Morton Neuroma eMedicine Radiology

Description: Morton neuroma, or interdigital neuroma, is a common condition that involves enlargement of the interdigital nerve of the foot. Morton neuroma most commonly affects the third intermetatarsal space, but it can also affect the second intermetatarsal space, although it does so less often. Lesions in the fourth and first interspaces are unusual. The etiology remains controversial, and treatment varies among practitioners. Diagnosing the condition involves clinical judgment, and in difficult cases, imaging may be useful in determining the precise diagnosis.
