1 NeuroPathology Page 8 Brain Tumors Pathological finding Pseudorosette Rosenthal fibers Rosettes Wet Keratin Psammoma bodies Fried egg Tumor Ependymoma, SEGA Pilocytic astrocytoma Medulloblastoma Craniopharyngioma Meningioma Oligodendroglioma Medulloblastoma Kids, midline, Cerebellum, diffuse contrast enhancement Can seed in CSF (drop mets) but rarely involve meninges On MRS, there is a choline and taurine peak Stains positive for Synaptophysin Rosettes formation Pilocytic astrocytoma: Kids, cystic with an enhancing mural nodule. Can occur in optic tract in patients with NF1 Associated with BRAF gene mutation Pathology: Cells with long processes Rosenthal fibers (intense red deposits formed of hyaline) Hair like processes arranged in bundles, resemble mats of hair Rosenthal fiber Smear of pilocytic cells
2 NeuroPathology Page 9 SEGA: In patients with TS (TSC1 in ch 9q34 and TSC2 in ch 16) Pathology: large polygonal cells with abundant eosinophilic cytoplasm, perivascular pseudorosettes GFAP H&E Oligodendroglioma: Adults, lobar, associated with IDH mutation Anaplastic (Grade III) associated with allelic loss at ch 1p and 19q Pathology shows rounded nuclei, prominent cytoplasm with clear halo (Fried egg) GFAB stain H&E Colloid cyst: Usually arise in the 3rd ventricle close to the foramen of Monroe MRI: isointense on T1, hyperintnse in T2 Pathology shows simple cuboidal or columnar epithelium, full of proteinaceous material
3 NeuroPathology P a g e 10 Ependymoma: Usually arise in 4th ventricle (children) or spinal cord (adults) Can seed through CSF Pathology: perivascular pseudorosettes (Ependymal cell processes directed towards vessel wall with formation of perivascular anuclear zones of GFAP+ fibrillary processes) Subependymoma: Arise in 4th ventricle in adults, doesn t enhance Clusters of cells embedded in dense glial fibrillary background, there may be pseudorosette Hemangioblastoma: Cystic cerebellar tumor in adults with nodule of blood vessels, can involve the spine in VHL Pathology: vacuolated cells and vascular structures (packed thin walled vessels and large neoplastic cells with pink to clear cytoplasm with fine vacuoles containing PAS+ lipid)
4 NeuroPathology P a g e 11 Meningioma: Pathology shows: Psammoma bodies (laminated calcific concretions) and whorls formation (cells arranged in whorls) Meningothelial whorls Psammoma bodies in psammomatous meningioma Choroid plexus papilloma: Arise in lateral ventricle in children, homogenous enhancement Pathology: papillary or villous architecture (single layer of epithelial cells overlying a fibrovascular core) Pituitary adenoma: Rounded or polygonal cells, rounded nuclei, cytoplasm either chromophobic, acidophilic or basophilic according to hormone production Chromophobic GH Producing (acidophilic)
5 NeuroPathology P a g e 12 Craniopharyngioma: Suprasellar tumor in children, usually calcified Pathology: Keratinocytes in spheres called wet Keratin. Rathke s cleft cyst: Suprasellar cystic tumor, isointense, nonenhancing Pathology: cyst lined with ciliated columnar epithelium with goblet cells. Pictures from Radiopedia Picture from Medscape website
6 NeuroPathology P a g e 13 Hypothalamic hamartoma In children, causes gelastic seizures and precocious puberty MRI: nonenhancing, isointense Pathology: hypocellular mass of mature glia and neurons Germinoma: Suprasellar or pineal (most common pineal tumor) Pathology: small reactive lymphocytes and large neoplastic germ cells.
7 NeuroPathology P a g e 14 Pineocytoma: In Adults, low grade tumor, contrast enhancing Pathology: characterized by large anuclear areas called pineocytomous rosettes DNET: Children or young adults MRI: Cortical, soap bubble appearance in MRI, no enhancement Pictures from Radiopedia Nonenhancing
8 NeuroPathology P a g e 15 CNS lymphoma: MRI: homogenous enhancement, vasogenic edema in T2, diffusion restriction in DWI Usually arise at the edge of the ventricle FLAIR T1+C Epidermoid cyst: Caused by entrapment of ectodermal tissue in neural tube during development MRI: CSF signal in T1/T2, heterogenous in FLAIR, restricted diffusion (unlike arachnoid) Pathology: cyst lined by squamous epithelium, filled with keratin and cholesterol. T1 + contrast T2 DWI
