Geographic appearance is a term used in imaging, and other clinical fields (e.g. histopathology) to describe lesions with a well-circumscribed margins with adjacent tissues. The term derives from the somewhat similar appearance of the outline of countries on a map or the clear demarcation formed by the coastline against the sea 1.
The usage is most commonly found in the reporting of bone lesions, especially eosinophilic granuloma e.g. skull. It can also be used to describe variations in hepatic fat deposition 2.
In describing bone lesions, the boundary need not be sclerotic.
