A newborn with massive intra-abdominal haemorrhage.

We describe an unusual case of an intra-abdominal teratoma with massive bleeding presenting as sudden cardiovascular collapse immediately after birth. The infant required massive volume and blood product transfusion, alongside emergent tumour resection, in order to obtain haemostasis and haemodynamic stabilisation. Haemorrhage of a sacrococcygeal teratoma is a known entity, but we are not aware of a previous report of massive intra-abdominal haemorrhage due to a teratoma, immediately after birth. This case emphasises the need to consider intra-abdominal pathology, including a teratoma, in the differential diagnosis of any newborn with early hypovolaemic shock and abdominal distention. 2015 BMJ Publishing Group Ltd.
