Body stalk anomalies are a group of massively disfiguring abdominal wall defects in which the abdominal organs lie outside of the abdominal cavity in a sac of amnioperitoneum with absence of or very small umbilical cord. Various hypotheses proposed to explain the pathogenesis of limb body wall complex include early amnion disruptions, embryonic dysplasia, and vascular disruption in early pregnancy. Body stalk anomaly is an accepted fatal anomaly and, hence, its early diagnosis aids in proper management of the patient.

Background: Gestational age is frequently over or under estimated, as the conventional gestational estimation is based on the last menstrual period and on ultrasonography. Many people are unaware of their last menstrual period and irregular menstruation and ultrasonography is bound to have a bias, thereby posing difficulties in the estimation gestational age. Placental thickness measured at the level of umbilical cord insertion appears to be a new promising parameter for estimation of gestational age of fetus as placenta is a maternal foetal organ and its size is a reflection of the health and size of the foetus. It provides the physiological link between a pregnant woman and the fetus.Measurement of placental thickness is relatively simple and very useful. In our present study we have tried to measure Placental thickness at the level of umbilical cord and determine its relationship with gestational age of foetus in normal singleton pregnancy. Methods: The current crossectional study was conducted at the department of radiodiagnosis, Gandhi medical college and Hamidia hospital, Bhopal from April 2012 to December 2014. This is a hospital based study with a sample size of 199 normal antenatal women. All the subjects were enrolled with detailed oral and written consents. All examinations were performed using GE logic 3 expert scanner with 3.5 MHz convex array transducer. Placental thickness in millimeters was measured at the level of insertion of the umbilical cord. Data was compiled in MS excel sheet and analyzed using online statistical calculator, chi square test and pearson correlation coefficient were applied with value of P <0.05 was considered statistically significant. Results: In the total study group of 199 normal antenatal women, the age ranged between 18yrs to 34 years and the mean age was between 20 and 25 years of age. Anterior placenta was noted to be the most common location amongst the study sample. It is observed that placental thickness correlates with gestational age and gradually increases as gestational age increases. To prove that there was a correlation the between placental thickness and the gestational age, the Pearson correlation coefficient was found to be r = 0.98 and the p value was <0.001, thereby establishing a positive correlation between the two variables, indicating placental thickness measured in millimeters increases with gestational age measured in weeks and were statistically significant. Conclusion: A linear increase in mean placental thickness with gestational age was observed using correlation analysis in our present study conducted to determine the relationship between placental thickness and gestational age. Placental thickness measured in millimeters increases with gestational age from 11 weeks to 37 weeks. Placental thickness can be used as a predictor of the gestational age, in women in whom the last menstrual period is unreliable or is not known. In instances when femoral length was difficult to measure due to excessive foetal movements, Placental thickness was found t...

Thanatophoric dysplasia is the lethal skeletal dysplasia characterized by marked underdevelopment of the skeleton and short-limb dwarfism. Foetus has short neck, narrow thoracic cage and protruberant abdomen. Other anatomical features include a relatively enlarged head with frontal bossing, platyspondyly, telephone handle femurs. Thanatophoric dysplasia is usually diagnosed using second trimester ultrasonography. We report this rare entity from rural India with emphasis on its anatomical features along with review of relevant literature.

Delta phalanx or longitudinal bracketed epiphysis is a rare congenital anomaly that affects phalanges in the hand more commonly than toes. It results from a defective secondary ossification that extends longitudinally along the diaphysis and brackets the diaphysis and metaphysis, causing restricted longitudinal growth and resultant angular deformities. Although rare, longitudinal epiphyseal bracket most commonly manifests in the hands as clinodactyly and in the feet as hallux varus. We report a case of 18 year old male patient with isolated bilateral multiple proximal delta phalanges of hand.

Patau syndrome is the least common and most severe of the viable autosomal trisomies with median survival of fewer than 3 days was first identified as a cytogenetic syndrome in 1960. Patau syndrome is caused by an extra copy of chromosome 13. In this case report, we present antenatal imaging findings & gross foetal specimen correlation of foetus with Patau syndrome confirmed by karyotyping in third gravida who had significant previous obstetric history of gastrochisis in monochorionic and monoamniotic twins who died at 14 weeks of gestation.
