low attenuation lymphadenopathy

Low attenuation lymphadenopathy refers to abnormal lymph nodes that on CT appear to have lower attenuation than other soft tissues. This category can be split into two types:

• cystic (necrotic) lymph nodes
  • metastatic carcinoma (or lymphoma)
  • infections (tuberculous or fungal)
  • cavitating mesenteric lymph node syndrome related to celiac sprue
  • inflammatory necrotic disorders (e.g. Kikuchi-Fujimoto disease)
• fat-containing lymph nodes
  • Whipple disease
  • extra-adrenal myelolipoma
