Ectopic pregnancy implanted under the diaphragm: A rare case report

Figure 1 Vaginal ultrasound showed a mixed echogenic mass in the right ovary.

Figure 2 Computed tomography plain scan showed a curved high density mass beneath the subhepatic space.

Figure 3 Magnetic resonance imaging scan showed a curved mixed signal beneath the subhepatic space, mostly low in T1-weighted imaging and high in T2-weighted imaging. Diffusion-weighted imaging showed restricted diffusion. A peripheral enhanced nodule was observed within the mixed curved signal after administration of gadolinium. T1WI: T1-weighted imaging; T2WI: T2-weighted imaging; DWI: Diffusion-weighted imaging.

Figure 4 Abdominal ultrasound showed a mixed echogenic mass in the right lobe of the liver near the apex of the diaphragm. A: The mass was approximately 1.5 cm × 1.1 cm in size; B: The mass showed characteristic features of a gestational sac, with a bud of approximately 0.4 cm in length (indicated by a bright dot in the dark zone).

Figure 5 A mass measuring 5 cm × 3 cm, with dark red surface, was found under the right diaphragm on operation.

Figure 6 Histopathology findings confirmed the diagnosis of ectopic pregnancy. Chorionic villi were present within the mass, with no features of abnormal trophoblastic proliferation (black arrows).
