Letter to the Editor

Sir, the recent publication on orbital cysticercosis is very interesting.¹ “A case of orbital cysticersosis that presented with recurrent orbital inflammation for almost a year” is presented. An interesting point for this case is the rather delayed diagnosis in this case. The problem of the cysticercosis is common for the tropical world; however, the expansion to the non tropical region can be seen due to good transportation system at present. Indeed, due to the better diagnostic tool and concern on the cysticercosis, the trend of increased intraocular comparing to extraocular cysticercosis can be observed.² Hence, the physician in charge should think of intraocular cysticercosis in any cases with unexplained intraocular abnormalities. The presumptive diagnosis is usually by orbital imaging because of its highly specific appearance (parasitic cystic appearance).³ However, the differential diagnosis of other intraocular pathologies such as lymphoma is important since it is non-conclusive in some difficult cases. In the report by Rastogi and Jain, a considerable high rate (41%) of the cases needs more complex diagnostic tools rather than simple imaging. The fine needle aspiration to get the specimen for final definitive diagnosis is usually needed in those difficult cases.⁴
