impact of serum ca19-9 level in clinico- pathological and radiologic feature of mature cystic teratoma: a case series

Background objective: ovarian mature cystic teratomas (omcts) are one of the most common benign ovarian tumors. most mcts can be diagnosed by ultrasonography (us). due to heterogeneous composition and a variety of appearance, in some non-diagnostic imaging reports it is suggested that we evaluate some tumor markers (ca125 and ca19-9) to complement imaging modalities. according to previous investigation, a single elevated ca 19-9 is in association with specific radio-pathologic features, such as size, torsion, bronchial glands, fat and teeth components. here we are presenting three different cases of omct with different characteristics.case presentation: case 1: asymptomatic, non-diagnostic us, single- elevated ca19-9, smaller than in 10 cm with bronchial glands and fat component. case 2: symptomatic, non-diagnostic u.s. normal ca19-9, larger than 10 cm with torsion and necrosis. case 3: symptomatic, diagnostic us, single- elevated ca19-9, smaller than 10 cm, full of hair and sebaceous material. computer tomography (ct), in all of our cases was diagnostic based on omct. apologia of pathologic pathway of elevated ca19-9 in both cases 1 and 3 were in agreement with the result of previous investigations. in case 2, despite its large size and torsion, ca 19-9 level was low.conclusion: single- elevated ca 19-9 level in omcts could impact benign characteristics of this kind of tumor.
