Case Discussion
Well-defined margins with vascularity were two basic findings favoring solid lesion of non-specific etiology. However, these two basic findings were ignored ( definitely by me ) and a suspicious finding of central necrosis was given more importance.
MR done a wk later, showed solid tumor ( not uploaded, no copy right ).
Surgical excision was done - operative finding of a solid lesion.
Histopathology - no necrosis. Solid lesion reported to be fibromatosis.
