Pregnancy in a patient with Wegener's granulomatosis: a case report.

Background: Pregnancy in patients with Wegener's granulamotosis (WG) is rare, and differential diagnosis of WG flare and preeclampsia is difficult.

Case: A pregnant 35 year old with WG was referred with diagnosis of severe preeclampsia; caesarean section was performed. Intubation of the patient was difficult due to subglottic stenosis. Because of the clinical symptom, the case was considered preeclampsia, but p-ANCA of the patient was positive. In pregnancies with WG, differential diagnosis of WG flare-ups from preeclampsia should be made from clinical symptoms and laboratory findings. Serum ANCA titers are not useful in the differential diagnosis of WG flare-ups and preeclampsia because it may be positive in preeclampsia.

Conclusion: Differential diagnosis of WG flare-up and preeclampsia should be made by clinical features. In the patients with subglottic stenosis, general anesthesia should not be preferred due to the probability of difficult intubation.
