Basanti, a 28yrs aged female with a history of 6 weeks of amenorrhea presents with pain in abdomen; USG shows fluid in pouch of douglas. Aspiration yields dark colour blood that fails to clot. Most probable diagnosis is:
Ruptured ovarian cyst
Ruptured ectopic pregnancy
Red degeneration of fibroid
Pelvic abscess
Aspiration of blood clots or dark coloured blood that fails to clot, signifies collection of intraperitonial blood. Pain in abdomen and blood in pouch of doglas in a woman of child bearing age (28yrs) with history of 6 weeks amenorrhea suggests a diagnosis of ruptured ectopic pregnancy.
