ERI OUCHI, Presenter: Nothing to Disclose

Toshihiro O'Uchi MD, Abstract Co-Author: Nothing to Disclose

Nurolymphomatosis is a rare clinical entity that is defined as infiltration of the peripheral nervous system by a known or unknown hematological malignancy and is difficult to diagnose. Usefulness of 18 FDG-PET-CT in diagnosing of NL is emphasized in recent case presentations. According to our experience of nine cases of NL which includes four cases of intravascular lymphoma and five cases of DLBCL, combination of MRI with Gd and 18 FDG-PET-CT is useful to demonstrate involvement of NL due to those morphological and functional images. Seven cases out of nine showed abnormal findings both of imaging modality. Primary NL was recognized in three out of five cases of DLBCL. Understanding of clinical symptoms and typical findings of imaging modalities such as 18 FDG-PET-CT and MRI is very importnant to diagnose NL properly.    Ther purpose of this exhibit is: 1. To review neurolymphomatosis, which is a rare entity and usually difficult to diagnose 2. To learn the typical features of NL in 18 FDG-PET-CT and MRI
