Abstract

Beta Human Chorionic Gonadotrophin (b hCG) assays are sandwich chromatographic immunoassays which give a false negative results at high hCG concentrations and also in the presence of variants of hCG like hyperglycosylated hCG and hCG core fragments. This is imperative in everyday clinical scenario as it delays the diagnosis of pregnancy and its related complications. We have discussed two such cases where in the first case the diagnosis of hydatidiform mole was delayed due hook effect whereas in the second case the diagnosis of GTD was missed because of variant hook effect. Keywords: Hcg – human chorionicganadotropin.

Pregnancy in a caesarean scar is a rare entity where the pregnancy is implanted into a prior caesarean delivery uterine scar and located outside the normal uterine cavity. We report a case of caesarean scar ectopic pregnancy occurring in the scar of a previous caesarean section, diagnosed by ultrasonography and Doppler and the surgical management of such a case following failure of medical therapy. We present history, clinical findings and imaging of our case followed by discussion about, diagnosing and management of such a case and the options available.
