Section through a benign acoustic neuroma (schwannoma, neurilemoma) showing the classic “zebra” pattern.  The dark areas represent Antoni A areas and the lighter areas in between are Antoni B areas. Patients present with nerve deafness and sensory changes on the face from compression of CN V in the cerebellopontine angle. Recall the relationship of these tumors with neurofibromas. Acoustic neuromas are the third most common tumor in the CNS and derive from Schwann cells.

Sections through the brain of a child who died of congenital CMV showing periventricular calcification (dystrophic calcification) CNS calcification may also occur with congenital toxoplasmosis and congenital Herpes.

India ink preparation of CSF showing Cryptococcus neoformans (most common cause of CNS fungal disease in immunocompromised patients)

Note the narrow-based bud and clear area around the yeast representing the thick capsule

Neuroblastoma, Homer Wright Rosettes are circular groupings of dark tumor cells surrounding pale neurofibrils (small blue cell tumors from neural crest ectoderm). This histologic finding is found in neuroblastoma, medulloblastoma and retinoblastoma.

Characteristics of neuroblastoma include overexpression of the N-myc oncogene, bombesin tumor marker and neurofilament positive histological stains. 

Note: Do not confuse with Perivascular Pseudorosettes/Rosettes found in Ependymomas

Ependymoma exhibiting the histological finding of perivascular pseudorosettes, which are particularly sensitive for diagnosing ependymomas. 

Do not confuse with the Homer Wright Rosettes found in neuroblastoma, medulloblastoma and retinoblastoma.
