Psoas abscess after uncomplicated vaginal delivery: An unusual case

with various sites of haemorrhage such as the lungs, pericardium, gastrointestinal tract, adrenals, muscles, neural tissue, ocular orbits, corpus luteum and anterior chest wall (Sherer et al. 1999). Retroperitoneal haematoma in heparinised patients has also been reported previously (Di Rosa et al. 1997). The symptomatology can mimic radiculopathy and can cause confusion in diagnosis, leading to late recognition of severe complications (Emery and Ochoa 1978). Sherer et al. (1999) reported the first case of a spontaneous retroperitoneal haemorrhage secondary to heparin therapy during pregnancy. They stated that non-specific symptomatology in such patients should always heighten suspicion of a possible delayed or concealed haemorrhage. Although the underlying causes usually cannot be found in every case, minor trauma is generally blamed. In our case, the outcome was fetal demise illustrating one of the most serious results of such a complication in pregnancy. In conclusion, heparin therapy during pregnancy can cause serious maternal and fetal complications. Massive concealed bleeding in the retroperitoneal region must always be suspected in cases of doubtful lower extremity pain resembling radiculopathy.
