Lingual Foregut Duplication in a Middle-Aged Adult: Fig 1.

Abstract

SUMMARY:Lingual duplication cysts are rare in the pediatric population and exceedingly rare in adults. Imaging is an important part of the evaluation of lingual lesions and is helpful in defining the location and extent for surgical planning. We present a lingual duplication cyst and discuss the imaging findings and radiologic differential diagnosis. Migrational anomalies during fetal life can result in histologically normal tissue that arises in unexpected locations. When these anomalies result in mass lesions, they are called choristomas. Foregut duplication cysts are a form of choristoma in which gastrointestinal or respiratory epithelium is found in a mass arising in the neck or chest. Foregut duplications constitute approximately one-third of gastrointestinal duplication cysts, and they are usually divided into bronchogenic, esophageal, and neurenteric forms. However, foregut duplication cysts will occasionally arise in locations that do not correspond to this classification scheme. For example, 0.3% of enteric duplications occur in the oral cavity.

Congenital choristomas of the oral cavity in children

“…Almost all oral cavity choristomas are diagnosed in childhood, but these lesions will occasionally be encountered in adults 10. In this scenario, the prognosis and treatment options are the same, as is the radiologic evaluation.…”

Rapid Development of a Simple Ranula in a Child

“…1 The differential diagnosis includes a vascular malformation such as a lymphatic malformation or venous malformation, dermoid, lipoma, foregut duplication cyst, infantile hemangioma, and pyogenic granuloma. 9 Infantile hemangiomas are benign vascular neoplasms that usually present as well-demarcated, flat red patches that do not spread outside of their anatomic boundaries. The most common vascular malformation is a lymphatic malformation, previously referred to as lymphangioma and cystic hygroma.…”

Intralingual Cystic Mass in an Adolescent with History of Hydatidosis: Case Report

“…1/3 of gastrointestinal duplication cysts occur in the foregut, and foregut duplication cysts (FDC) are classified as bronchogenic, esophageal, and neuroenteric. 5 DCs are lined with respiratory, gastric, squamous, or ciliated epithelium but mostly combination of these. 5 0.3% of these cysts occur in the oral cavity and they arise relatively rare from 1/3 of anterior tongue.…”

“…4 The differential diagnosis of a mass in the anterior tongue includes venolymphatic malformations, hamartoma, neurofibroma, teratoma, haemangioma, squamous cell carcinoma, glandular neoplasms, thyroglossal ductus cyst, ranula, lingual thyroid, cyst hydatic, dermoid cyst, and DC. 5,[9][10][11] In this case since patient had a positive history of cyst hydatic operation six months ago, at first we presumed the mass as lingual cyst hydatic (LCH). Hydatidosis commonly appear as cystic lesions and these characteristically grow slowly (1-2 cm/year).…”
