Risk calculators and risk factors for Syphilis CT


CT scan is not diagnostic of syphilis. However, non-specific CT findings may demonstrate complications of syphilis including pulmonary, cardiac, neurological, gastrointestinal, and bone findings.[1][2][3][4][5][6]


On CT scan, syphilis may present with various non-specific findings including:



  • Double ring appearance of the aortic wall with a hyperdense outer rim and hypodense inner rim[2][3]
  • Thickening or calcification appearing as contrast enhancement of aortic wall[2][3]


  • Areas of decreased density suggesting cerebral infarction[8][9]
  • Syphilitic gumma appear hypodense with precontrast
  • Focal or diffuse extraaxial enhancement
  • Non-specific white matter lesions




  • Perivascular fluid collection
  • Periaortic lymph node enlargement
