Overview

On X-ray imaging, systemic lupus erythematosus (SLE) may be characterized by different features regarding the present complication. The most common characteristic findings of SLE in X-ray include thumb printing sign in the abdominal X ray, blunting of the costophrenic angle due to pleural effusion, cardiomegaly, hepatomegaly, osteoprosis, tenosinovitis, and other manifestations based on the complications.

X Ray

Findings on an X ray imaging for systemic lupus erythematosus (SLE) depends on the organ system involvement and may include the following features.[1][2][3][4][5][6][7][8][9][10][11][12]
