A 42-year-old man diagnosed to be
HIV positive and on highly active antiretroviral
treatment (
HAART), presented with
double vision and gradual drooping of the left
eyelid. He had left 3rd
cranial nerve palsy and partial right lower-motor-
neuron facial palsy. CT of the PNS revealed soft
tissue filling the right
maxillary sinus antruin. Further workup showed the mass to be an NK/
T cell lymphoma.
