Pneumoperitoneum caused by tubo-ovarian abscess in an elderly patient.

Perforation of the gastrointestinal tract may present with abdominal pain and imaging demonstrating pneumoperitoneum. These findings usually require exploratory laparotomy for diagnosis and treatment. Tubo-ovarian abscess (TOA) is a complication of pelvic inflammatory disease presenting as an encapsulated inflammatory mass, but it can occasionally involve other pelvic organs.

Advanced extrauterine pregnancy at 33 weeks with a healthy newborn.

Abdominal pregnancy is a very rare form of ectopic pregnancy, associated with high morbidity and mortality for both fetus and mother. It is, and often, seen in poor resource nations, where early diagnosis is often a major challenge due to poor prenatal care and lack of medical resources. An advanced abdominal pregnancy with a good fetal and maternal outcome is therefore a more extraordinary occurrence in the modern developed world.
