title: Case report 774. Coincidental parosteal lipoma with osseous excresence and intramuscular lipoma.
abstract: The parosteal lipoma is a rare but recognizable lesion. The combination of (a) a well-defined, radiolucent, soft-tissue mass that on CT is confirmed to be entirely composed of homogenous mature adipose tissue and (b) an osseous excresence and/or saucerization at the attachment of the soft-tissue mass to the subjacent cortex should be diagnostic. We were unable to find any other case report of a parosteal lipoma coexisting with another lipoma in the same individual.
