Is definition of “fetus in fetu” needs revision?: A case report and review of literature

Abstract

Fetus in fetu is a rare clinical entity consisting of malformed fetus inside body of the living partner. It is a mass containing a vertebral axis and often other organs and/or limbs. Unlike other classical cases, this case was not having a vertebral axis but other clinico-pathological findings were suggestive of fetus in fetu. To include such types of cases, the traditional definition by Willis of fetus in fetu needs revision.
