    Notes: Summary In the last few years complete or partial regression of prolactinomas has been demonstrated in nonpregnant women treated by bromocriptine. Thus bromocriptine therapy appears as an attractive alternative to surgery for management of infertility related to hyperprolactinemia. However, numerous reports emphasized the possibility of an excessive growth of the pituitary adenoma with visual field defects during the last 3 months of pregnancy. To avoid these complications, the authors followed with serial CT scans the growth of microprolactinoma at the 5th or 6th month of pregnancy. Among six pregnant women, one patient presented a marked upward extension of the adenoma. Bromocriptine was then reintroduced and the effectiveness in reducing tumor growth was proved by CT scan at the 7th month. Regarding low risk of using intravenous iodinated contrast medium in pregnant women and of fetal radiation damage, the authors emphasize the value of CT in the follow-up of bromocriptine-induced pregnancies.

    Notes: Abstract We describe the MRA and MR angiography (MRA) features of persistent trigeminal artery (PTA) found incidentally in eight patients, with special attention to its origin, site and course. The different patterns of posterior communicating arteries were also noted. The PTA were shown on sagittal, coronal and axial MRI and on MRA. In four cases, the PTA arose from the lateral aspect of the intracavernous internal carotid artery, ran caudally, passing round the bottom of the dorsum sellae to join the basilar artery. In the other four cases, it arose from the medial aspect, ran caudally through the sella turcica and pierced the dorsum sellae to join the basilar artery. The posterior communicating arteries were present unilaterally in five cases and bilaterally in one, and absent bilaterally in two. Identification of a PTA with a trans-sellar course is crucial if a trans-sphenoidal surgery is planned.
