A 77 year old female presented with progressively enlarging left lower eyelid lesion. Diffusion restricted imaging (DWI) was hyperintense, suggesting hypercellularity of the lesion. Biopsy was consistent with atypical lymphoid infiltrate.
A. Axial T1+C FS image showing left lower lid uniform contrast enhancement (arrow).
B. Axial DWI revealing hyperintense signal (arrow).
C. ADC map revealing corresponding hypointense signal (arrow), signifying true diffusion restriction.
D. Axial T2 FS at the mid orbit showing expansion of the left lateral rectus, with associated hypointense signal (arrow).
E. DWI showing hyperintense signal (arrow) in the left lateral rectus. Features suggest an additional site of lymphoid tissue infiltrate.
