Figure 1.
Figure 1. Axial non contrast CT images reveal a densely calcified soft tissue density lesion in the suprasellar region with associated dilatation of third and lateral ventricles.
Figure 2.
Figure 2. Axial T1 weighted MRI images reveal a heterogeneously solid hypointense mass with a cystic component in the sellar/suprasellar region.
Figure 3.
Figure 3. Axial and Sagittal T2 weighted MRI images reveal a heterogeneously solid hyperintense mass with cystic component in the sellar/suprasellar region with associated dilatation of the third and lateral ventricles.
Figure 4.
Figure 4. Post Contrast Axial and Sagittal T1 weighted images reveal intense homogeneous enhancement of the lesion with a non enhancing cyst.

Histological Slide (haematoxylin-eosin, magnification 100 ×) confirming the diagnosis of pilocytic astrocytoma: biphasic pattern showing a combination of loose glial tissue and compact piloid tissue with elongated bipolar cells showing fibrillary hair-like processes, in addition to Rosenthal fibres.
