The corpus callosum and pericallosal
arteries were identified and entry to lateral ventricle was made.
In this report, we present a patient with repeated and recurrent meth abuse who demonstrated rapid growth of a pericallosal
aneurysm over the period of fewer than two weeks.
Post-contrast images demonstrated linear enhancement surrounding pericallosal
arteries consistent with vasculitis.
Dawson fingers (Figure 4) involving pericallosal
areas perpendicular to corpus callosum were seen in 3 cases.
Near the superior frontal gyrus, these arteries anastomose with branches from the pericallosal
artery of the anterior cerebral artery.
Magnetic resonance imaging of the brain revealed periventricular and pericallosal
hyperintense lesions that were typical of MS (Figure 1, 2).
Recently, study has demonstrated a significant increase of cortical IL-1[beta] as early as 1 h after the beginning of reperfusion, the cytokine being mainly expressed in cortical neurons and pericallosal
astroglial cells .
region as well as the quadrigeminal and suprasellar cisterns is the common location for intracranial lipomas.

Brain lipomas are rare congenital lesions usually asymptomatic and with pericallosal
or midline location.
