Atypical iliac unicameral bone cyst – An incidental finding in MRI.

is no expansion of the bone with unicameral bone cysts but in our present case there was expansion making it atypical presentation. We present a 22-year male who underwent MRI for Lumbosacral spine for his vague low backache symptoms. There was incidental finding of bony lesion in left iliac bone which turned out to be simple bone cyst. The study of Lumbosacral spine was unremarkable.
