Abstract

Carbohydrate antigen 19-9 (CA19-9) is a tumour marker elevated in many gastrointestinal malignancies as well as in mucinous tumours of ovary, mature cystic teratomas and various other benign lesions. We present a case of mucinous borderline ovarian tumour with multifocal micro-invasion and torsion and associated with very high levels of serum CA19-9 in a 41-year-old woman. This report highlights that tumour markers and radiological findings may not be accurate in diagnosing the histological sub-type of ovarian tumour.
