Synopsis

Intra-tumoral hemorrhage is one of the suggestive pathological findings of malignancy. Surgically proven 16 benign and 64 malignant solid or complex ovarian tumors were retrospectively evaluated. High intensity hemorrhagic foci on T1WI were detected in 16 of 64 malignant lesions (25%), whereas signal voids due to hemorrhage on susceptibility-weighted sequence (SWS) were detected in 41 of 64 lesions (64%). Neither high intensity foci on T1WI nor signal voids on SWS was detected in all 16 benign tumors. We conclude that the demonstration of intra-tumoral hemorrhage in patients with ovarian tumors by SWS may provide valuable diagnostic findings.
