surgical managment of complex spinal cord lipomas Flashcards
1
Q
what is dorsal lipoma
A
lipoma–cord interface is entirely on the dorsal surface of
the lumbar spinal cord, always sparing the distal conus
2
Q
what is chaotic lipoma
A
begins dorsally in an orderly fashion, like a dorsal or transitional
lipoma, but its caudal portion is ventral to the neural placode
and does engulf neural tissue and nerve roots
3
Q
WHAT timing in embryology causes a dorsal spinal lipoma
A
non disjunction during primary neurulations
4
Q
cause of a transitional lipoma
A
likely primary adn secondary neuroalation given the non disjunction in primary
5
Q
whats associated with caudal lipoma
A
caudal agensis then giving idea related to secondary neuralation- specifically condensation of the medullary cord
