Abstract:
Heterotopic gastrointestinal cyst of the oral cavity is a rare congenital lesion that may arise from ectopic undifferentiated endodermal cells. Imaging, particularly MRI, is useful for surgical planning. On MRI, the cysts typically demonstrate high signal on T2-weighted sequences and variable signal on T1-weighted sequences, which can resemble other conditions, such as dermoids. On histology, the appearance of these lesions can be variable, and may include stratified squamous, simple and ciliated columnar, as well as foveolar and intestinal-type epithelia, often surrounding by smooth muscle. Complete surgical excision is the treatment of choice.

Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
