Congenital Anomaly of Gall Bladder Assessed Through Magnetic Resonance Cholangiography in Relation to Its Clinical Relevance
Objective: The overall incidence of Phrygian cap is about 04%. It is an anomaly of gall bladder found congenitally. It can be a misguided pathological diagnosis often seen mimicking a liver mass on imaging of the hepatobiliary tree. Although Phrygian cap is a congenital anomaly, it does not show any pathological significance, In light of this condition, the purpose of this research was to find out the congenital anomalies of the gallbladder through magnetic resonance cholangiopancreatography (MRCP) along with its clinical significance.
Methods: A total of 377 patients were selected with a number of 192 females and 185 males, with ages ranging from 16-90 years, with a mean age of 48 years, who had undergone MRCP for diagnosed stone in gallbladder or bile duct on a clinical basis, carcinoma of pancreas and inflammatory changes of pancreatic and/or bile ducts. The patient's imaging was done using a 1.5-T superconductive magnet which was four-channel phase-arrayed body coil and breath-holding technique was utilized, using multi-sliced T2-weighting half-Fourier acquisition single-shot turbo spin-echo (HASTE), MIP reconstruction, and also single-shot T2-weighted turbo-spin-echo sequence rapid acquisition with relaxation enhancement (RARE) having a varying thickness of slices.
Results: The MRCP imaging results demonstrated extra hepatic biliary tract anomalies in 94 out of the 377 patients which represented a frequency of 24.93%. However, a Phrygian cap was found to be present in 6 patients with a frequency of 1.6% with 4 females and 2 males.
Conclusion: From the results that we achieved, it was made quite apparent that congenital anomalies can be classified as a complex spectrum of variations that have a propensity to occur on a regular basis, emphasizing their value for attention in clinical as well as surgical settings along with the need to be readily identifiable with MRCP.
