Background: The zygote of twins implants themselves separately and on different spots in the uterine endometrium. However, the growth of fetal membranes may be collective or singly. There is little data from sonographic view of assessment on the exact progression at different stages of gestation.

Ultrasound shape of the crania was seen by measuring a frozen sonogram of the Biparietal Diameter (BPD) and Cranial Index (CI). The objective aims to report the value of prenatal ultrasound in identifying acute frontotemporal depression. Also, to review specific developmental skull anatomy as it relates to the formation of cranial and fontanelle anomaly. Little data exists on the prevalence of this rare heterogeneous condition; 1 in 3,600 live births with genetic or hereditary factors responsible for most cases. The report in question was observed under routine ultrasound at 26 weeks gestation. Better understanding of fetal skull development (through sonar), and calvaric sutures will further help sonologists in evaluation of fetal brain. Ongoing research developments can be used to further evaluate cranial 'osteo' development as a consequence of synchondrosis and multiple suture unity.

Renal ectopia anatomically results from altered migration of kidneys to their normal position in the lumbar region. Few case reports have been reported in literature. Visceral-tissue variation was in form of quadratus lumborum and psoas major in place of the RT kidney. A 21 year old female with positive HCG (pregnancy test) presented for radiological (ultrasound) confirmation of cyesis, though no sonic evidence of gravidae was observed (< 5 wks GA); confirmatory ectopic kidney was diagnosed on completion of ultrasound. This report underscores the importance of imaging the RT groin and illiac region before surgical intervention thus preventing iatrogenic injury genesis. Treatment of this condition will depend on the functional capacity of the kidney, while nephrectomy is recommended for 'static' nonfunctional kidneys. Non-complicated cases and anatomic variation can be managed conservatively.
