Abstract

A 66-year-old cachectic female with underlying anorexia nervosa and lower limb weakness was referred for a spinal Magnetic Resonance Imaging. Imaging appearances were initially thought to represent underlying systemic pathology involving bone marrow or inadvertent wrong selection of imaging sequences. It was, however, established that unique imaging appearances are secondary to 'Flip-Flop' phenomenon owing to underlying nutritional status of the patient. 'Flip-Flop' phenomenon on the Magnetic Resonance Imaging is result of an underlying pathological process of serous atrophy of bone marrow. Appreciation and recognition of this phenomenon will help in the correct interpretation of the images and leads a clinician toward appropriate management.
