Neoplastic Angioendotheliomatosis

MR imaging of multiple cerebral infarctions in angiotropic lymphoma (neoplastic angio-endotheliosis)

“…To our k n o w l e d g e , M R I studies of only four patients with N A E have been reported in the literature [3][4][5]. W h i l e there were multiple lesions in both the white and grey matter, they were p r e d o m i n a n t l y found in the white matter.…”

Intravascular Lymphomatosis Mimicking Primary Central Nervous System Lymphoma: A Case Report and Literature Review

“…However, some authors have reported that extravasation of malignant lymphocytes can occur to some degree in the late stage of IVL [1, 7]. To the best of our knowledge, there have been 4 cases of IVL in which postmortem examination revealed a brain mass and 5 cases of tissue-proven IVL in which MRI showed a brain mass (table 1) [8, 9, 10, 11, 12, 13, 14]. Our case is notable because it is the first description of DWI of a brain mass in a patient with IVL.…”

Intravascular malignant lymphomatosis: diffusion‐weighted magnetic resonance imaging characteristics

“…Cerebral MRI findings of intravascular malignant lymphomatosis include patchy high signal lesions of the cerebral white matter with or without cortical involvement on T2-weighted images (7,10,12,15). Leptomenigneal enhancement can occur, and, if present, indicates microinfarcts of the meninges or sluggish flow through their vessels (15).…”

“…Leptomenigneal enhancement can occur, and, if present, indicates microinfarcts of the meninges or sluggish flow through their vessels (15). High signal intensity lesions in the spinal cord or conus medullaris are also characteristic of intravascular malignant lymphomatosis (4,10,12). NAGAMI et al (11) reported a rare case of intravascular malignant lymphomatosis with massive tumor in the superior sagittal sinus.…”
