Contrast enhanced evaluation of Nasolabial cyst-a quest for the elusive

Nasolabial cyst is an uncommon, soft tissue cyst of non-odontogenic origin found in the maxillofacial region. It presents as a slowly enlarging, asymptomatic swelling in the nasolabial region. Being a soft tissue cyst, it cannot be appreciated radiographically. We present a case of nasolabial cyst in a 60 year old female patient who reported to us with a swelling in the left nasolabial region. Iodine contrast agent was injected into the cyst followed by a series of images to evaluate the entire extent of the lesion. This paper highlights the importance of use of radiographic contrast agent in the diagnosis of this rare lesion. A brief review of literature with emphasis on the conventional radiographic and computed tomography findings is presented.
