congenital intraspinal cysts Flashcards
spinal arachnoid cyst genetic sybdroms
hereditart distichiasis, neurocutanous melanosis, and noonan sydrome - also with spinal dysraphisms- splitcord
arachnoid cyst location
usually dorsal to spinal cord
type of cells found on arachnoid cyst pathology
meningothelial cells
location of neuroenteric cysts
intradural extramedullar space in the ventral cervical or throracic spine
associated veterebral column anomolies
sacral agensis, block vertebraw, hemivertebra, klippel-feil, butter fly vertebrae
embylogic origins
spliting of notocord with connection between endoder and ectoder, incomplete excalation of the notorcord, and ectopic spinal rests of endoderm
pathology of neuroenteric cysts
thin walled epithelial layer with goblet cells, ciliated cells, and squamous epithelium
dermoid and epidermoid cyst origin
rest of ectoderm during 3 to 5week of gestation with neural tube closes
