Ultrasonographic features of intraocular lymphoma / 中华超声影像学杂志

ABSTRACT

Objective To describe the ultrasonographic features of intraocular lymphoma . Methods It was a retrospective analysis of 19 patients ( 26 eyes ) with intraocular lymphoma at the department of ophthalmology ,Beijing Tongren Hospital from January 2015 to December 2017 . T he diagnosis was established by tissue biopsy in 4 patients with diagnostic vitrectomy and 8 with enucleation ,and other 7 cases were clinically diagnosed followed by pathological examination of central nervous system lymphoma . T he ultrasonographic features of all patients were analyzed . Results Of the 19 patients ( 26 eyes ) with intraocular lymphoma ,12 cases ( 19 eyes) of vitreoretinal lymphoma accounted for 63 .2% ,of which 7 cases were bilateral eyes ,and 7 cases ( 7 eyes ) of uveal lymphoma accounted for 36 .8% ,all of w hich were monocular . Ultrasonography of vitreoretinal lymphoma included vitreous opacity , posterior vitreous detachment ,partial retinal detachment ,irregular hypoechoic lesions under the retina ,and CDFI detected blood flow signals in the lesion . T here were two different types of ultrasound findings in uveal lymphoma . Five cases ( 5 eyes ) showed diffuse thickening of the uveal membrane with low echo , and irregular hypoechoic mass around the optic nerve and the ball wall ,in w hich CDFI detected abundant blood flow signals . Ultrasound biological microscope examination showed that the iris‐ciliary body thickened and the internal echo decreased . T his ultrasound finding accounted for 71 .4% of uveal lymphoma . T wo cases ( 2 eyes) showed a solitary ciliary‐choroid choroidal hypoechoic mass ,combined with retinal detachment and blood flow signals with CDFI ,accounting for 28 .6% of uveal lymphoma . Conclusions T he ultrasonography of intraocular lymphoma is various . T he ultrasound findings of vitreoretinal lymphoma are not specific , w hile the diffuse thickened uvea and retrobulbar hypoechoic lesions encircled optic nerve and eye wall suggest the possibility of uveal lymphoma .
