[|Human|] I had a recent CT scan without contrast a few weeks ago of abdomen due to extreme pain- there was a simple cyst in liver detected measuring 2.8 x 2.8 x 3.0cm. I had a follow up ultrasound that showed hepatic cystic lesion within right lobe. There is thick septation within the cyst. There is cyst wall irregularity which may reflect additional septations which are not visualized in their entirety. Vascular flow is noted adjacent to the cyst. The radiologist is recommending tat I consider tissue sample due to complex character.
[|AI|]  Hello, Thanks for the query to Chat Doctor. Forum. As in C T SCAN diagnosis, confirmed, so only option is type of cyst and its cause. This is cyst with many septa. Most probably this type of cyst is known as Hydrated cyst and this is the most common cause of cyst in the liver. 2nd reason may be traumatic cyst, but this type of cyst is usually large and without septum. Hydrated cyst usually due to a parasite either from pet dog or unripe salad. As you mentioned only cyst so very difficult to say something about the cause of cyst. Anyhow only liver biopsy will find out the exact cause, so consult a surgeon and get it done. Good luck.
