Background Heterotopic pregnancy describes the occurrence of two pregnancies in different implantation sites simultaneously, which is rare, yet it is a challenge to diagnose such a problem due to complex clinical and laboratory findings. In the current study, we present a case of first trimester heterotopic pregnancy diagnosed by ultrasound (US) and magnetic resonance imaging (MRI) and was managed successfully. Case presentation A 22-year-old primigravida lady with spontaneous pregnancy was presented by increasing lower abdominal pain for 5 days with brownish vaginal discharge, nausea, and vomiting episodes. Trans-abdominal and endovaginal ultrasound was performed and revealed a viable intrauterine pregnancy of 8 weeks and 1 day, associated with a heterogeneous complex right adnexal mass. MR imaging revealed a right adnexal mass intimately anterior to the normal right ovary. Laparascopy was done; it revealed a distended right fallopian tube with pregnancy while the right ovary was not seen (impeded in the pouch of Douglas), and right salpingectomy was done. The specimen was sent for histopathology. The patient tolerated the procedure well and was then taken to the recovery room in stable condition. The histopathological report confirmed the diagnosis of ectopic pregnancy. Conclusion However, heterotopic is a rare condition, any pregnant woman presenting with alarming abdominal pain and adnexal abnormality; heterotopic pregnancy should be among the differential diagnosis possibilities. The patient should be thoroughly investigated using ultrasound and MRI if needed, to exclude this rare diagnosis and allow on-time proper management.

Background: The aim of current work is to review the CT findings of COVID-19 in a pictorial study to help the radiologists to be familiar to imaging findings of COVID-19. Main body: Coronavirus disease 2019 (COVID-19) is a pandemic highly infectious disease which is first reported in December 2019 in Wuhan, China, and then had its outbreak leads to a global public health emergency. Real-time reverse transcription polymerase chain reaction (RT-PCR) of viral nucleic acid is considered as the reference standard for COVID-19 diagnosis; however, recent studies showed the importance of CT chest in the diagnosis of COVID-19 with high sensitivity. The CT hallmarks of COVID-19 were bilateral peripheral ground-glass opacities, consolidation with the advance of the disease more consolidation is there with linear opacities and crazy-paving pattern as well as halo and reverse halo sign. Conclusion: Early identification of COVID-19 cases is vital. The radiologist should be familiar with the possible findings. Further future studies with pathological correlation will help for more understanding of the imaging findings and its value in assessing of prognosis.
