About 1 in 5 early pregnancy presentation will not be localized on initial ultrasound scan. These pregnancy of unknown location (PUL) are frustrating for both the woman and the clinician, particularly if serial ultrasound scans fail to visualize the pregnancy and serial serum �²hCG fail to demonstrate spontaneous resolution.Concerns of ectopic pregnancy may lead the clinician to perform diagnostic interventions such as laparoscopy or dilatation & curettage of the uterus. These carry operative risks and may inadvertently terminate an early pregnancy. Conversely, failure to investigate these cases may miss trophoblastic neoplasia. There is no consensus as to the duration of follow-up in a PUL before it is considered a �persistent PUL� where intervention may be warranted. The author will discuss the basis of classification of persistent PUL and management alorigthm.
