nerve-sheath-tumors
A 45-year-old woman presents with a 3cm mass in her forearm. MRI shows a well-circumscribed, fusiform mass arising from the median nerve with a split-fat sign and target sign on T2-weighted imaging. Percussion over the mass produces paresthesias in the median nerve distribution. What is the most likely diagnosis and key surgical consideration?
Mark each as TRUE or FALSE
Schwannoma; can typically be enucleated without sacrificing the parent nerve
Neurofibroma; requires resection of the involved nerve segment
MPNST; requires wide resection with negative margins
Ganglion cyst; simple excision is curative
Lipoma; marginal excision is adequate
