Lymphoid tumors of the chicken have been shown to be readily transplantable by the use of viable cells. Pentimalli (29) and Olson (25, 27) have described the isolation of such strains from what was thought (28) were rare cases of neoplasia, but which had all the characteristics of the condition designated by Feldman and Olson (9) as lymphocytoma. Burmester and Prickett (7) reported the developm...

Lymphomatosis cerebri (LC) is a rare form of primary central nervous system lymphoma (PCNSL). Little is known about cases of LC with spinal cord involvement. Among the 11 PCNSL patients treated in our hospital during a four-year period, we identified two cases of LC with spinal cord lesions. One showed a spinal cord lesion followed by leukoencephalopathy. The other showed a spinal cord lesion a...

A 29-year-old immunocompetent woman was admitted in 2006 with ataxia, limb weakness, generalized dystonia, and vertical diplopia that developed after a febrile episode. Brain magnetic resonance imaging (MRI) revealed the presence of extensive periventricular white matter lesions that did not enhance after gadolinium injection. As low titers of cytomegalovirus-IgM antibodies were found in the se...

Intravascular lymphomatosis (IVL) is a rare and clinically devastating form of extranodal B-cell non-Hodgkin's lymphoma. We performed a comprehensive analysis of the literature on IVL's published between 1959 and 2011 and evaluated the natural history as well as identified prognostic and predictive factors in patients. Nonparametric two-tailed Mann-Whitney U-test and Mantel-Cox log rank test we...

MR imaging data were reviewed retrospectively in four male patients (32 to 74 years old) with histologically confirmed intravascular lymphomatosis (IVL), a rare, aggressive form of non-Hodgkin lymphoma. MR findings included infarct-like lesions (n = 2), focal parenchymal enhancement (n = 3), dural/arachnoid enhancement (n = 2), and, in one case, nonspecific, patchy foci of increased signal in t...
