Dynamic computed tomography of the pituitary gland: the "tuft sign"

JF Bonneville, F Cattin, K Moussa-Bacha and C Portha

Diagnosis of an intrasellar pituitary microadenoma by CT may be difficult if the only finding is a small defect in enhancement. The diagnosis can be facilitated by dynamic CT of the pituitary gland in the coronal plane. This method permits visualization of the capillary bed of the pituitary, whose displacement ("tuft sign") could be an indication of the presence of a microadenoma.
