Answer is A. Diagnosis is Mucinous cystadenoma Most common cystic neoplasm of pancreas Up to 95% are seen in women Usually arise from the tail of pancreas Cystic cavities usually filled with thick mucinous material Columnar mucin-producing epithelium that lines the cysts is associated with a dense stroma similar to ovarian stroma Precursor to invasive carcinoma, up to 1/3rd are associated with invasive adenocarcinoma CECT showing peripheral egg shell calcification Surgical resection is curative for noninvasive mucinous cystic neoplasms (distal pancreatectomy).
