Fig. 1From: Isolated thoracic intramedullary Erdheim-Chester disease presenting with paraplegia: a case report and literature reviewPreoperative magnetic resonance imaging shows intramedullary mass lesion with iso-intense on T2-weighted images (WI) and iso- to slightly low-intense on T1-WI on T2-4, which was heterogeneous enhanced pattern with cord swelling and edema from C7 to T6 (red arrows) (a). There was a single lesion on T2-4 with maximum standardized uptake value (SUVmax) of 3.14 and no systemic lesion on whole-body 18F-fluorodeoxyglucose positron emission tomography/computed tomography (blue arrow) (b)Back to article page
