Primary Brain Tumors

Front 1

PSEUDOPALISADING, pleomorphic tumor cells-corder central areas of necrosis and hemorrhage

Back 1

glioblastoma multiforme (grade IV astrocytoma)

Front 2

slow-growing, well-circumscribed; spindle cells concentrically arranged in whorled patterns PSAMMOMA BODIES (laminated calcification)

Back 2

meningioma

Front 3

schwann cell origin; bilateral tumor, associated with NF2; often localized to CNVIII; S100+; PNS

Back 3

Schwannoma

Front 4

slow-growing; "chicken wire capillary pattern", "FRIED EGG" cells--round nuclei with clear cytoplasm

Back 4

oligodendroglioma

Front 5

rathke's pouch; prolactin-secreting; bitemporal hemianopia (due to pressur eon optic chiasm) & hyper or hypopituitarinism sequelae

Back 5

Pituitary adenoma

Front 6

supra-tentorial, well-circumscribed, pediatric brain tumor; rosenthal fibers=EOSINOPHILIC, CORKSCREW fibers=hair-like glial processes associated with microcysts

Back 6

pilocytic
(low-grade astrocytoma)

Front 7

highly malignant tumor CEREBELLUM; can compress 4th ventricle --> hydrocephalus; ROSETTES

Back 7

Medulloblastoma

Front 8

child's tumor; PERIVASCULAR PSEUDOROSETTES, 4th ventricle--> hydrocephalus

Back 8

Ependymoma

Front 9

FOAMY CELLS, cerebellar, children, associated with von Hippel-Lindau syndrome when found with retinal angiomas; produce ERYTHROPOIETIN--> 2ary polycythemia

Back 9

Hemangioblastoma

Front 10

BENIGN childhood tumor, may cause bitemporal hemianopia, most common childhood supratentorial hemianopia ; derived from remnants of Rathke's pouch, calcified (tooth enamel-like)

Back 10

Craniopharyngioma
