Supplementary Material for: An Unusual Presentation of Periorbital Cysticercosis Mimicking Dermoid Cyst.

Introduction
Cysticercosis is a parasitic infestation caused by Taenia solium, which is a pork tape worm. Humans are the definitive host, and pigs are the intermediate host. It is more prevalent in low socioeconomic regions with poor hygiene and among populations where undercooked pork is consumed.
Case report
We hereby report an uncommon site of cyst lodgement and duration of presentation in a 24-year-old male who presented with a firm, non-tender mass over the supero-medial aspect of the right orbital rim, superior to the medial canthal tendon for the last 9 years. Chronic presentation and location of the mass led to the tentative diagnosis of a dermoid cyst. Hence, a CECT orbit was advised to assess the extent and attachment of the mass. Unexpectedly, a cystic lesion with hyperdense nidus, suggestive of cysticercosis, was identified. Histopathology of the excised mass confirmed the diagnosis of cysticercosis.
Conclusion
Our case emphasizes the importance of uncommon site and chronic presentation in cases of cysticercosis.
