Acute massive haemothorax is a life-threatening situation,
which is often associated with a preceding trauma. However,
spontaneous haemothorax is a rare occurrence, especially in
pregnancy. Spontaneous haemothorax in the immediate
post-partum period secondary to a ruptured intercostal AVM
is extremely rare more so in the background of an
undiagnosed neurofibromatosis. This is a report of a young
lady presenting with pleuritis and breathlessness after the
delivery of her 1st child. Her management is discussed.
