Abstract
PURPOSE
To study the clinical presentation, radiological features, diagnosis, and treatment response in subconjunctival and atypical orbital myocysticercosis.
METHODS
Retrospective analysis of diagnosed subconjunctival and atypical (strabismus, diplopia, and blepharoptosis) orbital myocysticercosis was performed. A diagnostic criterion (2 of the 3) among clinical features, radiological findings, and treatment response was used in our study. A minimum of "post-treatment" follow-up of 12 months was observed.
RESULTS
Thirty-five patients were included with a mean age of 16 years having male predominance (n = 22, 62.8%). All had a unilateral presentation, with 24 (68.6%) patients having subconjunctival cysticercosis, of which 22 were located in close proximity of the rectus muscle insertion. At presentation, 10 patients had diplopia, 7 had strabismus, and 6 had face turn. Pseudo Duane's and pseudo-Brown's syndrome were noted in 5 and 4 patients, respectively. Radiologically, single muscle myositis without scolex was seen in 12 (34.3%) cases. All patients first received medical treatment, and surgical intervention (cyst removal) was attempted after treatment failure. Complete resolution of symptoms was noted in 22 (after medical treatment only) and in 8 (after surgery).
CONCLUSION
In the majority, the subconjunctival cysticercosis is found in proximity to the rectus muscle insertion, as a part of orbital myocysticercosis. In atypical scenarios, a satisfactory response to medical treatment can be considered as diagnostic of cysticercosis.
