Phaeochromocytoma in pregnancy. Five cases and a review of the literature.
We report five patients with phaeochromocytoma associated with pregnancy and review the 42 other cases reported in the literature from 1980 to 1987. The overall maternal mortality was 17% and the fetal loss 26%; antenatal diagnosis of phaeochromocytoma reduced the maternal mortality to zero and the fetal loss to 15%, but was made in only 53% of the patients. Although phaeochromocytoma is rare, a high index of clinical suspicion must be maintained and all those at risk investigated if earlier diagnosis and improved outcome are to be achieved. Once the diagnosis is confirmed, alpha-blockade is essential and beta-blockade may be required. CT scan or magnetic resonance imaging may be used to localize the tumour during the antenatal period. In the first and second trimesters, tumour resection has a good fetal outcome; in later pregnancy, delivery by elective caesarean section followed by tumour resection is recommended.
