Contrast-enhanced computed tomography (CT) of a patient with erythrodermic psoriasis. (A) Three-dimensional (3D)-CT image before infliximab treatment revealing systemic vasodilatation and bilateral axillary (wide arrow) and inguinal (narrow arrow) lymphadenopathy. (B) 3D-CT image after infliximab treatment. Improvement of vasodilatation and lymphadenopathy is apparent. (C) Axial CT image before treatment revealing vasodilatation, diffuse skin thickening, and subcutaneous fat stranding (arrowheads). (D) Follow-up axial CT after treatment revealing improvement of these imaging findings. (E, G) Contrast-enhanced CT before treatment revealing lymphadenopathy of axillary (wide arrow) and inguinal regions (narrow arrow). Note the thickened skin and subcutaneous fat stranding (arrowheads). (F, H) Follow-up CT after treatment revealing improvement of these findings.
