Imaging findings are presented for 37-year-old woman with interstitial pregnancy.. A. Initial contrast enhanced axial CT image shows strong enhancing ring-like mass (arrow) that represents gestational sac without hemoperitoneum. Mass abuts uterine fundus in right pelvis.. B. Follow-up CT image obtained after four days shows amorphous hematoma (arrowheads) with massive hemoperitoneum caused by ruptured interstitial pregnancy. Previous strong enhancing ring-like mass in right pelvis is now seen as heterogeneous enhancing mass (arrow) after rupture of interstitial pregnancy.. C. Coronal multiplanar reconstruction CT image shows heterogeneous enhancing mass (arrow) that abuts uterine fundus (arrowheads), suggestive of interstitial pregnancy. Note that there is hypodense line between mass and uterine fundus. CT image demonstrates hematoma around uterus and hemoperitoneum.

A CT image demonstrated a strong enhancing ring-like mass that abutted the uterine fundus in the right pelvis (Fig. 1A). The previous strong enhancing ring-like mass in the right pelvis was now seen as a heterogeneous enhancing mass on a follow-up CT image (Fig. 1B). The heterogeneous mass abutted the uterine fundus in the right pelvis and a linear hypodense line was noted between the mass and the uterus (Fig. 1C).
