Adult Ocular Toxocariasis Mimicking Ciliary Body Malignancy

Abstract

Purpose. To discuss an unusual presentation of ocular toxocariasis. Methods. Case report. Results. A 40-year-old woman presented with decreased vision in the left eye with a long history of recurrent red eye from uveitis. Eosinophilia and positive ELISA titers for Toxocara canis favored the diagnosis of ocular toxocariasis. Over 3 months, an anterior scleral mass had a rapid growth raising the possibility of medulloepithelioma, which rarely can mimic uveitic syndromes. Surgical plan changed from local excision to enucleation. Histopathology demonstrated a large homogeneous mass of chronic inflammatory cells with inflammation of the overlying thinned out sclera, medial rectus insertion, and limbal cornea. The triad of peripheral granuloma, eosinophilia, and positive blood serology established the diagnosis of ocular toxocariasis. Conclusions. Ocular toxocariasis can mimic ocular malignancy such as medulloepithelioma in adults and rarely presents as an anterior scleral mass.

Choroby odzwierzęce w okulistyce. Część 2. Zespół larwy wędrującej ocznej

“…Zdarzają się trakcyjne lub przedarciowe odwarstwienia siatkówki i wynaczynienia krwi. Larwa może zawędrować do każdej struktury oka i spowodować tam niecharakterystyczną reakcję zapalną [22,23]. Nie potwierdzono opinii, że toksokaroza obecna poza okiem też może być przyczyną uogólnionego zapalenia błony naczyniowej.…”

Multimodality Image Analysis in a Cohort of Patients with Atypical Juvenile Ocular Toxocariasis

“…Although typical OT can be diagnosed by signs of retinal granulomatosis or toxocariasis endophthalmitis [ 2 ], OT patients with atypical manifestations are likely to be misdiagnosed. These atypical OTs include involvement of the ciliary-body [ 3 ] or lens [ 4 ] invasion, intraocular tumors, and optic-nerve swelling [ 5 ]. Recently, improved multimodal ophthalmic-imaging technologies have unveiled the details of retinal lesions in OT.…”
