Interstitial Pregnancy Managed with Single-dose Systemic Methotrexate: A Case Report.

Interstitial pregnancy is a rare type of ectopic pregnancy with a high risk of massive hemorrhage on rupture as compared to ectopic on other sites. The mortality rate for the ruptured interstitial pregnancy is high. Therefore, early diagnosis of such pregnancy before the rupture occurs facilitates appropriate management and avoids life-threatening complications. With the advancement in diagnostic imaging modalities, early diagnosis and more conservative management for interstitial pregnancy have become possible. Here, we report a case of primigravida diagnosed with interstitial pregnancy with ultrasonography and successfully managed with a single dose of methotrexate.
