Isolated Lingual Cysticercosis: A Report of Three Cases and Review of Literature

Introduction: Cysticercosis is caused by the larval stage of Taenia solium, the pork tapeworm. It has a relatively high prevalence in developing countries because of the co-existence of poor sanitary conditions and domestic pig raising. However lingual cysticercosis is a very rare occurrence even in countries with very high prevalence of cysticerci infections. Case presentation: We report three cases of isolated lingual cysticercosis after excluding intracranial or orbital cysticercosis with clinical, radiological and ophthalmological examinations. Diagnosis of lingual cysticercosis was established by the characteristic appearances on Ultrasonography (USG) and Magnetic Resonance Imaging (MRI). Conclusion: USG and MRI are excellent diagnostic tools to establish a diagnosis of lingual cysticercosis and helps in differentiating from other cystic lesions of tongue.
