Figure 1: (a) Non-contrast computed tomography axial section showing isodense lesion in the third ventricle with dilated lateral ventricles, (b) magnetic resonance imaging (MRI) T1 weighted axial section showing isointense lesion in the third ventricle, (c) MRI T2 weighted axial section showing hyperintense central core with inner isointense and peripheral hypointense rim. Edema is seen in bilateral thalamus, posterior limb of bilateral internal capsule. Small air pocket in right frontal horn of lateral ventricle due to shunt surgery, (d) MRI T2 weighted sagittal section showing intraventricular lesion with mass effect on superior convexity of midbrain with elevation of internal cerebral veins, (e) T1 magnetization transfer images coronal section showing a lesion in the third ventricle with hyperintense rim suggestive of caseating tuberculoma
