Magnetic Resonance Imaging Appearance Of Erythema Nodosum: A Case Report

Erythema nodosum (EN) is the commonest inflammation of the subcutaneous fat tissue (panniculitis). Erythema nodosum (EN) requires an interdisciplinary approach and exclusion of all underlying causes. We present a case of an 18-year-old female with a history of recurrent streptococcal infections over the years, who developed pain and swelling in the left ankle. To evaluate the persistent ankle swelling, the physician ordered a magnetic resonance imaging (MRI) of the left lower extremity. The MRI appearance of EN has not been described in detail in the literature so far.
