Postcontrast axial (a), sagittal (b) and coronal (c) MRI brain and CT brain with stereotactic frame showing the coordinates (d), of a 12-year-old boy with multiple cranial nerve involvement. The images reveal an ill defined lesion in the pons, which demonstrates heterogenous enhancement with contrast. Initial stereotactic biopsy was inconclusive and subsequent STB yielded a diagnosis of anaplastic astrocytoma
