Nasopalatine duct cyst

An incidental finding of a well-defined high T1 signal lesion was made on a MRI brain. CT was performed for clarification and shows a smoothly marginated expansile lesion that communicates with the nasopalatine duct. The appearances are characteristic of nasopalatine duct cyst. The T1 signal in these cysts can be variable, depending on the nature of the cyst contents.
