Abstract Cysticercosis is a condition in which humans are infected by the larval form of Pork Tapeworm Taenia solium. Isolated lingual cysticercosis is a rare entity due to the high muscular activity and metabolic rate of tongue which prevents the development of larva. We present a series of three patients with isolated lingual cysticercosis. One patient was treated by medical management while the other two were treated with surgical excision followed by medical therapy. All patients are asymptomatic after repeated follow ups.
Cysticercosis is the most common parasitic disease of the central nervous system [3]. However Extra neural cysticercosis, which is also very common, infects muscles, heart, lung, peritoneum, eye and subcutaneous tissue [4]. Isolated lingual cysticercosis is a rare entity due to the high muscular activity and metabolic rate of tongue which prevents the development of larva [5]. It can be a diagnostic dilemma due to resemblance with various other benign tumors. We present a series of 3 patients with isolated lingual cysticercosis.

Case Series Introduction
Case 1
Cysticercosis is a condition in which humans are infected by the larval form of Pork Tapeworm Taenia solium. Humans act as both definitive and intermediate hosts of Taenia solium [1]. It can occur due to consumption of under cooked pork as well as through faeco-oral route [2].
A 12 year old boy presented to the ENT outpatient department with a painless progressively increasing midline swelling in the anterior one-third of tongue since past 3 months (Fig. 1). The patient was asymptomatic. On intra oral examination the swelling was firm, non-tender, nonpulsatile with diffuse margins and normal overlying mucosa. There was no restriction in tongue mobility and no other similar swelling anywhere else in the body. On fine needle aspiration cytology a provisional diagnosis of infected parasitic cyst was made. Magnetic resonance imaging (Fig. 2) showed subcentimetric T2 mildly hyperintense lesion in midline within the intrinsic muscles of tongue with small eccentric ill defined T2 hypointense nodule within the lesion suggestive of a scolex. It also helped exclude a similar lesion in brain and eyes. Patient was pretreated with Tab Prednisolone 30 mg OD for 5 days followed by Oral Albendazole 15 mg/kg which was given for 28 days.
