown to have associated abnormalities, with genitourinary malformations being the most consistent. Cystic hygroma (CH) is a lymphatic malformation that occurs because of the lack of development of communication between the lymphatic and the venous systems. CH has an incidence of 1 in every 6000-10,000 live births. CH is associated with a variety of conditions, including chromosomal aneuploidies and fetal malformations. CASE: We report a case of prenatally detected triple X syndrome with axillary CH as an isolated finding. The patient was referred because of a fetal cystic mass at the right axillary region. Amniocentesis revealed 47,XXX karyotype, and no additional abnormalities were detected prenatally or after abortion. CONCLUSION: This is a novel description of axillary CH associated with triple X syndrome.

Do intrauterine growth restricted fetuses of the hypertensive and normotensive mothers differ from each other?

PURPOSE: To investigate if normotensive and hypertensive patients with intrauterine growth restricted (IUGR) fetuses were different with respect to maternal and fetal characteristics and Doppler flow. METHODS: The records of patients with IUGR fetuses who had to be delivered before 34th gestational week because of fetal distress were examined. Early Doppler abnormalities were defined as increased umbilical artery resistance and redistribution of blood flow in the middle cerebral artery while late Doppler abnormalities were defined as the absence or reversal of umbilical artery blood flow and Doppler flow changes in venous Doppler. t Test, Chi-square test and Mann-Whitney U test were used for the comparison of data as appropriate. p < 0.05 was considered statistically significant. RESULTS: Thirty-six patients were hypertensive while 42 were normotensive. Gestational week at admission for hypertensive and normotensive groups (30.8 ± 3.6 vs. 32.3 ± 3.1) (p = 0.057), time to delivery (7.1 ± 12.6 vs. 4.3 ± 9.1 days) (p = 0.267) and gestational week at delivery (31.8 ± 3.1 vs. 32.9 ± 2.9) (p = 0.117) were similar. Birth weight was significantly lower (1242 ± 534 vs. 1516 ± 504 g) (p = 0.02) in the normotensive group. The frequency of having oligohydramnios (64.2 % for normotensive and 44.4 % for hypertensive patients) (p = 0.079) was similar in both groups. Early Doppler abnormalities were more common in hypertensive group (75 vs. 40.5 %) (p = 0.001) while late Doppler abnormalities were more common in normotensive group (25 vs. 59.5 %) (p = 0.001). CONCLUSION: Birth weight was lower and late Doppler abnormalities were more common in the normotensive group while early Doppler abnormalities were more common in hypertensive group.

Transient hydrops fetalis in a prenatally diagnosed pentasomy X?

Numerical abnormalities of sex chromosomes are seen approximately 1 in 400 live births. Pentasomy X is a very rare chromosomal abnormality and it is defined as presence of five X chromosomes instead of two. Prenatal sonographic features have rarely been described in the literature before. Here we present a non-immune fetal hydrops diagnosed during the 17th week of gestation. Ultrasonographic examination revealed subcutaneous edema, pleural effusion and ascites, and also clinodactyly of the fifth fingers of both hands. The fetal karyotype was assessed as 49,XXXXX (pentasomy X) in two different culture flasks. Hydropic signs regressed at 21 weeks' gestation. Prenatal diagnosis may not be possible usually for this rare chromosomal abnormality. Every anomaly detected prenatally, such as transient hydrops, may help us to diagnose pentasomy X.

Comparison of uterine artery Doppler in pregnant women with thrombophilia treated by LMWHs and without thrombophilia.

OBJECTIVE: The aim of this study was to use uterine artery Doppler ultrasonography to investigate the cases of women with thrombophilia who used LMWH during the 18-22-week period of gestation. METHODS: This retrospective study was conducted at our university between January 2005 and July 2010. 64 patients were treated with low-dose LMWHs (enoxaparine 40 mg) from the beginning of pregnancy until 36 weeks of gestation. Fifty control subjects were also included in this study. Transabdominal ultrasound examination and bilateral uterine artery Doppler measurements pulsatility index (PI), resistive index (RI), and systole/diastole measurement (S/D) were performed during the 18-22-weeks period of gestation. RESULTS: No significant differences were found between the groups with respect to maternal age or gestational age at the time of uterine artery Doppler. However, the mean PI (1.07 ± 0.46 for LMWH group and 0.91 ± 0.31 for control, p = 0.036) and the mean RI (0.59 ± 0.12 for LMWH group and 0.54 ± 0.10 for control, p = 0.021) were significantly higher in the trombophilia group. CONCLUSION: Women with trombophilia still have an increased mean PI and RI, as determined by uterine artery Doppler ultrasonography during the 18-22-week period of gestation, even if they use LMWH.

Prenatal diagnosis of right diaphragmatic eventration associated with fetal hydrops.

Congenital diaphragmatic eventration (CDE) is a rare diaphragmatic abnormality. Clinical manifestations of CDE may mimic congenital diaphragmatic hernia. Prenatal differential diagnosis of eventration is critical because postnatal managing and prognosis of these conditions vary significantly. Sonographic features of CDE involve presence of abdominal organs in the thorax, shift of cardiac axis and mediastinum. Non-immune hydrops fetalis (NIHF) has been previously reported to be associated with intrathoracic masses as well as CDE. In this report, we present a case of congenital right diaphragmatic eventration associated with NIHF.

