Ovarian torsion: incremental role of contrast-enhanced ultrasound

Abstract

We highlight the role of contrast-enhanced ultrasound (CEUS) as a supplementary modality to ultrasound (USG) examination in ovarian torsion in this case report. The reported patient had clinical history suspicious of ovarian torsion; however, USG and Doppler flow study findings were equivocal. CEUS was performed to solve the diagnostic dilemma and to know the status of ovarian parenchymal viability which revealed non-enhancement of the ovarian cyst wall and pedicle throughout the USG examination thus establishing the diagnosis of non-viable or infarcted ovarian parenchyma. The per operative and histopathology findings were consistent with our CEUS findings. CEUS is an emerging promising modality which provides information regarding parenchymal perfusion, resulting in a reliable diagnosis of ovarian torsion along with information on ovarian parenchymal viability. This ability makes CEUS equivalent to contrast-enhanced CT or MRI.
