title: Literature statistics do not support a growth stimulating role for female sex steroid hormones in haemangiomas and meningiomas.
abstract: A literature review of pregnancy-related vertebral haemangiomas, pregnancy-related haemangiomas outside the nervous system and its coverings, and pregnancy-related meningiomas was performed. All three conditions tended to occur during the first pregnancy, the second or third trimester, to ameliorate postpartum, and to recur during a subsequent pregnancy. These results suggested a hormonal influence on the clinical expression of haemangiomas and meningiomas. To test whether a hormonal factor is also operative in the (not pregnancy related) symptomatic and asymptomatic counterparts of these conditions we also reviewed the literature concerning the symptomatic and asymptomatic haemangiomas and meningiomas for the following: frequency, sex and age distribution. No arguments were found to suggest that steroid hormones are strong factors in the development of asymptomatic and symptomatic lesions. The pregnancy-related counterparts have to be considered as subsets with their own behaviour.
