Gallbladder Sonogram. Stone, Cyst, Vascular Calcification, Or Angiomyolipoma?
It is very difficult to pin point one amongst the reasons of echogenic focus in the Ultrasonograph of Gall Bladder. You may clear you doubt by going for CT / MRI scan. The reason can be confirmed by that.
Analysing each reason here:
Gall Bladder Stone is very common. If there are no symptoms then no intervention is required.
Small Haemorrhagic Cyst rarely has an echogenic area inside as it is full of liquid. Long-standing Cyst will have some deposition which may be echogenic.
Vascular Calcification is a calcium-filled in vessel.
Tiny Angiomyolipoma is filled with fat and muscles.
Nothing is to be done in any of the above conditions, if there are no symptoms. They may be accidental findings.
But if you anxious about it you may go for Laproscopic Cholecystectomy, that is removal of Gall Bladder by Laproscopy and send the specimen for biopsy.
Waiting to solve your query during follow-up.