Can the 50-g glucose challenge test be important for subsequent pregnancies?

AIM: Our aim in this study was to examine the risk factors associated with gestational diabetes mellitus (GDM) in women who did not have GDM during a previous pregnancy. MATERIALS AND METHODS: In this retrospective cohort study, we reviewed the charts of all pregnant women who delivered two pregnancies between January 2000 and June 2010. Group 1 consisted of patients with gestational diabetes and Group 2 served as the control. RESULTS: There were 743 women who underwent GDM screening by means of the 50-g glucose challenge test (GCT). Thirty-eight women (5.1%) were excluded because of a previous history of GDM. The recurrence of GDM was 42.1% in this group (16 of the 38). The remaining 705 patients were divided into the GDM group (n = 38) and the control group (n = 667). Undergoing a 50-g GCT during the previous pregnancy (p = 0.000, 95% CI +0.01 to +0.002), age (p = 0.009, 95% CI +0.001 to +0.009), and weight differences between the pregnancies at the first trimester (p = 0.005, 95% CI +0.001 to +0.007) were independent parameters related to GDM. CONCLUSION: The 50-g GCT during the previous pregnancy was, interestingly, increased in the GDM group. It was also an independent risk factor for women without a history of GDM.

Pregnancy-related peritoneal ectopic decidua (deciduosis): morphological and clinical evaluation.

OBJECTIVE: Ectopic decidual reaction (deciduosis) can be seen rarely on the peritoneum during laparotomy for a cesarean section for pregnancy, in addition to the ovary and cervix. The aim of this study was to evaluate the clinical, histopathological, immunohistochemical characteristics of ectopic decidua cases that were incidentally found in the peritoneum during a cesarean section. MATERIAL AND METHOD: A total of seven cases where decidualization was found in the peritoneal biopsy taken during pregnancy at the Baskent University Medical Faculty Adana Teaching and Training Hospital Department of Pathology were included in this study. The clinical features of the cases were obtained from their clinical folders. The morphological findings were recorded and the peritoneal biopsies were analyzed with keratin Pan Ab-1, calretinin, vimentin, HMB-45 and progesterone receptor antibody for immunohistochemical analysis. RESULTS: The mean age for the seven cases was 36±4.16. The gestational age was 33 to 39 (mean 37.2) weeks. Microscopic evaluation revealed decidualized cells that were large polygonal and eosinophilic, some with vacuolated cytoplasm, that formed small nodules under the mesothelium of the peritoneum in all cases. Immunohistochemical staining showed positive staining of the cell cytoplasm with vimentin and positive staining of the cell nucleus with the progesterone receptor antibody in the decidual cells. Calretinin, keratin and HMB-45 stains were negative. CONCLUSION: Pregnancy-related peritoneal deciduosis develops with the effect of progesterone in pregnancy. It disappears without complication in the postpartum period. Immunohistochemistry may help the differential diagnosis of peritoneal deciduosis where problems are experienced differentiating the case from malignant mesothelioma or metastatic tumor.

Joubert syndrome and related disorders, prenatal diagnosis with ultrasound and magnetic resonance imaging.

Joubert syndrome (JBTS) is an autosomal recessive disorder characterized by intellectual disability, hypotonia, ataxia, tachypnea/apnea, and abnormal eye movements. A pathognomonic midbrain-hindbrain malformation seen on cranial magnetic resonance imaging (MRI), which consists of hypoplasia of the midline cerebellar vermis that resembles the cross-section through a molar tooth, has been described previously. The molar tooth sign is defined by a peculiar appearance resembling a molar tooth secondary to an abnormally deep interpeduncular fossa and enlarged superior cerebellar peduncles on axial images at the pontomesencephalic level. The term Joubert Syndrome and Related Disorders (JSRD) has recently been adopted to describe all disorders presenting the "molar tooth sign" (MTS) on brain imaging. JSRD is characterized by lack of decussation of the superior cerebellar peduncles, central pontine tracts and corticospinal tracts suggesting defective axon guidance. Prenatal sonographic findings in fetuses with JSRD are relatively nonspecific and include increased nuchal translucency, enlarged cisterna magna, cerebellar vermian agenesis, occipital encephalocele, ventriculomegaly and polydactyly. We report a case of JSRD detected prenatally at 23 weeks of gestation. The fetus in the present case had a normal karyotype. Sonographic features of the fetus included polydactyly, partial vermian hypoplasia, dilated 4(th) ventricle and mild ventriculomegaly which were also confirmed by prenatal MRI. MTS was demonstrated in a postnatal MRI after pregnancy termination.

A pericardial hydatid cyst and pregnancy.

A cardiac hydatid cyst in pregnancy is a very rare condition. Surgical intervention followed by medical therapy is the treatment of choice. A hydatid disease in pregnancy is challenging with a varied presentation and manifestation. A pregnant woman presented with a ruptured pericardial cyst diagnosed by echocardiography, magnetic resonance and serology. Finally, she received medical treatment and no surgical intervention.
