Adnexal masses are often diagnosed in the pregnant patients. Ultrasonography is the first line modality for the determination of adnexal mass nature followed by contrast enhanced MRI assessment. However, these methods are not reliable methods for the detection of malignancy of ovarian masses. In vivo proton magnetic resonance spectroscopy is able to distinguish malignant and benign ovarian tumors.
Patients and Methods:
Sixteen patients with the adnexal masses diagnosed primarily by US were evaluated by in vivo 1H MRS for detection of lipid, lactate a choline peak.
Significant correlation between MRS and with histopathology findings was observed. The correlation between US and histopathology findings was not significant. 1H MRS was properly able to detect malignancy in the 80% of the above patients.
We concluded that 1H-MRS is a reliable method for preoperative characterization of adnexal lesions.
