“…In humans, diagnosis of ectopic pregnancy includes analysis of serum β-human chorionic gonadotropin and progesterone levels, ultrasonography, diagnostic laparoscopy, and endometrial biopsy, among others (Corpa 2006;Sivalingam et al 2011). Although ultrasonography is the most preferred method in the diagnosis of ectopic pregnancy, CT or magnetic resonance imaging (MRI) can also provide sufficient evidence to make a diagnosis if clinical prediction has not been confirmed (Anderson et al 2009;Kao et al 2014). CT and MRI methods allow more accurate and rapid diagnosis by dint of sectional imaging (Febronio et al 2012;Kao et al 2014).…”

Indeed, CT and MRI play increasingly important roles in the diagnosis of ectopic pregnancies (Febronio et al 2012).…”

An intact female Maltese dog, rescued two months previously, and weighing 2.7 kg, was presented for ovariohysterectomy. There were no typical clinical signs and evidences of parturitions. A firm abdominal mass was palpated, which was identified as a round-shaped radiopaque mass in survey radiography. The mass was tentatively diagnosed as an extrauterine foetus with mummification on computed tomography (CT). Surgical removal of the mass and ovariohysterectomy were performed. Histopathological examination yielded a final diagnosis of abdominal ectopic pregnancy.

“…This objective can be very challenging, however, because the clinical symptoms, physical examination, and laboratory tests of omental pregnancy are nonspecific, and approximately half of abdominal cases can be sonographically occult [5]. In such situations, CT might be inadvertently used for evaluation and diagnosis, especially for patients in an unstable condition [6] (as in our case). With increasing use of CT scans in emergency departments, it is increasingly important for radiologists to know the CT features of ectopic pregnancy.…”

CT findings of omental pregnancy: a case report

Omental pregnancy is an extremely rare and dangerous form of ectopic pregnancy which can be very difficult to diagnose radiologically. We report the case of an 18-year-old girl with secondary omental pregnancy who was assessed by use of contrast-enhanced computed tomography (CT). For the first time, we report the contrast-enhanced CT features of omental pregnancy. Inhomogeneous mild enhancement was observed, which is different from other kinds of ectopic pregnancy, for which enhancement is often substantial. Possible reasons for the discrepancy are discussed, as also is differential diagnosis of omental pregnancy.

“…The present study revealed a mass in the right hepatic lobe for which the peripheral portion had increased glucose metabolism (SUVmax, 5.7) while the central portion did not exhibit increased glucose metabolism. Familiarity with the typical and atypical US, CT, MRI and PET-CT appearances of various forms of ectopic pregnancy facilitates the prompt and accurate diagnosis and treatment of this condition (43). (44).…”

Abstract. The present report describes the case of a 31-year-old woman diagnosed with an ectopic pregnancy in the liver. The patient presented with amenorrhea for 40 days and abdominal distention for 27 days. A liver mass had been detected 6 days prior to presentation. Using ultrasound (US), a hyperechoic mass with a fluid sonolucent area was detected in the right hepatic lobe. Examination by computed tomography (CT) revealed the presence of a mass in the right hepatic lobe with a slightly low-density peripheral region and an oval central portion of lower density in the plain scan; the enhanced scan revealed a significantly enhanced peripheral region and a non-enhanced central portion.18 F-fluodeoxyglucose (FDG) positron emission tomography (PET)-CT showed a mass in the right hepatic lobe with an increased intake of FDG in the peripheral region (maximum standard uptake value, 5.7) and a non-increased intake of FDG in the central portion. The patient was then subjected to hysteroscopy and laparoscopy. Histopathologically, the mass was an ectopic pregnancy. The patient recovered following the surgery. In conclusion, a timely diagnosis of ectopic pregnancy was made for a 31-year-old women with an ectopic pregnancy in the liver on the basis of US, CT and PET-CT imaging results, which enabled surgery to be undertaken prior to any serious consequences. These observations may be helpful for the diagnosis of similar cases in the future.
