PP-01 Phrygian cap of gallbladder a case report.

Objective: The gallbladder is an organ that resembles a pear in shape and serves to store bile. Numerous anomalies and variations have been described regarding the location, shape, number and size of the gallbladder. Starting from the 4th week of pregnancy, the liver, gallbladder and bile ducts emerge as ventral buds from the most caudal part of the foregut.[1] In the embryological period, the folding of the fundus of the gallbladder causes the appearance of an image called the Phrygian cap on ultrasound. Phrygian cap is the most common congenital anomaly of the gallbladder and can be confused with a liver mass or gallbladder duplication ultrasonographically. The frequency of the Phrygian cap has been reported as 1-6%.[2-4] The Phrygian cap is not pathologically significant, but it is important to distinguish it from other possible diagnoses ultrasonographically in the antenatal period.[5] We aimed to share our case diagnosed with ultrasonography in the antenatal period, accompanied by bilateral pelviectasis, and the management of the case. Methods: Computer-based and ultrasonography records of the case with Phrygian cap and pelviectasis, who applied to the Perinatology outpatient clinic of Prof. Dr. Cemil Taşçıoğlu City Hospital at the 20th week of pregnancy, were scanned retrospectively from the hospital system and the history of the ultrasonography device. Fetal ultrasonography examination and abdominal ultrasonography during the neonatal period were performed using Mindray Resona 7 device and its 1.2-6 diagnostic procedures may be offered to parents after satisfactory genetic counselling. Some of these subtle signs may come out as rare karyotype abnormalities of varying severity and significance. [ABSTRACT FROM AUTHOR]
