Giant asymptomatic borderline ovarian tumor in a patient suffering from choledocholithiasis and cholangitis

Borderline tumors account for about 15% of all ovarian epithelial tumors and are usually diagnosed only when they reach a significant size causing abdominal pain or distension. Clinical, sonographic and Doppler examinations, as well as tumor marker levels cannot detect this type of ovarian tumor with certainty. The definitive diagnosis can only be established by a histopathological examination. We present a case of a 58-year-old patient operated on at our clinic for asymptomatic borderline ovarian tumor. Prior to admission, the patient underwent a medical check-up at the surgery department, where she was diagnosed with choledocholithiasis, and, consequently, the need for urgent surgical treatment for calculosis was excluded. In the presented case the ovarian tumor was revealed owing to the occurrence of choledocholithiasis and cholangitis. The choledocholithiasis and cholangitis, which contributed to the accurate diagnosis of the tumor, were at the same time some of the possible reasons for misleading diagnosis and therapy complications in our patient's case.
