Calcification of the choroid plexus visualized by computed tomography
MT Modic, MA Weinstein, AD Rothner, G Erenberg, PM Duchesneau and B Kaufman
Physiologic calcification of the choroid plexus increases in frequency and
extent with age. As demonstrated in this report, it is visualized nine to
15 times more frequently with computed tomography (CT) than with plain
skull radiography. Calcification involving the temporal horns is associated
with neurofibromatosis. Young patients with exuberant calcification in the
region of the glomerula, or with calcification extending into the bodies of
the lateral ventricles should be evaluated for conditions associated with
pathological calcification of the choroid plexus. This also applies to
patients of any age in whom calcification of the choroid plexus in the roof
of the third ventricle or in the region of the foramen of Monro can be
visualized with routine CT center and window levels.
