An Unusual Presentation of Periorbital Cysticercosis Mimicking a Dermoid Cyst.

INTRODUCTION

Cysticercosis is a parasitic infestation caused by , 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 PRESENTATION

We hereby report an uncommon site of cyst lodgment and duration of presentation in a 24-year-old male who presented with a firm, non-tender mass over the superomedial 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 an uncommon site and chronic presentation in cases of cysticercosis.
