Rapidly progressive neurological deterioration without magnetic resonance imaging abnormalities: intravascular lymphoma.

Early detection of intravascular large B-cell lymphoma by 18FDG-PET/CT with diffuse FDG uptake in the lung without respiratory symptoms or chest CT abnormalities

Intravascular large B-cell lymphoma (IVLBCL) is a rare and aggressive subtype of systemic extranodal non-Hodgkin diffuse large B-cell lymphoma (DLBCL). We report a rare case of IVLBCL who showed diffuse 18F-fluorodeoxyglucose (FDG) uptake in the lung in FDG-positron emission tomography/computed tomography (PET/CT) without respiratory symptoms or chest CT abnormalities. Serum biochemical studies...

A Case of Recurrent Ischemic Stroke due to Intravascular Lymphomatosis, Undiagnosed by Random Skin Biopsy and Brain Imaging

Intravascular lymphoma (IVL) is a rare disease characterized by the proliferation of lymphoma cells in the lumen of the small blood vessels. Although early diagnosis of IVL is important to prolong survival of the patients, its atypical symptoms and clinical course often delay its diagnosis. More than half of the patients are diagnosed at autopsy. We report a 68-year-old man who presented with t...

Cranial Nerve Lymphomatosis Magnetic Resonance Imaging Findings in a Case of Mantle Cell Lymphoma

Intravascular large B-cell lymphoma presenting as dementia and hemolytic anemia.

BACKGROUND Intravascular lymphoma (IVL) is an uncommon disease characterized by atypical lymphoid cells growing inside the lumina of small vessels. The diversity of clinical presentation due to possible involvement of multiple organs often complicates its diagnosis. CASE REPORT Here, we report on a case of IVL with rapidly progressive dementia and Coombs-negative hemolytic anemia. Interesting...

Progressive visual and hearing loss as looming manifestations of spinal meningeal melanocytoma

  Abstract   Meningeal melanocytoma is a rare tumor of nervous system, which originates from leptomeningeal   melanocytes. The locations of melanocytoma in the nervous system are most frequently in the posterior fossa or along the spinal cord, and usually appear as an extra-axial mass. The manifestations of tumor are most often due to its compressing effect on adjacent nervous structures that c...
