Background: A pregnancy with Gorham disease (massive osteolysis syndro
me) is described. To our knowledge, this is the first reported case of
a pregnancy associated with this disease. Case: A 25-year-old woman w
as seen for pre-conception counseling with the diagnosis of Gorham dis
ease. Before pregnancy, magnetic resonance imaging confirmed a stable
disease process. The woman and fetus were followed during pregnancy wi
th ultrasound and consultations. Severe pre-eclampsia developed at del
ivery, with a significant thrombocytopenia. We delivered the infant by
low forceps, with a good outcome. Subsequently, the mother and child
were doing well at 18 months postpartum. Conclusion: We briefly review
this rare bone disease as it relates to pregnancy and provide informa
tion for pre-conception counseling.
