Thanks Teresa for information. Cytological findings show that it has a cylindrical epithelium. This would support the fact that it is not a pseudocyst, because a pseudocyst has a fibrous capsule. CEA 103, Amylase 169. Conclusion: cystic change. I asked the doctors, but they don't have concrete answers. It seems to me that the parameters do not fit into any known in the literature and that is why they avoid specifying the type.
